    Hi guys
    I'm after some advice for what turbo to get in the future for my sr20
    Its kinda stock
    Apexi power fc
    555 injectors
    z32 maf
    Fmic
    uprated fuel pump
    R8 coils
    A Walton manifold coming probably bottom mount with external wastegate (because I can)
    No vvti
    kinda aiming for around 340 to 380 bhp
    But also to future proof it if I wanted more.

    First thought was
    Gt2871r
    Then I saw the gtx2867r
    Then I saw the g25-550
    I dont know enough to make a decision I no without the vvti I dont want lots for lag.

    Any help would be great thanks

    Hi Chris, am in the same boat as you so would be interested to know too. I ended up buying this book but am only half way through, there is a good chapter on matching a turbo for your engine: Turbo: Real World High-Performance Turbocharger Systems (Performance How-To S-A Design): Amazon.co.uk: Jay K. Miller: 9781932494297: Books when I get to the end I will let you know! :)
    When you say 'no vvti' you mean you did the VTC delete?

    for lets say 365 you want the Gt2871r
    I am also in the same boat as you and if you want fast response you want the Gt2871r, read things that it can handle around 400 but then you would need a pretty ideal setup etc.
    It isn't really future proof regarding 450hp isn't going to happen but 350 is more then enough in an s13/s14

    Gen II GTX if you want 350-400, the G25-550 if you want more.
