    Cobb stage 2 turbo back exhaust would be a good investment. Along with giving me a little more power.

    Heres the real deal I want my little car to push around 300+. What do I need to do. Like I said im new to building up a little engine thing. If it was a old mustang or something I would know what to do. But with this little car I dont even know where to begin except for new exhaust and a intake. So if anyone can help me out I would be in debt to ya'll.

    You want 300+...BHP...WHP...TQ...????

    Either way your gonna need a bigger turbo, beef up your trans and a good tune.( + supporting mods)

    Search "300WHP" or what ever number your looking for and see what comes up. Many people have posted with very good info on how to do so.

    Good in what way?

    They are only good if you need them to hold more boost. But for stock or near stock application's they are useless.

    If you really want a bov, keep an eye on the for sale section. People are always selling them after a few thousand miles because their car runs like crap. Your engine will run rich inbetween every shift, causing backfires and engine stumbling. Bov's are only required when you're running 18lbs+ of boost.

    If you're lookin to get into the 300hp mark. Not only do you need to upgrade your turbo, injectors, fuel pump, and intercooler, but you need to upgrade your brakes and suspension. It would be real scary having all that power with sloppy suspension and poor brakes.

    BOV's ARE good for the turbo. What people don't usually explain, however, is that the WRX comes stock with a BOV that recirculates the air back into the intake system. Most aftermarket BOVs are the bad news. Reason being (vague crappy description) is because the ECU is expecting the air to be replaced into the intake system between shifts, and thus when you get back on the gas it matches that air with fuel. The ECU doesn't know that the air is being blown into the atmosphere (with the aftermarket) so it will add fuel for air that isn't there after a shift, causing the car to run rich.

    There are aftermarket BOV's that recirculate the air into the intake system, but unless you will be running over 20 psi, you don't need one.

    Any corrections to my crappy description are welcome
