Well yesterday I was leaving the show down at Carlisle. I was only running 10psi, normally I run 7, I hit the gas the car spolled up and then the car shuttered and I heard a weird sound form the engine bay and the boost dropped to 0. I pulled over and checked over couplers, bov, etc.. Then I checked the exhaust and I found little bits of something. I found out when I got home that the exhaust wheel had destroyed its self. So now its time to get a new turbo.

Wow that gives me great confidence in my stock RB20 turbo. Stock boost is 10-11psi.

Well good thing the next purchase is Nistune and a small holset turbo.

Im looking at the HX30 which should be capable of about 375-400WHP. Or a EVO 8 turbo thats good for the same range, but it needs an adaptor plate. So small but not that small.

GL with your build though.

I just wish my car ran in the first place ><
