I got wepon r secret weapon air intake, obx stage 1 intake manifold, jdm header with 2" inlet and 2.5" outlet, high flow cat 2.5" piping, 2.5" full catback exhaust. That is pretty much it. I gonna get stage 3 clutch with 8lb flywheel which is gonna help when I wann double clutch or just better lauch off the line.lol. And there was the cam gear. The thing is losing weight off the flywheel or cam or camshaft helps the engine because of the less weight it has to turn so it free more of the engine horsepower. But that is what I think and also that was what the autotech teacher said.lol
