    To add to your statements, I'd say the turbo inlet is worth replacing with an aftermarket version if the stock one cracks (as it's prone to do). The newer cars are also prone to intercooler cracking at Stage II (and sometimes even stage 1). For the 3G cars, I would reserve a budget for a new TMIC and retune with any stage II modification, unless the OP decides to replace it along with the downpipe.

    I've thought about this a bit.

    You could do nothing at all and expect the car to last at least 200K miles with proper maintenance according to the schedule. If it doesn't, you could consider never buying another Subaru (I certainly wouldn't).

    Or, you could switch to a larger radiator, larger oil sump, silicone hoses for air and water, and strip the chassis down to metal so that you can seam weld under argon along every spot weld. You could then expect the car to last 200K miles with proper maintenance according to the schedule. If it doesn't, you could consider buying another Subaru (I would).

    Your call. If you need higher cooling capacity there is Koyo and others that make interesting Al radiators (see other threads). I'd not mess with the oil sump if the pickup still works (yours does, you'd know otherwise) and I'd go from there.

    Is DP, CAI, and AP v2-3 all I need to go Stage II?

    Cobb map notes call for a turboback exhaust and an accessport with a stage 2 tune. You could go opensource tune (tactrix cable and laptop) and just get a downpipe.

    Map + downpipe is much more direct, less costly, and should give you the results you want. Shop for a map. Cobb is only one option. There are others.

    Single time tune costs almost as much as a AP

    Right, a top dollar pro tune on a dyno would be a bout $500. But the AP is only hardware, if you want a good tune personalized for your car then you have to shell out more on top of that; and by then you've limited your options as far as tuners because not everyone tunes using an AP.

    But that's not what SD is saying. TurboXS, TorquedPerformance, Vishnu and many others make maps, or you can get a good email tune from WTF tuning or from Phatbotti tuning, or one of many other excellent email tuners from around the country for about $250. Borrow a tactrix cable from someone in your local subaru club to load the map and record some logs, or buy one used for about $150. There's tons and tons of options out there.

    But unlike the Cobb OTS maps, it would be custom-tailored to your car, and you'd have direct contact with a local tuner should issues arise later.

    GREAT thread. I learned A LOT. Thanks guys.

    @Rambo, I've seen you around here and you seem to have a lot of knowledge. I'm looking into buying a project bug eye in late spring and only recently bought my first Subaru so I'm not really experienced with their set up (Former Honda guy, last winter and my Saabaru 9-2x converted me lol) wondering if I could pm you questions when setting up my build?

    Shifting Lanes, Zax, and EJ257 would be some good people to PM as well.
