    With higher mileage you'll want to first of course start by making sure all of your maintenance is up to date

    The best bang for your buck will be a turbo back exhaust and a tune. There is a thread on first modifications that's stickied at the top of the forum. I'd link it but I'm on my phone. Sorry!

    Start off with a Cobb AccessPort, 3 inch turbo back exhaust, and a pro-tune from a good tuner. That'll put you at stage 2. After that it's fuel pump, injectors, headers and an up pipe to finish off a Stage 2+ car.

    Trans. on the WRX doesn't like too much power, though I'm not sure where that begins to be an issue.

    Keep an eye out for oil loss and check your oil level every time you get gas. It's normal to lose a little but you want to make sure you're not going through too much. You can get an oil catch can or air/oil separator to help keep it out of the combustion chamber.

    My suggestion is get a full turbo back, get it tuned, and see how you like it. Search around the forums and take in as much information as you can and decide what you want to do from there. Learn from other peoples success...and failure...and talk with a shop that does a lot of work on Subarus about what you want to do with the car. Ultimately, a good shop with a good tuner will be able to give you the best information.

    i got the oil and everything changed after i bought it, using royal purple synthetic as the guy who changed it suggested, he owns an early 2000 sti and has it pretty well modded

    i was thinking of going the "tactrix" route as im pretty good with computers since the accessport is pretty pricey

    not sure of any good shops in the pittsburgh area though, was looking online last night, but no luck as of yet

    I've never really heard of anyone doing those sets of mods after stage 2. Most people always keep the OEM header with basic set ups. The uppipe is already Catless and an aftermarket unit wouldn't really be necessary unless you are going EWG or making huge power. Injectors and fuel pump also won't really do much for a stage 2 car. That would only be necessary if you're upgrading the turbo


    But yes. Start with stage 2. You can use a tatrix cable if you're comfortable with it. The jump in power should hold you over for a few months :P

    yeah, i feel like i would be good with a tactrix as they are cheaper than accessports and would not want to splurge on a protune, nor do i know any places that tune subies in my area.....

    another thing i was wondering, i had already purchased an intake prematurely before researching enough and was wondering how harmful it could be or if it would be safe to put on or not?

    Completely depends. Injectors and fuel pump will keep your IDC down. I personally won't allow my tuner to go over 85% IDC. You lean out under boost and you're looking at a blown motor. Headers, specifically EL Headers, give you a nice bump in power as well. A stage 2+ car with the proper upgrades can make 350-360 whp. it all depends on the tuner and how healthy the power train is though. An up pipe will help out with spool as well. If you go with an EWG up pipe you'll hold boost better through the power band.

    I'd suggest tuning for anything that involves air or fuel on the vehicle. I've heard that some intakes have no negative effect on airflow but, personally, I wouldn't be willing to chance it. What kind of intake is it?

    You won't hit that on the stock turbo.

    I actually didn't take into consideration the OEM turbo on the WRX. I'm not sure what the OEM turbo is capable of for a 2007. That said, more fuel = more boost = more power. Long as the tuner knows what he's doing and the TMIC can handle it (which is something else that you might want to upgrade if you go for more power)
