    I have a Blouch 16G-XT turbo and needed to upgrade injectors. My tuner recommended these for my 2004 STi. We're still working on the tune but so far, they work well. Installation went fairly easy, just have to get some of the power steering lines out of the way on the passenger side.

    Great injectors and great customer service 1 year ago
    mikeforcina2495328
    These injectors are great, were more than enough for my stage 2 lgt. Gives you lots of room to work with safely. Had one faulty injector but the guys here at rallysportdirect helped me out no problem with setting me up with dw to claim another one. Can't beat a 3 yr warranty.

        A:  850cc injectors will support up to approximately 440whp on pump gas without maxing out and these will work well with a GT3076R turbo.
