    Hi Guys,

    Will a GT2871r bolt straight on to standard manifold or will improvement/New manifold be needed?
    And what else will be needed if so?

    Hi Alphadrex,

    If you could let me know, also did you have to have a spacer made up?

    Hey Ally,

    So here's the list I came up with...

    GT2871R Fitting Tips:

    -Manifold Spacer...I didn't feel like going through the trouble of making it, so I just bought an SR20 Vibrant flange. It comes rough (i.e. warped a little), so I brought mine to a machine shop to be resurfaced. If I remember correctly I think I got the 1/2" one.
    -Extended Length Studs...you won't find them, make them from ready-rod (M10x1.25 Thread). Measure the stock ones add the thickness of the spacer plate and cut to length. I believe mine ended up being approx. 60mm but double check.

    -Clocking...get patient

    -Actuator...I bought a bent rod one from ATP Turbo because my clocking required a signifcant side strain on the straight rod one, and I didn't want to rely on a 25yr old actuator. If you want to use a stock/straight rod you can worm out the stock bracket on the clocking mounting holes to give enough, but it's still shady.

    -Oil drain...worm out fitting holes and test fit many times until adequate alignment is achieved

    -Compressor Inlet/Outlet sizes on the GTX were different than listed in the article, so you may need to buy different sized silicone hose adaptors/piping for your boost pipes.

    -Hoses/Fittings...got an SR20DET turbo fitment kit, but had to order a few pieces from a hyd. shop and ATP Turbo.

    I think that's all. Hope it works for you. If you go GT3071R, I think fitment gets even trickier...
