I currently have a T3/T04E garret turbo. The compressor is a 57 trim .60 A/R and is fine for what I need. My exhaust however is a .48 A/R 4-bolt housing. For me to get 350-400 WHP, I will have to run 20 PSI and race gas. A larger housing will allow me to make the same power with less boost. Can I simply buy a .63 A/R housing and bolt it on (providing it fits around the wheel) or do I have to make other changes to the turbo?

I'm not sure on the wheel size, but I believe it to be Stage 3.

Thanks guys.

as long as youre correct on the turbine wheel size, you can bolt the .63 a/r stg3 housing directly up.
