ok, tell me this then...

Ok I want to do 10 PSI I have been reading alot into all of the work and the pistons, valve springs, wastegates, intercoolers, T3-T4 turbos and etc. I have learned that 20 PSI is a little too high and I should stick around 10-12 so says my performance shop in town...anyways so if I chnaged out my pistons, injectors, rings, rods, and got myself a new fuel rail and a turbo timer I would be good to go right..because I know someone who can hook me up as far as the engine parts go....
