[QUOTE=a64nova;8543936]i made 400whp and 346tq with a stock bottem end, megan mainfoild, gt2871r turbo on 18psi, 550cc inj, hks 264 cams, and spitfire coil packs, on a martin rom tune, you dont believe it call him all thats has changed now and is not losing power its only going up........[QUOTE=a64nova;8543936]


fyi there is not much more power that could have been made with your old setup. stock rods are good to 500whp, evreything else internally is not made to hold 500, i.e. pistons, head studs, mainsutds, head gaskets, etc.
