no you dont need the std comp for anything with the sm4, im pretty sure it can control everything you throw at it. If you havent already, go trade it in for the new plug n play version. Will save you a heap of hassle.
200 what sort of racing you going to be doing with your car to justify an aftermarket sump?
Nice build gemini90. Why did you keep the pcv valve there to the manifold? You should ditch it mate.
Nice plenum on there too, i wasnt aware hypertune made them for rb25's? If so, must have cost you a fair bit.
