Have you priced a turbine housing?
You should be able to swap it for a tighter unit and get the results you want.
My original turbine housings were Turbonetics T3 Stage 3 with .68 A/R. They were so tight the engine couldn't pull more than 4900 rpm on the dyno. I stepped up to Stage 3 .96 A/R turbine housings and kept the same Stage 3 wheels. I have been happy ever since.



So your saying I can just find a T4 housing with a lower A/R and swap just the housing and not the wheel?
