    new member/owner has simple mods queston.

    hello everyone
    i just recently bought a 2008 WRX (my first subie and turbo). just like everything else i buy, stock is not good enough. ive read up on the BPV and several other minor mods but im really at a loss on where to start. so i was wondering where is a good place to begin? i would like to see about 275-300 whp. id like to hear more BPV noise but its not that important. i like what i see from Perrin and would like some feedback from people who have used Perrin.
    id like to get an after MAF tube, BPV,turbo inlet hose, CAI, and Access port, cat or axle back exhaust. im not looking to get crazy with HP but would like a little more than stock. so what advice do you have for me?

    Since you've listed dyno #s as a goal, what dyno are you going to be using?

    The downpipe is the biggest restriction, so replacing that with a freer-flowing unit (along with proper tuning) will yield the best gains as a first step.

    Downpipe, 09 WRX turbo, cat back exhuast + a good tune would get you close to what you want. A good CAI will let you hear the stock BPV and the Perrin BPV sounds better than the stock valve.

    I'd agree with everything sjcurtis just said, but I wouldn't spend money on the perrin bpv.

    The turbo is called the vf52. Any catback exhaust that isn't an ebay brand, and same with downpipe. Intake.. search around and post what you'd like to purchase up... there are a lot of opinions on intakes... but with a turbo upgrade.. and intake isn't a bad idea.

    Ok thanks for the replies. So it looks like the first step is to let the car exhale better. So would I be wasting time and money by installing the access point first?

    No. But if you can find a local tuner that's a better option. Access Port is gonna limit the mods you can install because the OTS maps are only compatible with predetermined configurations of parts.

    so im looking to do a VF52 upgrade, one piece down pipe, CBE, CAI, turbo inlet tube, BPV, boost control. is there anything else i should look at? this is just my starting point. none of this stuff will go on until next spring (and brought to a tuner shop to get it all dialed in). does any one want to take a stab at where they think my whp will be?

    I would think you should be looking at 300whp.

    Depends on the dyno. If you're interested in chasing numbers, ask the person tuning your car, as they'll know their equipment/abilities best.
