    2011 wrx build thread 325awh at 351 torque STOCK turbo

    I just wanted to share my build off of my 2011 wrx. All of the work concerning the actual build has been done by IAG and i am more than happy with the outcome. IAG will be doing much more work for me in the very near future with my wrx.

    Build Reason:

    The reason for my build was ultimately do to a negative result of low oil in my wrx that yielded very bad results to say the least .

    Prior build history:

    Prior to this build i was a simple stage 2 car running Cobb stage 2 (catted downpipe by perrin, AEM CAI and a nameless axle-back muffler delete set-up)

    Quick recap of the "bad" moment:

    Driving down I81 during the first snow and the car shuts off next to an 18 wheeler forcing me to pull off and wait for 2 1/2 hours for a tow back to my house.

    The Build start history:

    I was debating on what to do with the car and where to take it to. After calling multiple shops and much debate on the expenses that would soon take place i went with IAG. I went with IAG after talking with Drew and Rick over the course of a few days. I felt much more at ease after dealing with Drew and Rick from IAG and i was sold. I had the car towed to IAG after it sitting in my garage for over a week. Over the course of a few weeks/ a month i had gotten funds together to start the initial process of diagnosing and taking things apart. I knew that they were extremely busy at the shop. I basically had the car towed and let the guys have at it. I called very very few times as Drew and Rick were quick to call me with updates and new findings. As time went on, my parts list grew and grew as i kept adding on goodies to ensure a strong foundation for a proper build for future modifications. These decisions were based off of the excellent help and direction help of Rick.

    Destruction findings:

    The car ran low on oil with no real warning signs. I ended up spinning a rod bearing in cyl 2 and cyl 2 piston had a ringland that simply fell apart upon inspection, the rod was obviously bad as well.

    The parts list for the build

    Top end:

    GSC Stage 1 cams
    Springs, retainers

    No actual head work as of right now other than the cams, springs and retainers

    Bottom End:

    Manley H Beam rods
    Manley pistons 99.75mm

    Cylinders obviously machined to fit the pistons

    (Race bearings)

    Heat treated crank


    Walbo 255 pump
    ID 1000's


    Perrin Catted DP
    Nameless Axleback muff delete
    IAG Un-equal length headers
    IAG Up-pipe
    Perrin Turbo inlet




    Perrin TMIC


    Stock turbo (for now)
    Tial 38mm EWG (external dump)

    Oiling system:

    Killer B Pick-up system

    Boost Control:

    Grimmspeed EBCS

    Odds and ends:

    Crawford Air/Oil separator
    Air pump delete
    All race bearings

    After having the car tuned at IAG the results were not what i had expected. I was expecting numbers from 280-MAYbe 300 being as i am on stock turbo.

    The numbers are as follows:

    324awhp at 351 torque (uncorrected)

    The car is very fun to drive! AND i am glad i went with a set of cams as they REALLY helped out a lot in reaching those numbers.

    My next mods are as follows:

    Bigger turbo and STI tranny swap. My next goal is to hopefully be around mid to high 400's with a bigger turbo (i was thinking the 3-xtr? open to suggestions)
