TTI turbo Kit power limits? The setup is
C5 vette
402ci LS2 motor (SLP) 9:1:1 block
6.0L heads ported.
TTI stage 1 kit.
One of the builders said the turbos are the same as the incon ones? And this setup will make over 600rwhp!
If this is true this is better than the Incon kit?
Anyone quess the power numbers and any idea what those turbos can do!

. Also, FWIW, I know for a fact that King_Pin has the "standard" .64 A/R exhaust housings. Thread Starter

WOW.but Sounds low power numbers for forged motor,stageX,meth,and75shoot. Sorry,Not trying to sound like a *******. but TTI says on the site it makes 500rwhp on a stock motor.
In your opinion can the stage1 make high 600-700rwhp with this setup only.
And does anyone know in the turbos are the very same as the incon kit? I see it has a water port that isn't used

You are going to choke the crap out of a 408 with a TTi stage 1 Vette kit. People where having back pressure issues with that kit on engines smaller than that. If you want that kind of power ditch the stage one and go with the stage X. If not you are going to try and band aid a turbo on that car and you are never going to be happy with it.
Flynbludream is 100% correct. That kit is not designed to move the exhaust of a big cube engine. That package will create tons of heat. That kit is maxed out with a 346 as it is. BTW, the TTi kit WILL make 700rwhp but it will have blowby in the cylinders after awhile because of the restrictive design. I would not go over 600rwhp with that kit for RELIABLE power and I would stick with the stock cam.

Good Luck in whatever you decide... lots of advice and choices out there

Thanks guys for all the great info. This is my friends project. And to say the least he is in way over his head and is only going with what different shops say. And I have told him time and time again he is doing it wrong. A 9:1:1 short block with huge ported 6.0L heads he will have 7:1:1. And they say turbo air flow maps mean "nothing" keeping the heat down and stock compression is all that matters, so the small turbos can still make 600-700rwhp. 
But what do we know right!
