I am planning on doing a turbo build with my 01 celica gt. I am thinking about getting the MWR turbo kit with a powerfc pretuned and I will be getting a better clutch aswell. I am wondering what I would need to do about exhaust, connecting rods, and valve springs. Keep in mind the connecting rods and valve springs are brand new in there and are not old. I am new to turbos but did build the engine myself so i have knowledge in that.
also what kind of hp and torque gains could i expect with ~8psi boost.

Thanks
