    T28r/tubular manifold sr20

    I'm looking to upgrade my turbo to a t28r and buy a decent tubular manifold that won't crack immediately as soon as I have the money.
    Where would people recommend for the turbo and what manifolds are good??
    I have spoken to apw already but would like to see what other options there are??

    Here's a picture of me on track at Combe for no reason

    how much are the APW ones?

    t28r is no real performance upgrade to a regular t28 just spools a bit sooner

    You can drum more boost with the t28r and together with maf, 555 injectors and a map out should gouge me a little bit more power. I can also run the t28r as the car is until I can afford the rest of the bits.
    Apw quoted 525

    From what I can remember there are three variations for what people call the t28r one is rated at 280 then 330 then 360.
    From what I have read; the one fitted to the early s15 is rated at 330 by garrett my car has the s15 turbo I have a rr print out for 322 bhp at 1.2 bar.
    I believe it is very well suited to a standard SR it has minimal lagg and still makes decent power.
    Why are you fitting a tubular manifold ?

    I know I don't have to fit a tubular manifold and could stick with a standard one, the turbo and manifold flanges I have I believe are warped so I would need a new manifold and was thinking it would be nice to upgrade whilst I'm doing stuff??
    Or would you say just stick to a standard cast one??

    They were and that's super cheap.

    Another option is to get a gt2871r and run the Oem manifold. More power and it won't crack

    When I was making my mind up about tubular vs. standard I was told to stay with the standard until 400hp. So at T28r power you should be fine.

    I fitted a tubular on my last s14 I had a greddy twin scroll turbo and didn't notice any difference in performance over the standard.
    I think you would be better off spending your money on a sr20de throttle body a bell mouth elbow and a straight through 3" if you haven't fitted those bits already.
    Personally cant see the point in spending an extra 500 pounds for another 20 bhp and shit loads of lagg.

    My Japspeed tubular manifold is faultless so far after 6 months! Goes a gorgeous burnt blue/purple colour
