ISR turbo kit questions

[dmk477]

Hey fellas, I've done some digging and found some older threads with mixed reviews on the ISR kit. A friend of mine has recommended the kit and says many of his friends run it successfully, just looking for some more opinions. I'm looking to make 3-350hp, really hoping for 350 but understand that is pushing the engine quite a bit. ISR "claims" the kit is capable of 380, but are these numbers realistic? I was also considering leaving the factory manifold, just going a bigger turbo and the other supporting mods, and seeing where that could take me. Will the factory manifold support that type of power? Any help is appreciated.

1. You got a sr20? or replacing this turbo on a ka-t
2. Yes you can hit 350 provided you have the supporting mods and tune

Sorry, yes I’m running a sr. How long have you been running the kit?

I've been running the kit for 4k miles. The only issues were due to mistakes I made, the kit has been flawless.

Good to hear, thanks for the feedback.

I have this on my KA and it's good. The only problem was with the turbo creeping, but I fixed that with a boost controller and porting the internal wastegate. This only happened because of my straight through exhaust though. The manifold should be good for how much power you want to run. I run it at 8-10 psi and it makes more than enough power for drifting.
