    Injectors and Tuning

    As some of you all may remember the story on how and why I have the set up in my 11' WRX, it's not exactly picture perfect....Rebuilt engine with forged pistons, head studs and cometic gaskets (the usual) and a Blouch 440xt...and that's it. Well I'm ready to throw a few more dollars at old girl and get the proper sized injectors, pump, better tmic (yes top mount), another 3" downpipe and get a pro tune on a dyno.

    Now the question for you guys who have the experience is what are the best sized injectors and pump for this application and the best tmic. Take in mind that I'm going to try and push for high #'s because I feel I have a strong bottom end to handle it.
    Also I'm debating on bringing the car 500 miles to Top Speed Motorsports in Atlanta. Does anyone have experience with them? With that being said, is there anything else I'm not thinking of? Don't want to bring the car that far for a tune and not be set up totally right.

    Thanks for any advice that you all can give!!!

    TSM is a top notch shop

    ID1000s (link) would be a great choice of injectors.

    You don't think 1000's are too much?

    Were you planning on E85 or anything like that?

    Processwest is generally regarded as the best go to TMIC. Top quality, and comes with a matched splitter.

    Top Speed is also a highly regarded shop in the Subaru world. Give them a call and ask the same questions. They may have a little more insight as well.

    Was thinking of going pump gas for everyday driving and e85 for the track.
    Starting to stock up parts now for the next tear down on the car in the fall. Just bought another invidia 3" dp.

    I am pretty sure that if you are planning on running E85 with an aggressive tune then you will actually want to go higher than 1000cc injectors.
