This is VERY false, I have seen well over 650whp through a stock engine, completely unmodified. SMR, I would really look into getting a divided manifold when you upgrade along with a divided turbine housing. The increase in power and spool is unreal. That thread I posted that s372R with a 1.25 ar turbine housing is spooling just as fast as the Full Race 35R kit that was on it before. Thats a 72mm non bb turbo spooling the same as a 61mm 35R!Originally Posted by YoshiFC3S
Just be easy on that diff!
