I have noticed a lot of people showing interest in possibly going down the road of turbo or even superchargers for their 1nz lately. I just wanted to give everyone the heads up that I have been down this road with turboing my xB and am open for questioning as always if anyone needs any help in converting to a turbo setup. I also do have some parts still available that may be of some use to you guys if you decide to go turbo. I loved the boost in the xB as the car really comes to life and becomes very spunky and quick/responsive to the boost. The only downfall, as most know by now is the fuel management setups. Piggybacks just dont fair well with our ECU's and standalone is a route most people arent willing to take. Well, anyway, I think if you can deal with having *CEL's at all times and dont mind pulling fuses every couple of days to make the car run correct, you should go ahead and do it. If you dont think you have the knowledge to troubleshoot if something happens, or are not the type to be under your hood EVERY day, and I mean EVERY day then this is not for you.
*The only CEL I ever threw was a system too rich code from the injectors i put in
P:S....what the hell ever happend to our F/I forum......Can we really get that going already please :come:

Im thinking about turboing my xA, but i wanted to hear past experencies from other people that have already done this. I didnt know about the fuel management nor the piggyback problem, so i guess ill have to see into stand-alone... I dont know.

I guess the real question is :Is it worth it?!?

well, if your doing the install yourself, and you have some decent knowledge on working on motors or the basics of how to turbocharge an N/A motor or how a turbo even works then yea, go and do it. You dont hafta do a stand alone cause if you do you will lose your daily driveability not to mention things like your VSC, Traction control basically all the electronically controlled features of the car. If you dont wanna pull fuses which is the easiest way to keep it running good, you can wire in a switch to the ignition or even a toggle switch inside the cockpit to reset your EFI system.

I guess the real question is :Is it worth it?!?


YES...Its worth it....

Were you really under the hood EVERY day? What would always go wrong and why were you throwing CELs ?

Were you really under the hood EVERY day? What would always go wrong and why were you throwing CELs ?

Nothing was really wrong, Im just anal and go over everything like 5 times after some hard runs...the only CEL I ever threw with the turbo was a P0172(system too rich bank 1) and it was because of the larger injectors I put in. It was getting too much fuel at idle and would throw the code no matter what...the only problem is that its a hard code that also throws the VSC and Trac light on but they are still in working condition...dont let this shy you away though cause the boost was sick in this car.

you were running 330cc GTS injectors right?

yup

yup

How much did a set run for you? I owned a GTS, but they came with the car. :lalala:

Did you piece together your whole kit or did you buy it complete and change parts?

Whats your reccomendation for a decent kit thats out now?

yup

I got the set from JDaniels for like $100 used. They are around $140 a pop new!!! Definitely grab them from a junkyard if you can. Its gotta be like an 03-04 and they will be good enough to use. I changed parts with the kit. I didnt use the fuel management system that came with the kit because it is very innacurate and unstable. I got the injectors, rail, 255lph pump, aeromotive 1:1 Fuel pressure reg, custom return line setup etc. Right now as far as decent kits, I dont think there is one out there if that makes any sense :rofl: I dont like the idea of the turbo being behind the firewall on my old kit, I would much rather see a top mounted turbo. I would see if you could have someone custom fabricate you a equal length turbo mani w/ an external wastegate. One thing that I never got to mess with was trying to fab a custom intake w/ a larger MAF port than stock. I was using the stock airbox on my setup and it really put a hurting on my performance. My MAF used to wig out because of all the compressed air it was seeing through this small diameter housing. I would maybe use a slightly smaller intercooler to decrease any minimal lag you may see to begin with, and replace with an Intercooler sprayer. Then my friend, the rest is up to you. That is the hard way out, but if you want a kit, I would wait to see whats gonna happen at SEMA cause I have a feeling a few companies may be showcasing some stuff for the near future. There were a few companies waiting to release a kit, one of them was RevHard which I am dissapointed this never came out yet. Another one that comes to mind is PSI racing....another one that suddenly went back into hiding. Dont even waste your time with Greddy unless you got some hookup with them and they are willing to re program the Emanage for you to run on the USDM 1nz...might wanna convert to their MAP tuning interface while your at it. ZPI is supposedly going to develop a turbo for the xB, but I dont think that they realize that this is a whole different ball game from the tC. They are used to working with a vehicle that is designed to run an optional supercharger so it is prepped to see the added boost, as the xB is far far from that. I am very curious to see how their venture goes, I just hope they dont try to cut corners like everyone else has out of frustration with the management system that curses us from day one from the factory.

awesome. I can grab a set of used injectors easily.

Hmm a custom made manifold sounds like downtime on the car which I really cant do since its a daily driver and I work 5+ days a week.

I heard about the Revhard kit from my little brother. One of his friends has an RS2 xB and has been interested in boosting it. I am friends with a guy who has an account with Greddy but I doubt that will give me much pull in gettting them to help with the emanage.

So did where did you get your "kit"? turbo-kits.com?

As we've discussed in PMs, I dont need to blow anyones doors off. I just want it to run and give me some torque and driveability.

Thanks so much for answering my questions.

Someone, please write Apexi a letter telling them to come out with a plug and play ECM for the xB with base maps loaded onto it.

Yea, Greddy is such ball busters and the only person who I know who was able to get a reprogram from them was my Regional and District Scion corp managers. It was the basic greddy kit on a RS 1.0. The funny thing was, they never wanted to run me, maybe it was cause they were running like 4-5 psi, I was running 6-8psi depending on my mood :P :lalala:
I actually bought the kit from that guy JDaniels and I cought it at a killer price back in early June. Definitely enjoyed every minute of it and got nothing but compliments about it. I actually sold the box to a guy who joined my car club so I get to see it a lot...actually saw it last night at our local Fri night meet spot(friday night import/muscle scene w/ some high hp cars running) and I made him run a turbo D-motor civic w/ pistons, rods, sleeved block, edelbrock intake mani etc. and the same Garett T20 as I was running and my box beat the civic by a couple cars lol.

Also, dont worry about the questions, thats why I kind of started the thread...I think that some of the other F/I guys should come on out and check this thread out and give their input and maybe make this a sticky since we cant get our F/I forums going yet...I would change the thread title to "Everything and anything about going/being Forced Induction" :rofl: :pray: :pray:

BrianxB, you said you were reverting back to stock... was that just stock suspension? Sounds like you're planning to keep the box and go FI. :thumbs:

i'm not a turbo guy, but if you have a supercharger Q, i'll do my best to help you out....

V, i figured out what my code was. (evap leak...small....)
just a side effect of my install...

also, made this an anoucement till we get a FI forum...

Yes, Dave is definitely the man to speak to when dealing with the superchargers...he has a very clean setup.
Hey Dave, Stuart actually threw that same code when he did his turbo...he thought it was due to the return line setup...no biggie, just a minor glitch.

Ok, time to step up with a question.

Once my egg is off warranty I have plans for the 1NZ. I want to supercharge my xA, plain and simple.

Now I know that Blitz is the big guy when it comes to Superchargers and the 1NZ-FE engine, however, I have also noticed in the parts section that Power Enterprise also has a kit as well. Now the obvious differences are the PE is a centrifugal design and Blits is a Roots style supercharger. Are there any benefits to the PE kit (if it fits the xA) over the Blitz in terms of performance or will they give equivalent gains?

I personally love both kits, and the whine of a supercharger just gets me going. dgHotLava what has been your experiences and what am I looking at in terms of workload for installation and tuning? I have about 2.5 years before I go F/I so there is plenty of time to research and gain knowledge on the process.

Ok, time to step up with a question.

I dont think Dave is online right now, but I will briefly answer the question and let him finish the answer tommorow. Theres one thing that I hafta correct you on though before we get any further, the Blitz supercharger actually is a centrifugal supercharger. It is different in essence to the PE because it replaces the stock intake manifold as the PE is a true bolt on affair which I believe mounts on to an alternator bracket(help me dave lol), with tapping the oil return line as being probly one of the hardest part of the install. I do not know exactly if the PE fits the xA, but I couldnt see why not cause your not running an intercooler and if you decide to the only thing I could possibly see different would be the space you have to route charge pipes. I think the only difference in the engine bay of the two would be the location of the strut towers which shouldnt be an issue and the washer fluid tank design is different(hence why the TSI kit is really for an xA). I would go with the PE kit, as it will definitely outperform the blitz and seems to run better than the blitz as well

i'm not a turbo guy, but if you have a supercharger Q, i'll do my best to help you out....

V, i figured out what my code was. (evap leak...small....)

That is the same code that I am still getting now even without the turbo. I believe in my case that it is from the return line setup that I made and its registering a small leak due to hole I drilled in the housing for the return line. I have had NO driveability problems with the code, just stupid dash lights....

the PE does not fit the xA....at least if you like having a hood. the PE unit sits up on top of the motor...
the oil returen line is not the hard part of the PE kit. (they give you a new oil pan with the return line bung welded in already. just drain the oil and swap the pan.)
there is a 4 mil vacuum line you run back into the fuel pump. this and drilling the fuel pump canister for the new pressure regulator are the hard parts.

the PE300 is mounted off of the motor mount and engine block.
power is driven by the alternator pulley. they give you a new spindle for the alt.

yeah, no issues driving it. just some lights in your face.

it is the same code you get if the gas cap is not on all the way....

i might get this once every two months. check the code, pull the fuse. all is good.

ok well...here's my question...I want to supercharge my xA with the blitz unit. I want to know EVEYTHING about supercharging my car...like is it a DIY for a beginner border line intermedite kinda guy, how is it with the car's ecu...blah blah blah...I want to know everythign taht you coudl possibly throw at me, I have no knowlege whatsoever about *blank*charging. thanks for the help!

BrianxB, you said you were reverting back to stock... was that just stock suspension? Sounds like you're planning to keep the box and go FI. :thumbs:

hey chris. Well teh car was almost back to stock because
A. My AVIC N1 was stolen
B. One of my air cylinders blew out and EAI is out of business now.
C. A week after my Nav was stolen, someone fools tried to steal my wheels. My alarm went off of course (you would think that the bright blue LED is there for a reason) and I came out with the heater. They took off in a large Fordish SUV. (its hard to tell when your woken up at 430am and you reach for your gun rather than your glasses).

Now I have insurance money for the AViC and need to spend it on something one of these days.


Simplyscion-

I dunno who that JDaniels guy was. So, was your kit something pieced together or did it start as a complete kit?

Damm bro...sorry to hear that string of bad luck, hope it ends for ya real soon. My kit was the TSI kit, and the only thing pieced together was the fuel setup, and my gauges and other lil things here and there.

I guess the real question is :Is it worth it?!?


YES...Its worth it....

YES, it is!

Sorry guys, haven't been around much as of late.

I'll try and hit this as much as I can.

There is a new kit on the horizon. I'll post more when I can.

I found out some more new info, but have to confirm before I post more about it.

I really hope you will keep me informed so I can go to work with the new owner of my car and get this thing rockin.

thats is good news Brad.

i knew something was going on....

At Sema, hks will be debuing their turbo kit for the xB as well. if anyone is going please get info for all of us on it, I havent spoken w/ my friend at hks for months, BUT the last time i spoke to him, testing was pracitcally complete.

.... Theres one thing that I hafta correct you on though before we get any further, the Blitz supercharger actually is a centrifugal supercharger....
Are you sure about that? I was pretty sure it was a twinscrew type sc.

http://www.xtremeautos.ie/images/comp-6.jpg

What is everyone using to read thier codes? laptop, shop buddy, code readers, 6th sense?

Damm bro...sorry to hear that string of bad luck, hope it ends for ya real soon. My kit was the TSI kit, and the only thing pieced together was the fuel setup, and my gauges and other lil things here and there.

Thanks. I hope so too. Im sick of looking at my wheels sitting in my closet.

Ill read up on that TSI kit.

HKS kit! Woohoo.

The greddy kit is still not availible for a US xB right?

i believe they ditched the turbo setup and have a supercharger setup now.

i believe they ditched the turbo setup and have a supercharger setup now.

Yes that is true. Greddy stopped production of the turbo because for the kit to be as complete as they would want it to be, it would retail for 4-5g's. Nobody would pay that much for the gains that would come from the kit. Instead they have built a supercharger kit that will be released around christmas and is suppose to produce about an extra 35hp....

can't wait to see it...

i hate this thread only because its always tempting and calling me...you want to f/i someday....do it....do it..... :lalala:

35hp sc friggin drool??

**do it.....do it....**

hehehe

Glad to see all this interest in FI on the Scions. I have been running my PE300 for over a year now. I have some plans for a few winter projects to squeeze a few more hp and hopefully hit 150hp. But 141hp will do for now. :P

yup

How much did a set run for you? I owned a GTS, but they came with the car. :lalala:

Did you piece together your whole kit or did you buy it complete and change parts?

Whats your reccomendation for a decent kit thats out now?

I got the set from JDaniels for like $100 used. They are around $140 a pop new!!! Definitely grab them from a junkyard if you can. Its gotta be like an 03-04 and they will be good enough to use. I changed parts with the kit. I didnt use the fuel management system that came with the kit because it is very innacurate and unstable. I got the injectors, rail, 255lph pump, aeromotive 1:1 Fuel pressure reg, custom return line setup etc. Right now as far as decent kits, I dont think there is one out there if that makes any sense :rofl: I dont like the idea of the turbo being behind the firewall on my old kit, I would much rather see a top mounted turbo.

When i do go turbo with my xA, its all going to custom made work. The same person that did my friends celica is now going to do my car. (By the way those are the injectors i plan on using because his is a GT. ) Beauitful custom made equal length header and the great part is my mechanic said he can even use my Injen CAI to his advantage because he just cuts a peice off and runs the intercooler through the same tubing as the normal CAI. Its going to be a costly project because my mechanic is very picky with the products he uses (which si good to my car, not my pocket). I was just wondering what turbo size do you recommend for this setup and what intercooler should i be looking at. I would like to run 8lb of boost at first. Then hopefully with a redone engine (if possible) run 12lb tops. I was thing of going with a T3/T2, but im not sure. Give me some advice.

I got the TSI kit w/ Apexi SAFC-II for fuel management.

4 Upgraded Fuel injectors.



As soon as I swapped out my injector, I feel better ride on idle and all but after 4rpm.

I got check engine light on. Code is saying misfiring + fuel running too lean.

I thought this will be fixed at the turbo tuning shop but no...

they tried to do everything with safc II but we failed.

Now i believe i need more fuel but 310cc injector is good upto 200 hw.... hmmm...

What do you guys recommend?

Fuel pump? rail? and what's converting to fuel return system? should i get the 5th injector?


Any help!!!!!!!!!!


Definitely go with the bigger rail, fuel pressure regulator, and convert over to a return line setup. The max fuel psi is only gonna be around 52 psi but its better than the stock 45 psi. I take it you are using the TSI kit, so if all else fails, try the extra injectors they supply with the kit. I have the injectors/black box unit used for sale if you didnt get one with your kit. I also have a brand new in the box aeromotive 1:1 for boost fuel pressure regulator. for sale if you wanna convert to the return line setup. I did all this stuff for my turbo setup on the xB and it worked. You should really get rid of the S AFC and get something like Emanage. I had the Camcon but didnt get the greatest results. They werent consistent. Also, change your plugs to something a couple steps colder like a 7 range. Get copper plugs, and gap them to like .025. I hope this helps out a lil bit. You sohuld really check out the mini turbo/supercharger thread at the top of the page and ask questions there cause they will get answered quicker.


Thanks for all the info Simplyscion.

but i have few questions to ask.

1. I am replacing S AFC with E-management, since emanage can boost 50% more fuel control. You think this will solve it or i need more ?

2. trying to get the colder range spark. do you know any site or link where i can get them? how about those on e-bay?

3. is it necessary to get all fuel pump, and rail? cuz BBist is saying it does not will help that much. Steve said e-management should solve this problem.

4. if not, how much for boost fuel pressure regulator?

The emanage may help solve your problem. What really sucks is that Im over here in NY and its hard to see exactly what is going on when I cant actually get my hands on it. As far as the plugs go, anything with the heat range of 7 will do alright...try the NGK BKR7EY and gap them to .025...these are a platinum but they are good...try to cross reference those with Iridiums or the coppers. It is not necessary to go with a return line setup, but so far everyone I know that has blown a bottom end didnt have a return line for fuel, and they were running violently lean at the point of failure. I would definitely do the return line setup cause it increases your fuel pressure slightly(something Emanage cant do). Also, while changing out your injectors, I think its alsmost a necessity to change out to the Perrin fuel rail to help carry that extra fuel and also you will need it to tap in one end of the fuel rail for the return. After you do some more research about what you wanna do, lemme know what you wanna do with the regualotr as I will PM you with the price instead of posting it up here cause I dont want all the vultures jumpin in on it and trying to snatch it up from me before it could get to you hahah. I got few turbo goodies you might be interested in for good chap prices.

can you give me more detail on the fuel return system?
what i need and how it works and stuff.

Now so far i have e-management, spark plug and fuel rail on my way

can you give me more detail on the fuel return system?

Now so far i have e-management, spark plug and fuel rail on my way

Basically what a return line is used for is to get the extra fuel that wasnt used and recirculate it back into the tank...its more of a better constant flow for the fuel to give you the right amount that you need on tap with adjustability of fuel pressure. What you are doing is putting a bulkhead fitting into the sending unit in the tank, then running a stainless steel braided fuel line back up to the engine bay to a fuel pressure regualator(which allows you to crank up the fuel pressure a bit), then running a line to from the regualtor to the end of the fuel rail.
What you will need for a return line is about 15 feet of fuel line, a few earls AN fittings, an aeromotive 1:1 FPR and I would get a bigger fuel pump while your at it...might as well change it out to something bigger like a 190 LPH while you got the sending unit out of the tank. I would also invest in some larger injectors if I were you...doing all these fuel upgrades, you will want the injectors to be able to handle that extra fuel.

OK so far i have 4 310cc injector

Parts on the way or waiting to be installed is spark plug, e-management, power enterprise 130lph fuel pump, and perrin fuel rail.

Do you think those will fix the problem? is 130 lph big enough?

yea, 130lph is fine...I was running a 255lph and that was completely overkill for the setup. You should be alright with that, just look into maybe doing a return line for safety reasons.

Has anyone seen the turbo manifold available for the 1NZ from TurboNetics yet? I have seen it available in their catalog and its for a T3. Just curious how it mounts...I will have to call them

Hopefully its a top mount...Im sooo sick of seing everything mounted in between the firewall...it gets awfully hot back there :P

Even if its a top mount, I am still going to go with the supercharger. I dont have room for an intercooler anymore with that new front end...

On another note, I already my hands on the turbo kit for the new ride....HAHAHAHA

couple of ?'s.....

ok maybe a dumb one but trying to learn so....do you have to use top grade fuel if you go with the s/c? wondering how different t/c and s/c are

is an s/c less maint then an t/c?

last ? - with an s/c do you need to worry about cooling as much as you do with a t/c setup?

the cooling i was most curious about actually.

if anyone knows a good s/c vs. t/c comparison please point me i will do some reading!

thanks :silly:

I am trying to replace my fuel pump to Power Enterprise 130LPH fuel pump.

I have no clue where the fuel pump is and all.

Asking for all SL people to help me out on this.

Can someone provide me with step by step or some direction towards this ?

taken care of :lalala: ...lemme know how everything works out in the morning

145hp at the wheels from 92hp stock. Greddy E-Manage, RC 310cc injectors, Iridium plugs, and ACT Extreme pressure plate w/ full face disc.

We don't have any codes or problems with the kit on our xB. Greddy will come out with a turbo and super charger set up next year. You might just want to wait untill next year when it comes out (BomexbB). It doesn't seem like you're sure what you want to do with the setup.

Good luck to you...

thx for the head up but Im almost done with this...

fuel pump is in.

nothing too hard...

but stupid perrin fuel rail wont fit.

the end of rail where the fuel line goes is touching the fuel line hole and it wont sit on correctly.

thx to that i broke my fuel injector plastic and had problem with fuel leak....

good thing i had extra sets of o-rings and spare parts.

glad to see perrin did nothing about the rail....

see this... http://www.scionlife.com/forums/viewtopic.php?t=48289

hahahah stupid perrin.... do you htink they are worth it? Im thinking about returning them.... what do you think?

dont return it, you will need it...just do what both Dave and I did and cut off that casted end(drivers side) of the block that looks sort of like a hook and you will be fine.

if you already have it, keep it.

if you want to keep a stock looking valve cover, just grind the hook where it hits....otherwise just cut it off.

im kinda interested in getting a turbo....can someone give me a "wish" list of things that I NEED to get if i decide to go down th turbo route? how much am i looking at?

If your not the handy type that is used to being under the hood and would be able to troubleshoot a problem or issue fairly quickly, then I would go with the supercharger instead of turbo but thats entirely up to you. If done correctly, both units can be virtually almost maintanence free. If you would like to see what is involved in doing a complete and "Proper" turbo setup, look in my profile for the xB and look in my power hungry mods. You dont need everything that I have, but like I said, if you wanna do it right you gotta spend the bucks.

I had no problems when I installed my rail from Perrin other than having to cut that stupid fuel line guard. Also, anytime you change the rail you should change the injector orings anyways. Its just added security.

Yea, what he said...

Vito... You still in Vegas eatin dinner??? You never called back... LOL

^^^^^^^ :rofl: :rofl: :rofl: :rofl:
Yo, my bad Stuart, after walkin around for that lil bit and eating something I layed down on the bed and it swallowed me up for the rest of the night(the beds were ridiculous at the Wynn)...I woke up and looked at the clock and it was like 3:30 in the morning. I was soo ____ed cause I definitely wanted to get up and chill for a few. It was a crazy week though and I definitely was soo tired and shot from all the walking and partying.
We will get up one day soon though, Im gonna cruise up there soon before the holidays and check out the box cause I havent seen it since the major overhaul.

is fuel return system REQUIRE for TSI kit?

is fuel return system REQUIRE for TSI kit?
No, but if you didnt go with the extra injector setup which I dont think you did, then I would defnitely do it. I didn't use the added injectors either cause I was going to do a return line from the begining.

so upgrade fuel pump, rail and injector is not gonna do much as fuel return system?

A return line could only help. I guess its up to you if you wanna do it or not but I think that you went this far as to do everything else, it might make sense to just do the return line.

how much does it cost? and how hard is it to install?

well, figure about $100-$125 for the fuel line
about $160 for the Aeromotive Fuel pressure reg(I have one brand new in the box if you wanna buy that one...I bought 2 on accident through Ebay and never returned it)
about $100 worth of Earls AN fittings

Its not hard at all, if you were able to change the fuel pump, you can run the return line. You also need some zip ties or clips to hold the line tight up against the frame.

hmmmm ....

do i need to drill any hole?

IM me later so we could talk about htis

with that outta the way I guess i have to let you guys know that I enjoy driving togues...would being boosted be more a disadvantage or an advantage? I don't know anything on turbos, just that smaller one spool faster, and bigger ones spool slower....and...yeah. one more question...what are THE necessaties parts wise when it comes to boosting, I mean the stuff that you ABSOLUTELY need to purchase

hello people, I have a blitz boosted ECHO and my question is how does the car ecu get along with the Greddy E-manage? I have an S-AFCII installed but that is not cutting it because of the factory ecu. I am thinking of upgrading to the E-Manage Ultimate but before I drop the cash I want to know if our damn "too smart ECU's" will negate any positive effects here is my car domain addy for the rest of the ECHO mods.

hmmmm ....

All you need to do is drill one hole in the sending unit to put the bulkhead fitting in then you are set.

With your ECU you will have better luck...we have a different bit rate processor than you do, and ours is far more advanced which means you are lucky and we get sh!ted on hahaha. With the Emanage and the Map sensor for tuning you sould be alright. Have you tried pulling your EFI fuses once every couple of days yet?

what are THE necessaties parts wise when it comes to boosting, I mean the stuff that you ABSOLUTELY need to purchase

Well, obviously the turbo, manifold, intercooler, BOV, and some sort of fuel management(which is entirely up to you how far you wanna take it) If you only wanna run 4-5 psi then you will be alright with a simple piggy back, but I suggest anything after that you should highly consider injectors, fuel pump at the minimum.

i havent pulled the fuses but just curious what will that do?

from looking at picture of fuel return system it seems pretty easy.

my question is how does it work? to me it seems like its pulling left over fuels from fuel rail back into the tank... is it right?

and what is that black hose hooked up to?
http://memimage.cardomain.net/member_images/5/web/365000-365999/365461_31_full.jpg
from that unit (forgot name) 1 is from the rail, 1 goes back to sending unit, whats that black one?

And for the sending unit, I just need to drill one hole to put the fuel line in right? Do i need to connect it to somehwere?

Sorry about bunch of Q's....

Fuel return system does just what it says, its a constant flow of fuel from the tank to the rail to the regulator and back to the tank. Black hose is a vacuum line. The bulkhead that you drill into the sending unit is just the drain, so when you attach the bulkhead to the line your all setup for the return.
Hope that helps...if its not clear to you I will try to explain it better.

i havent pulled the fuses but just curious what will that do?

It resets your fuel trims back to normal. You are probably experienceing some bogging during boost then it kicks right in correct?? Thats the fuel trims trying to compensate for the boost you are pushing through the intake mani, totally erasing anything you tried to adjust through the S-AFC. Try pulling both EFI fuse and EFI relay and run it for a day...it will run a hell of a lot better I can promise you that.

If you need photos of how to do the fuel return, check out my site.. www.lastlookcustoms.com There are a ton of pictures in the photo gallery of the turbo install including placement of the fitting in the sending unit. If you have any ?'s, shoot me an IM on AIM.. Screename is LastLookCustoms

Ok, I found what was wrong with it.

S-AFC II was not hooked up correct.... stupid a$$.... :tap:

anyway I got the fuel pump, rail, injector, swapped S-AFC II to Greddy E-Management, and the spark plug.

Now it runs like its ment to be.

Thx guys for all the help.

CEL is not commin on and dang it feels good.... to be boosted...

what's a good boost pressure to run? i mean one that will make my car peppier

6 psi is enough to have a lot of fun.

were any new kits unvieled at sema this year as the rumors purported they would be?

what's a good boost pressure to run? i mean one that will make my car peppier

the blitz maxes at 10 psi

damn it!
my car wont start! when its cold!
I have to keep on crankin starter and when it finally starts.
I have rev my RPM at 2 for like min.
after that when i rev up high smoke comes out.
I am guessing it's because of the new e-management and since it's not been tuned yet... damn ____ suck!
Never going turbo again on any car..
next car is going to be mercede and wont do anything!

i have the same crank issue....it is from the fuel line set up.
it leaks pressure that would normally be held with a normal set up.

the fuel pump does not start pumping till the motor is cranking. takes a few seconds to get full pressure.

no smoke for me though....

The smoke is the oil pressure building up in the turbo...the T20 or T25 series turbos only like to see about 30-50 psi of oil pressure. As we all know, our cars put out about 80-100psi depending on load. What you need to do is put a oil pressure restrictor in between your oil feed line going to the oil filter block. Limit it to pressure I stated above and you will be fine. Dont wait too long to do this or you can eventually blow out the turbo seals.

Where and how much is oil pressure restrictor.

there are a few different websites...just type in oil pressure restrictor and they will come up. See if you can get a setup where you can add a gauge...thats what I did or you will never know how much pressure is going to the turbo

how do i know what the fittings are...

and which one is the oil feed line?

dude,
the fuel pump does not start pumping till you crank the motor....not just turn the key to 'ON' but crank...it is just like i wrote it...
it takes a little time for the fuel line to reach full pressure. then the motor will start up..

think of a garden hose. when you first attach the hose to the spiket the hose is empty.
when you first open the valve, water does not come out the other end of the hose....
it takes a little bit to fill up the hose so water can come out the other end....

Actually Dave, I think he is right. The reason why I know this is because when I put the 255lph in my car, you can here the whining from the pump when the ignition is turned on. Same thing with say a fuel injected bike. On my bike, I wait till I dont hear the fuel pump initializing anymore, then I will start it(only about 5 seconds). To answer your quesion Bomex...its the only line thats going to the oil filter adapter(if you have one). As far as size goes, I dont really remember...I actually have one if I can find it, but it doesnt have a spot to add a gauge onto it though.

don't think so vito...my pump does not pump without cranking the motor...

i know this from doing my fuel rail and injectors....had pinched an o-ring.
just turning the key to 'ON' would not presurize the system...
crank the motor and the leak showed up...(if it would pump in the 'ON' position, the leak would show up right away.)
the pump needs to 'see' the crank sensor reading something.

i do know that you hear other cars presurizing the system when you turn the car to 'ON', but not our car.

Yes...your oil smoking problem is definitley the oil pressure. You need a restrictor. Even after you install the restrictor, watch your oil level. I was going through about a quart of oil per week even after the restrictor. That could also be your hard starting problem. Maybe you are fouling the plugs because of the oil going trhough there. I am not sure about the fuel pump issue. Maybe that is why I wasnt getting any power to my pump with the key in the on position...If that was my problem all along, I will be so ____ed...LOL...

Thats where the installer pulled the oil line from ( I believe...not 100% if this is it)

so how do i install the restrictor?

I have placed them on order and its on my way....

wrong line...that is the oil return line....try again.
look by the oil filter....just above the filter might be a block adapter with a line coming out of that..

ok I went down underneat of the car again.

found 3 lines going into turbo.

it's kind of hard to see #1 line from the bottom view....


So can someone tell me which line is the oil feed line?

so i can put oil pressure restrictor on...

follow the lines from the turbo, where do they go to???

one of the lines is in the pictures in your prior posting. that is the oil return line (looks like #3)

so follow lines 1 and 2. see where they go and what they connect to.
one of them should go towards the front of the motor by the oil filter or starter.....

#1 GOES TO THE FRONT OF THE MOTOR.

SO IS THAT IT?

Hey Bomex, you called me a while ago and I tried to give you help on everything you need for your set up, but I guess the only advice you took was the E-Manage. You might want to simplify your system a little.

The entire basis of the fuel system is designed to run as a "dead head" system. The Scion fuel system is controlled by the factory ECU and our pumps do not consistently pump fuel all the time when the car is on. The factory ECU only pumps as much as you need (up to a certain psi). Running a return fuel line back to the tank will work, but you may run into many different problems that cannot be seen untill later.

Your fuel compensation "set-up" will hick-up every once in a while if you don't try to compensate the additional fuel by working with the factory ECU. The reason E-Manage works so well, is that it allows the factory ECU to send signals through the piggy-back at it's normal rate (as if everything is stock) to the engine. The E-Manage does not change the output values of the factory ECU to the engine. The E-Manage only takes in the reading of the airflow and throttle positioning from the ECU and compensates fuel by adding milli-seconds of grounding to each individual injector (therefore adding additional fuel). The ECU and the engine see eye to eye just like it was meant to be, and the E-Manage adds extra fuel under boost without the ECU knowing.

This is why E-Manage is such a great piggy-back. It's not like a S-AFC or similar units that trick the factory ECU into thinking that the air-flow is different than what it is. The Emanage allows the factory ECU to do it's job and then add what is needed.

You can try different setups for your turbo in order to get it running. Trust me, I've worked with almost every major turbo manufacturer for 6 months in order to find the most simple and effective setup. We've exhausted most methods in order to trick the factory ECU into boosting. In the end, the best way was to just get the E-Manage and spend the time on the Dyno tuning.

Don't get me wrong here, I'm in no way saying that your current setup won't work. But for everything you have, and all the problems you are encountering...

E-Manage, 310cc injectors, and dyno time, how much easier do you want it?

Good luck...

I am one step closer to closing in on the tsi, kit w/o the ems. I know about the fuel pump, injectors, fuel rail, fuel filter, return fuel line, all the monitoring guages, but am confused on which EMS to go with. What exactly will the E-Manage do? Does it only do the job of fuel? Does the E-Manage do both fuel and engine managment? Besides a wideband 02, do i need any other form of EMS. This will be a sucessfull instal, by a professional shop and the goal is to run no more than 6psi safely. I have even considered the Koyo upgrade as far as a radiator. Help me clarify? Lastly will the TSI FMIC be visible on the Xa? The more sleeper the better.

the xb has a turbo kit from greddy right? since the xb and xA run on the same engine code...I could use that kit right? aside from the intake right?

greedy setup is a.w.o.l(absent w/o leave) Good luck finding one. I belive that i cost to much to offer to the public so the idea was put on the back burner

Hey Steve...any word from F5 showing any interest yet??

I got a blitz s/c kit, but it came with a fuel controller for the 2nz-fe, anyone know if I could use that one anyway.
If thats a really bad Idea I think I want to go with TurboXS Dtec-fc for fuel management.
I dont think I want to run a return line, anyone know where I can get the in tank FPR that Dave is running?

Is this thread still alive? Has anyone noticed that Turbo kits. bla bla is now offering the emanage, injectors as a second option for ems? I am starting to warm up to this kit a little more. For those who have run this kit does that second option plus (out of pocket fuel pump, fuel rail, return line, radiator upgrade... sound like a better than first look glance?

I recently bought an xB with a prototype custom turbo installed. Got it for $13000. I posted some pics on a different forum and somebody saw it and told me that there was a post on that system on this forum and that alot of people criticized it because it didn't look professional. It still doesn't look professional, but it gets the job done. I'm not into showing my car, I just want a bit more performance than the stock. The original link to the forum was here: http://www.scionlife.com/forums/viewtopic.php?t=69643&highlight=turbo++pics

And here is my post on a different forum: http://www.toyotanation.com/forum/t110362.html

So far, I've re-added a catalytic convertor that was removed, but was still having problems with alot of carbon soot particles on the back of my xB. And when I dynoed the car, it looked like the air-fuel ratio was too low which told me I was running rich. The car came with an Apexi SAFC2 installed and after reading the manual I put the settings from 30-40% lower to see if I can trick the ECU into giving me less fuel...with the hopes of minimizing the carbon particles. I was able to also modify the settings for the Deceleration Air Upper Limit because at times when I came to a stop the engine would die on me which would be really annoying...anyway, it seems to have done the trick.

I think I will have to contact the previous owner to see if they can tell me exactly everything that was installed so I can see what needs to be upgraded or added to make the turbo function optimally.

Does anyone on here also have a dyno chart they can upload, I want to see how it looks like compared to mine.

get in touch with some of the guys that have allready gone F/I (do a search for turbo) It sounds like you have the TSI kit, but what do i know.

Naa...hes got the one off prototype that was done out in texas...it was a top mount turbo...I much rather would have had a top mount than how it was stuffed between my firewall...I burnt up some of that fabric that covers the firewall with my turbo

wow, when will there be quality turbo kit, or rather ems. Anyone have insight on AEM's. All i know is that its around $1,5000.

:lalala: Just had the TSI Turbo kit installed by AirPort Toyota in Vandallia Ohio. The install took about four days and there were a few tuning problems, but they were all worked out. The fun factor drive the XB has gone way up. Very little turbo lag, but has a slight hesitation when cold. I hope to get it on a dyno to get a proper tune. If you know of a dyno in the Dayton Oh area please drop me a line. I would recommend this kit and Air Port Toyota for the install
[/img]

I also Had a Borlo exhaust sytem installed, The twin pipes look great sticking out the rear and sounds great. Next step is install the projection lights and the leather seats.

The Turbo has been installed for a couple of weeks now, and here is an update. 90% of the time the system works great, and what a blast smoking Civics, Stratus, Corollas and TCs. But 10% of the time the system gets confused and I get a major bog during accelaration. The system works best when in the higher gears and it will pull hard. Problems occur when coming up thru the gears. I had passed on to the dealership (Airport Toyota) that the eManage system was the way to go and they led me to believe that was what they were installing. They installed the option 1 fuel managemwnt system which has problem with the XB ECU. So I am going to purchase the eManage and the larger injectors and have someone else install, plus have it tuned on a Dyno in Cincinnati. I will update in the next couple of weeks.

Even though there are problems, the turbo makes the XB so much more fun to drive.

Post some dyno charts when you get it tuned.

well, I am one of the latest to join the FI club here. I installed a Greddy turbo kit in my XB about 2 weeks ago. Everything seems fine and I was very happy with the amount of torque this little engine gained. Here are a few downsides to going turbo from my experience.

#1 the greddy kit does NOT come with instructions. It comes with Emanage, but no way to monitor or change the settings

#2 have a new clutch ready. The stock one will slip for SURE

#3 After continuous driving you will have a check engine light, VSC, and traction control light. All I did to get rid of that is pull disconnect the battery and reset the ECU.

If you are going to turbo charge, be sure to have clutch and bov ready because even though the Greddy kit is only 6psi of boost, youll get quite a bit of surge. The good thing is FI is not out of many peoples reach financially. You can go turbo safely for under $2500 easily.

Post some dyno charts when you get it tuned.

Here is a chart of my XB turbo from today. Lots of TQ. THe hp is not what I expect it to be but I am not too happy with the Emanage programming.

That curve is really jotty :nope:

First of all, I want to thank you for starting this thread. As our cars are still so new, any information certainly helps us all. My turbo kit has been in my car for over a month now and there are a few issues, some resolved and some others not, that I have been faced with. The car ran great for about a week. While taking a 4 hour drive/trip to visit some friends, my CEL, VSD, and TRAC like went on. The car ran normal and I was in the middle of nowhere so I continued. That happened on a Friday night. The next monday, I came to work and decided to put my car on the dyno to see what was going on. Oh, before I get into that, I completely agree that the turbo going there by the firewall is kinda stupid. The heat shield provided with the Greddy kit is OK< but I had to add some more heat insulation to stop the firewall material from drying. Anyways, back to the story. I dynoed my car and it ran very lean. At 5-6psi my car would run at 13.5:1 AFR at WOT past 4k rpm. The Emanage from greddy does not have air flow corrections to increase the amount of fuel going to the engine. What they did was just increase the duty cycle past 20-30% of throttle/rpm. I increased those parameters and the car ran a little better. Occassionally at light throttle the car would hesitate very badly. I am still not sure what that is. I am starting to guess that it is just the toyota ecu that controls the vvti. I just recently turbod an Elise and its doing the same exact thing.

I had a few questions for you simplyscion. What did you use to control the ecu? and did you have the low throttle hesitation that I am experiencing? Thank you in advance.

I used the Camcon wich was complete junk IMO. The ECU would overide the Camcon within miles and I was constantly left resetting my EFI fuses every day. I didnt experience partial throttle breakup, but more of WOT issues...my MAF was maxing out and causeing everything to go out of wack. I wish I still had the car sometimes cause theres so many things I wanted to try that I didnt get a chance to.

I thnk that is what the ECU is doing to the Emanage. It would be ok at first but the ECU would over ride whatever was trying to "trick" it. We dynoed a Lotus Elise with headers at 196whp. After a while, the ECU caught on and the dyno run produced 169whp. These ECUs are tricky. I was wondering if the ECU would notice the injector size difference also?

Hello...McFly...

Now that I have your attention I'm hoping that someone reading this thread knows anything about turbos and can explain it to me.

I know there's different stages...0, 1, 2...to what...who knows? Can someone explain what this rating means? And what is available for an xB?

And I know that there's different manufacturers as evidenced in this thread alone.
Any info on what manufacturers there are and the pros/cons of one over the other?

And approx how much should a turbo kit for my xB cost? I see a wide variety of numbers.

Sorry for just throwing it up here when I know that 'search' is my friend and the information is proably already sitting somewhere around here. I'm just looking for the short & sweet answer. Thanks!!!

Well CoreyAnn... Im not sure you will get short and sweet answers.. But I will try and make them that..

There are not really to many xB kits that come in stages.. The ZPI tC kits come in stages... Stage 0- just turbo and piping, it does not come with front mount intercooler, bigger injectors or engine managment... Stage 1- comes with everything turbo, piping, FMIC, bigger injectors and engine managment... there is also a 1.5 kit that comes with a bigger turbo..

Now I guess the Greedy turbo kits for the xB could be classified in stages..cause they offer 2 different sections like the tC kits mentioned above. The ZPI xB turbo kit comes with everything you need, they dont have stages yet.

TSI also makes a turbo kit for the xB and a few other companies.. But Greddy and ZPI will be the 2 biggest companies with most kits in the feild.

You will get a million answers on which one to buy and how much you will spend.. I think it depends on what you want out of it.
ZPI- more WHP, more sleeperish, full kit, more money, and less heat in the engine bay (due to where the turbo is placed)
Greddy- less WHP, more bling under the hood, does come in stages and has way more heat under the hood because of turbo placement.

Im sure I missed somthing..let me know if I did or if you have any more questions.. Were always here to help.

hey bro i wanted to ask you a question, if i put a bad ___ borla exhaust system, an RD Injen CAI and a Supercharger or turbocharger in my car, what would be the total HP after modifying it. and what do you think would be better for this car, a turbocharger or a supercharger?

Intake, exhaust and supercharger would net you proably about 120-130 whp.. so 30-40ish whp over stock, which will make an xB a heck of alot more fun to drive.. In all honesty a turbo is gonna net you the most whp for your car, no if, and's or but's about it.

Okay so I'll be honest I didn't quite read all of the posts here but I read most, and I make no promises that what I'm asking hasn't already been answered. I'm the happy owner of a 2004 Scion Xa and I want to supercharge it. Least I think I do, I'm not sure which is better supercharging it or turbo charging it. I love my Xa to death but for a... well a speed hungry person as myself it's just not quite there. And I'd like the rundown on the Blitz Supercharger Kit for the Auto Scion Xa. And if you'd like to suggest a better kit please feel free ;) As a note I was curious if you can run a NOS System with a supercharger?

You should check this thread:

Hopefully that willwork. Theres alot of crabbin and whinin and cryin on that thread, but I have personally seen blown_xa's car run, and it is quite awesome. When I saw it, it had a blitz supercharger and a zex 50 shot. He was running very consistent low 14's in the quarter with that. Also, he told me that he was still getting about 300 miles to the tank of gas, but had not put it through emissions yet. A very sweet ride indeed.

I think if I boost my xa, Ill probably go the turbo route. ProshopXB above has a turbo'ed xb and I hear its quite fast, but Im not sure of his dyno numbers. Proshop, what numbers you getting and hows it running?

Well unfortuantely my kit is off my car and for sale, due to some Finacial downfalls I had fall on me.. But when it was on the car it ran perfect and was super fast for an Auto. I never got a dyno done, but I have driven plenty of cars that are 140 whp or more and it was just as fast as these cars if not faster.. Fusionscion (Peter) has taken over the roll as being the ZPI turbo Poster child.. He has a 5-speed and is only running 6psi right now.. but will be getting a retune and be running over 8psi when he gets his dyno done.. This will truly tell what these kits are capable.. Which should be damn fast..

I recently just purchased an xb, so i'm pretty much a n00b to the scion world.
but after having the xb for only a week or so, I'm already interested in SC it.
But I was curious, isn't it difficult to have a SC on a vehicle with 10.5:1 compression ? I know the optimal ratio to supercharge is lower, such as 8:1, 9:1, etc.
this may sound like a pretty stupid question buttt, just curious.

You would proably run better and get more whp if you went with lower compression pistons.. But from what I have seen the SC is not effected by the higher compression pistons. So worst case you can put the SCer on and get lower compression pistons later if money is a factor.

Okay, so I'm thinking about getting a Greddy SC for my xB. Does anyone have any experience with this setup on a daily driver? Is it reliable? And I hate to bring it up again, but is it really worth it and noticable?

You might try PMing 808Customs or Rocket.. they both have had there SCer's on for about a year and would be best to tell you about it's reliability and noticable gains... A turbo setup will net you way more power, but might be more work then you want to put up with on a daily, weekly or monthly basis.

This might be a dumb question, but are there any oil lines or fuel lines that need to be tapped or rerouted with the installation of a Greddy SC? Can you keep your A/C with the Greddy unit?

To my knowledge there are no extra fuel or oil lines needed for the Greddy... the Power Enterprise's SCer requires an oil line.. but it depend on the type of blower.. Becuse of the type of blower the greddy is, oil line is not required... You can keep your A/C with the unit, but you will need to zip tie the large A/C line next to belts to the metal on the passenger side. This will ensure enough room for the SCer and its belt to move freely and not hit the line.

IM NOT THINKING ABOUT I AM GOING TO TURBOCHARGE MY BOX BUT I CAN ONLY FIND TWO KITS THAT WORK WITH THE BOX, GREDDY AND ZPI, DOES ANYONE KNOW OF ANYOTHERS OUT THERE? HOPEFULLY ONE WITH ITS OWN SEPERATE OIL RESEVIOR AS WELL BUT EITHER WAYS GOOD, IF NOT ILL TAKE SUPERCHARGERS SUGGESSTIONS AS WELL THANKS

Okay so for the longest time I was on the fence about going F/I of some kind and I'm a little torn at the moment. I've seen the Power Enterprise kit for the bB (I have a 2004 xA) as well as the Blitz kit and looked at a few of the turbo kits (Mostly the one at Turbo Toyotas) and the question I have is the 3k price tag really worth the gains? Don't just give me a 'yes or no' answer that doesn't help any I'm interested in reasons. The other purpose of this post is that I do have a 2004 Scion xA (auto) and I'm curious what the generally agreed "best" F/I kit is. Whether it be Super Charging or Turboed I want your opinion.

shishno !!! hows vitorville? c my fams moving back to cali after living 6 yrs in fla n leavin me behind:(, im at fiu and cant transfer yet so i was wonderin hows victorville since coicendently my fams moving there

anyone with experance with the power enterprise s c ....i have a 06..xb......this looks like the best route for me.....not sure

i've bought a turbo with ex. 38mm w/g. Any suggestions on where to put the turbo,under the car like zpi or behind the engine? If i put it behind the engine then i might wanna make a custom manifold. Help me o f/i gurus. :pray:

I don't have any first hand experience with the zpi kit, but it just doesn't seem safe to me to have it that low to the ground, I would say go where mine is, utilize he exh. manifold, maintenance should be easier for ya in the long run, plus it adds a touch of class to your engine bay lol.

um guys...i was thinking of doing this for my setup http://img209.imageshack.us/img209/1795/28032008204rv5.jpg . don't wanna put turbo below the car coz too close to the ground :P , anybody know how to uninstall the right driveshaft,do i have to unscrew the right absorbers to do it?thx

subscribed.. wanna read this when i'm not looking for specific injector info ;)

I had a couple of questions. I'm thinking about supercharging my xB and was wondering if i need the entire kit? I'm running right now with the TRD CAI, DC Ceramic headers and TRD Muffler. Can I just put the blower on my engine and keep my TRD intake and headers on the engine?


Thanks

from what i've seen you can...

you need to say which supercharger you are going to use. My SC can not use any CAI that was not included in the kit.
the exhaust stuff is fine for any SC...if you do a turbo, you won't be able to use anything you have now...

What's better for a manual '04 xA, a supercharger or turbo?

What's better for a manual '04 xA, a supercharger or turbo?

my two cents...a turbo is better for you.
I have not seen upgraded torque converters, as a turbo only makes boost when you press the go pedal...it will be easier on your tranny.
the supercharger is allways making boost and could put extrain strain on the auto.

thanks for the input. just another question for you, will downshifting be in any way harmful with a turbo? since the boost will go way up and you are slowing down...or will the wastegate get rid of it?

Downshifting won't hurt the turbo. All the wastegate does is regulate the turbine speed via controlling the volume of air flowing over the exhaust turbine. Downshifting will just open the wastegate wider, but the turbo will stay at relitively the same RPM and boost since the exhaust volume increases when you downshift.

Coincedentaly if you're in the market I do have a Greddy turbo up for sale. Just check my sig.

I can't believe I haven't seen this thread at all. Quick facts, i have a '05 manual xb w/ greddy turbo, mishimoto intercooler, custom intercooler piping, greddy oil catch can & b&m oil cooler. I would have had a greaddy bov, but the one i ordered was fake so i didn't have it installed. also right now i have the base map on the E-manage

i love the torque that i got from the turbo, but i didn't gain as much hp as i wished to have gain. the shop claims it's due to my clutch slipping out since it couldn't handle the power.

i do always have the CEL's on constantly and my error code is something along the lines of the rear O2 sensor - can't remember exact verbage

so my questions are:

did you guys have to replace your clutch with a stage 2 after installing the turbo? I know mine is going & i only have 76k on the car now so when i accelerate i go and go, then it just drops.

do you guys let the car sit in the mornings and run for several minutes to let turbo warm up before driving off? Do you let it cool down after driving on it? I do not have a turbo timer installed yet so I usually just sit in my car to let it warm up and cool down every day - anywhere from 2-5 min.

i want to up the boost from 5 to 8 if i can, so what would be involved for me to do that? i know replace the clutch is one & having a custom tune on the e-manage as well, but what else should I do?

has anyone had instances where you stomp on the gas, but the car didn't really respond? almost like it wasn't getting gas flowing instantly? this is hard to explain but sometimes in 1st & 2nd gear whenever i hit the gas pedal there is a hesitation then all the sudden the car gets up & goes.

i think that is for this post - don't get me wrong I love my turbo. it has made the car a lot more fun to drive (specially on the freeway), i love the sound (can't wait to get a bov) and love the looks when people see a box with a front mounted intercooler. so there is a lot of perks, but i have had some negative with it that i soon hope to get over. i am going to get away from the show scene so not worry so much about having a bad arse looking car, but now i want to make it a fun driving car

I toasted my clutch at 7k...really need to swap it out asap. The car will act so much better.
af for warm up or cool down...I don't really let it warm up, but I do let it idle while I close the garage, the just go easy with it till the blue light goes out. For cool down...I do the opposite. Stop punishing it a few miles from the house then a min or so idleing before stuffing it in the garage. I feel the idle cool downs don't really work if there is no air movement through the engine bay (ie moving on the road) if you are that concered about it...add a gauge for oil temp. Then let the car run for a few mins at the lowest reading.

thanks for the info. I am going to replace the clutch & hope that helps out & i may add a oil temp guage as well for added measure

has anyone installed the greddy supercharger in an xA?

I'm getting an injen short ram intake this week then in a few weeks i'm getting a magnaflow cat back exhaust. I want to get a turbo eventually but whats the best i should get? Both expense wise and performance.

Hey all...lots of great info in this thread...I am piecing together parts to boost my xA...and hope someone can answer a few questions for me as I decide what parts to purchase...please forgive me or at least give a link if these ?'s were answered anywhere else:

Is there is a Walbro 255 that fits in the Xa pump can?/ is it the same as the Tc pump can? Do I need 255?

What is the stock fuel pressure?

What is the stock injector flowrate?

and are the xA's map or maf based?

As with most questions, these will probably lead to other questions...so thanks for any help you give, and I will probably need more.

Four t2, blown_xA is probably as close as you're going to get on here for an expert on turbo on the xA. We really need to know what turbo size / HP numbers you want before answering your questions.

I can give you some basics though. With stock internals, the 1NZ is good only to about 150 WHP. The rods are notoriously week, coupled with a high stock c/r of 10.5:1, means a bad tune can cost you an engine pretty quickly. For a moderate-sized turbo, those sold in the kits, you're good for around 8 psi. At those pressures, you do not need to upgrade the fuel pump, on the injectors. The stock flow rate is 180cc I believe, start your tune by grabbing a cheap pair of tC 270cc injectors or out of a Celica, then work your way up if needed. The stock ECU is MAF based, you can add a pressure sensor to eManage blue, Ultimate and AEM F/IC have one built in.

FYI, so far I've ran a Greddy supercharger and a Greddy turbo, and hope to finish my Garrett 2252 build this summer, all in an auto xB. Currently will be on my 3rd motor, this one will be built.

Hey guys, i read through the 1st few pages and couldnt find a answer to this question. What is the most recomended plugs to run because mine are fouled out. And where is a good place to get them?
Im turboed @ 5 psi fyi.
Thanks in advance!
