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?

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.

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....
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.

A. My AVIC N1 was stolen

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.

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.

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.

FI
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.

Whats your reccomendation for a decent kit thats out now?
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.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 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!!!!!!!!!!

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.

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 ****** 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.
