garrett t3/t4

o.k and other than the down pipe do i need a boos controller different adapter for my air induction and for the stock intercooler?

and somebody knows how can i set the turbo psi and how much power can i really get with out changing rods and pistons just the way it is?

take it to a dyno and find the efficiency range for it. power is dependant on a lot of things, you can't just say "you'll get x amount"
