5S-FE Turbo Project, First things first... Options

[Supersprynt]

I'm planning on putting a turbo into my 94 GT - and im thinking CT-26 outta a supra and maybe if i can fit the intercooler, that too. Plus high compression pistons, new (possibly kevlar) clutch, but I think im missing something...keep in mind im not set on this CT-26, but the kit from Buillen or whatever boosts about 45hp pushin 5psi, not too much considering its 2500 dollars. Ne body ?

Please check out my post at http://www.6gc.net/forums/index.php?act=ST&f=4&t=662 TurboCharger project from scrap for Do-IT-Yourself

Please read the whole post.

Also, please do some reading on tunign and so on.

1) Your compression pistons would be adequate for turbo.
High compress. pistons are good for NA. Even then, your head is not geared towards performance, so you might have some detonation going to 11:1 and above.

You normally use low compress pistions 8.0+:1 and up on turbocharge engines.

The CT26 is good. remember that the supra is twin turbo's, implying small turbos to start with. That is why you have the same turbo in the GTFours.

Twin turbos almost mean HP= Nx(turbos power @ 80% efficiency) where N is the number of turbos.

eg. I am not sure on the power out put on this turbo. But here goes.

The CT26 is capable of 300HP at and unreliable state. So let say 80% of its efficiency is 280HP. That means that in twin turbo applications, like in the supra or any car that uses a similar turbo and where are the condition are met, the total engine output limited by the turbos in this case (supra) maybe 480 -520HP on these stock turbo.

Again, I am estimating here, knowing nothing on supra power capabilities on these turbos.

You will need some piggy back components like Apexi SAFC and so on.

Again, read my post for such details. You can do alot more HP with that turbo. If not get the turbo specify on my post. The only problem is the engine beign able to handle it.

Good luck and I look forward to see what others have to say who have been running turbo celicas above rated stock output.
