wow, so much misinformation in this thread.
Stock clutch for 240-250whp? wont last a week.
B16s have the same gearing as ITR trannys. CERTAIN year ITR trans had 4.7FDs. but those are hard to find.
Cam journals being off? uhhhh the cam journals cant be "set", and in a honda head, they really cant be machined either.
no the "assembly and machine work" part im talking about is PRECISION work. KNOW your bearing clearances, know your ring gaps, KNOW how to degree your camshafts in. If you dont know what any of that means, high whp NA motors arent for you. just go turbo. otherwise all your doing is halfassing a build.
Not many people on here know how to build an NA car an few have had success. Id take what you hear in here lightly. Truth is, very FEW have even made over 200whp, and only 3 people i know of have made over 230whp locally. check out my thread stickied in the the ALL MOTOR
