Need help on weather or not to buy... I got him talked way down on the price, this will be my first subaru and first car with boost. I have built many hondas, all of which are n/a and my last build I was able to get 218hp to the wheels on a gsr motor. Anyways, I wanted to know if this car seems like a good buy. Is 18 psi safe on what looks like stock internals? Thanks for any help in this. 02 Subaru WRX. Clean
