dear companies who make turbo kits,

ok fools, listen up. i want to be able to buy a turbo kit for my xB. i've had my car since june 6, 2003, and companies have been promising a turbo kit for the scions since...oh june 2003 or so. so where is it? and i'm sick of all this "we're still testing" BS. you guys have been testing for almost a year now. let's see some kits.

and none of this "it's almost done" crap, either. we know it's almost done. i could put together a kit right now, but i don't know how to deal with the ECU stuff. and that's probably everyone else's problem as well. yes, we've all seen the prototypes, heard the rumors, seen the pictures, but no one sells a kit that can just be purchased and installed. or do they? if so, let me know. i'm not saying i will buy one or anything. i just think it's about time that a kit is released. ok, i was joking. of course i would buy a kit. so would a lot of people. so where it is? this is getting crazy. a supercharger kit would also be cool, i guess.

also, i'm worried about how weak the 1NZ-FE engine is. boost would certainly be minimal. maybe a company could come up with a nice, simple engine upgrade kit to beef up the components a bit. maybe new pistons, rings, rods, valves, slightly more aggressive cams, and maybe lower the compression ratio a little. i don't know. i just made up all that stuff because i don't know anything about cars. but i do know i want a turbo kit.

thanks,

eric m.

I think you answered your own question and you don't even know it.. The 1nz-fe motor was not designed for high performance in mind... quite the contrary. Toyota does not make motors for performance. Putting boost to the 1nz-fe is a whole lot harder than you imagine. You have to make certain everything fits, works right and most importantly... does not blow the motor up. Look at how long it took Magnussen to design supercharger for the Matrix/Corolla. Alpine developments was designing a turbo for the Corolla as well but ran into all kinds of problems with the 1zz and the Toyota ecu that it was deemed not a good idea. It is really easy to sit at a keyboard and complain about the lack of a turbo, but just try putting one together yourself and we'll see you in a year or so and see how far you've gotten... My guess would be that you either built a turbo for your car and blew up the motor or you have a bunch of parts sitting in your garage and not in your car.

Sorry--but I think we all pretty much know what you just said...especially Eric.

And if the Supra Motor isn't made for High Performance...I don't know what is.

That's too broad of a statement dude...Toyota makes good motors period!

Hey eric...what are you talking about--SPY already has TWO versions of the turbo out, remember?

:roll:

I've been waiting just like you have man...this is killing me.

And if the Supra Motor isn't made for High Performance...I don't know what is.

How many Supras did Toyota Manufacture last year? This year? None...

Toyota builds there motors for maximum reliability and not maximum power. The 2zz motors in the Celica GTS and the Matrix XRS are week and can not take boost like the earlier 3sge motors can. Toyota makes their motors to last the test of time not the race track. Toyota's goal is not high performance but reliability and longevity.

hey eric. if u went to greddy, showed them the money and told them to put a turbo on.. do u think it'll happen?

NO NO, I agree with Eric. There should have been a turbo kit that is CARB legal or even a Jackson racing super charger! The honda Civic was not a strong motor either yet, there are modds for days on that dam thing and I am tired of it already. Where's the turbo. :shock:

Well i hate to say it but i guess we have to wait... I would buy the blitz but not enough money. Rev hard is my second choice, but they have been "testing" for the last 5 months...

2001rolla..

TRD S/Cs area available for just about every current Toyota engine available in NA. TTE developed an S/C for the 1NZ-FE, TRD Japan developed a T/C for it, and they run the Vitz cup (BIG racing tournament). In fact you can find TRD websites that link to all the necessary equipment to make the Vitz race-ready.

I think Toyota stands behind their cars as both daily drivers and performance vehicles alike.

hey eric. if u went to greddy, showed them the money and told them to put a turbo on.. do u think it'll happen?

Actually I had a chance to talk with a couple of people with greddy at IAS last week, and the greddy turbo is pretty much done. Their only delay is getting someone to manufacture bigger fuel injectors for the 1NZFE. They can't boost over 2 pounds, not because our motor is weak or because the internals cant handle it, but just because of the injectors. The good news is that they are making an amazing amount of power from those 2 pounds...about 20hp, so with some decent, yet conservative boost, the numbers might not be that bad.

One thought that I had is to make something similar to a nitrous wet kit, minus the nitrous. What if the existing kit was put in place with a WOT sensor triggering an extra fuel jet into the fuel rail, rather than all new injectors? Does anyone know of this being done? I think that for most cars its no big deal at all to put in larger injectors but if they simply are not available, this seems like a feasable option...

Here's a pic showing the break down of the TRD Japan T/C components taken from http://www.trdparts.jp/parts_vitz-turbo.html

4. Injector (capacity rise)
5. Fuel pump (capacity rise)
6. Intercooler (supercharging efficiency rise)
7. Intercooler duct (cooling efficiency rise)

9. Water cooling type oil cooler (cooling efficiency rise and engine protection)
10. E.C.U. (Setting for turbo)
11. Box upper (form modification)
12. Under cover (oil return section protection and aerodynamic improvement)

Well, hopefully Greddy can get something put out soon...because I am itching for at least some glimmer of forced induction on our cars.

So far I've heard of Greddy, Rev Hard, Toyomoto, SPY, Blitz...

Blitz unit is out and ready to be purchased I think...at least i know DibujoB has one on the white xB they've got over there.

Nothing really as far as real world personal stuff with the others though...I'm not really sure what the exact problem is, but i guess if we've waited almost a year, we can wait a little while longer for Greddy and their problems with the injectors.

With upgraded internals--I do think the motor itself is capable of near 170-180 hp...but who knows, that would be sufficient for me, as long as we have beefed up internals to allow that to happen safely, and at the cost of about 3000 or less.

it isn't an STI but I'm a family man so I'll take the 2psi...I just want that blow off... Bwahahaha! :twisted:

And if the Supra Motor isn't made for High Performance...I don't know what is.

they not produce the supra, but they still have the 2j series engine in the lexus and the v8 they make has a good performance

:cry:

ok you guys have some good points but let me clarify a few things.

i do not want to go to a company and beg them for a product which hasn't gone through proper design and testing. in other words, i do not want to be the prototype car.

i do not want to order a turbo kit which is made for a japanese bB with auto trans. i don't think the ECU is the same and if it was, people would be importing them and selling them already.

i know the 1NZ-FE motor isn't hte strongest, but i think it can handle a little boost. toyota makes excellent motors. and not to be rude, but the blanket statement about how toyota engines aren't meant for performance just sounds ignorant. toyota makes excellent engines for formula 1 racing as well as many other forms of motorsports which require remendous abuse. the toyota rally car had an excellent 2.0 liter turbocharged engine, and their trucks are awesome as well. as for consumer cars, the supra engine is amazing. they even used parts from it on their new V6 trucks. we all have seen supras that make over 1000hp. how is that nor performance? sure, they only do 12s in the quarter mile, but that's another story. :)

anyway, i think once someone figures out how to get around the electronics of the xB, turbo kits will be a lot more of a reality. and don't get me wrong, i know the actually components are easy to get and make. for anyone who has added a turbo kit (like a drag kit on a honda) or built a custom turbo system for a normally aspirated car knows that making the piping and fitting the turbocharger is not hard. the xB actually has a nice place to put a turbo because the battery is right there and can be moved or relocated. an intercooler may or may not be needed, but i would at least have a small one on there. everything will be small actually. small turbo, small wastegate, low boost. but even if you can squeeze 30% more power out of the engine, that is a significant improvement. i mean, i have the spfr intake which only adds 1hp, and it feels a lot faster than stock. imagine 30hp!!! wow.

so if any companies release a sellable complete turbo kit for the xB, please let me know. yes, i know it is not easy to come out with a complete kit that is reliable and works well, but it can be done. a lot of money can be made here.

our cars make 108hp. to the flywheel. but i think they have potential. they only weigh around 2400 pounds, so adding 30hp makes a big difference. try adding 30hp to a 3400 pound car like a wrx. the results will be significantly less impressive.

eric get it right 1.42hp lol

I can sympathize with Erics frustrations. It does seem like those companies are taking a long time. Although, I don't have the money right now I would like to see some more progress. I know there are a lot of people who do have the funds to hook up a T/C or S/C.
At least Blitz has got the ball rolling. Hopefully, them producing a S/C will help the other companies get to moving on their projects, whether it be other S/C's or T/C's.

I'm sure the Toyota Team Europe S/C is readily available, and to my knowledge, the ECU specs for the European Yaris 1NZ-FE should be the same for ours here in North America.

reading these threads keep making me have scion withdraws and i get depressed that I bought this damn thing...150hp :lol: boosted, what a joke

I doubt people are gonna push over 12-14psi on the stock internals, let alone 10.5:1. But the final CR #s would be pretty high even at that low of boost.

And if the Supra Motor isn't made for High Performance...I don't know what is.

Depends on the motor. The xxx-GE or xxx-GTE motors certainly were built with performace as the primary consideration. A motor with the xxx-FE extension will have been designed with fuel efficiency as the primary consideration.

Please hang in there were almost done with the kit testing. I've been at all the California shows and some Vages shows in the Past two months, and I will be at more. If you would like to see this kit in person you are welcome to come to any show you like. You can also see me at some scion meets in So. Cal. If you would like to see what shows I will be at please send me a PM. Trying to get to the dyno, but they are closed for the holiday weekend!

here you go, greddy turbo kit, 100HP increase, lol

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33742&item=2480647414&rd=1

how are these people selling this kit if greddy has not even put out on the market yet,sounds like a scam to me

most likely... 100HP increase is not likely either.

I think that one of the problems is that Toyota rolled the Scion brand in California almost a year before the rest of the country got them. So, us So Cal Scion owners have been itching for forced induction for a while. My guess is that most companies are not making the Scion a development priority until the market has expanded a bit more. They don't really care that California Xb and xAers are getting impatient.

When manufacturing any product a company must utilize economies of scale in order to maximize profits. This means that they must order and manufacture a certain amount of parts to keep costs down. No sense in doing that if the inventory is just going to sit around and tie up cash flow. So, I'm assuming that when developers get a sense of the Scion market on a national scale they will start popping out aftermarket parts like mad. People will make anything that they think folks will buy.
