hey man, i see youre in jersey what part? and these cars are capable of more, BUT you need all the proper bolt ons and something to tune with (ssafc or unichip) to up the boost. most guys run up to 10psi on a stock engine. some have run more usually 12psi on a stock block but thats about it . everyone will recommend going forged if u plan on pushing the boost up even higher. these engines arent the strongest, but these cars overall are fun to drive. im currently running 9psi untuned for now until i install my ssafc which ive been dreading doing the wiring. but once its wired in ill up it to 13-14psi. plus if u look at my sig, mine is far from stock.
