my name is Alex, am from cali, am 17 years old. i owned volvo 740 turbo, surently own a 97 bmw 328i, am getting wrx none sti soon if everything is going to be ok. i had a turbo charged car so i know know about boosting the car but its a new world to me : wrx. everything is new to me. i have some little questions, whats the stock for non sti 2002 wrx boost? and what is the maximum boost can be raised for a stock motor? (hks intake, no catalystic, performance muffler). do i have to do something with the fuel delivery? and how many psi i should put out(under risk) to run at least 13.5, or if more, to even be close a little bit to sti? thanks guys!
