Turbo

I put a turbo kit on a stock eclipse GS 420A engine and how much boost and you put on a stock engine? Garret T25 turbo.

Also how much hp can you push on the stock 420A engine before having to replace the clutch, crank shaft, flywheel and what not?

Re: Turbo

You can boost around 7-8psi. In order to run more boost you will have to build the motor with forged internals. You dont need to worry about the stock clutch for a while.

Re: Turbo



Yeah, you could boost to 7-8, but I'd keep it to 5-6 until you build the engine. I like to stay on the safe side of shit.
