    Rough cost to hit 300+hp in a 2012-2014 wrx

    Not a mechanic and am trying to decide what to do. I was looking at a used sti, but everything points me in the direction of walking away from it. I know I can buy a new wrx for 26k roughly, and was wondering how much money I would have to sink into it to obtain around 300+ hp safely. Im guessing the price of this can range pretty widely depending on parts, brands, do it yourself, or have a pro do it. Just looking for a rough guess on cost range. This would be more of a casual project car, garaged, and drove every once in awhile. As I said I am not a mechanic, but wouldn't mind learning and working on it myself. Unless that is all together a bad idea being as I have no experience working on cars in depth. Thanks

    $0 if you do your research

    $40,000 if you don't do your research.

    Are you talking about hp, or whp? If you're just wanting 300hp you should be able to hit that with just a tune. Stock Subaru has the car listed at 265hp, Cobb stage one tune advertises 13.5% hp increase, a custom stage one tune should put you over 300hp by Subaru's standards.


    So it depends on what tuner you want to use and how much they charge. You're looking at between $300 and $500.

    Either the 2009+ WRX is underrated from the factory or the 2008+ STi is overrated from the factory because both put down about 225-235whp in stock trim.

    I can make a dyno plot for the OP that will read 350whp on his stock WRX.

    Well they can't just tell people the WRX makes the same power as the STi (even though they have the same size engine/turbo). Otherwise there would be even more people questioning why get the STi.

    Reliable but powerful 2012 WRX mods
    read through my thread, my beginning goal was around 300whp. I received a lot of good feedback and did a decent amount of research also

    Chasing numbers is always a good way to spend a lot of money.

    $1500 should be plenty for you to hit 300whp. Get an Accesport if you want, catless downpipe, ebcs, intake.

    Catless DP, CAI, cat back, aftermarket TMIC and Pro tune should put 300 to the wheels.

    Both would make it easier.

    Without specifying what dyno you want to hit your "300+hp" on, no one can help you.

    Read kdeitrich's thread. This subject was beaten to death. There are variables....like EJ257 said, it largely depends on the dyno. You also have to take into account climate and altitude variable, yada yada. Imo, the safest way to make that power reliably is to set up your car to run E85 if that's an option in your area. I put down 301whp/335wtq on a very safe and conservative tune this way. I skipped the cai and catback for the time being because I reached my goal without them. End cost was roughly $4200. I also did my research, communicated with my tuner, bought quality parts, and put in wrench time as opposed to paying for part install.
