complete engine overhaul questions.

chii370

assuming i still own my Z in the near future thanks to the economy, and i get into the army as planned :P i have a few questions.

first, im looking at not just blindly putting a turbo or a SC on the car like a tard to get instant gratification power. that being said, im talking cam, heads, pistons, crank, rods, lifters, everything. and a bore. probably to 4.5 if the stock block will take it. but theres an issue.

MOST if not all of the parts i manage to locate for example on GTM site are mostly for the 350z engine. Now, do any of you know of where i can get all these parts LIKE the stage 3-5 engine components for the 350 offered by GTM, but for the 370 specifically. Is anyone even making them yet?

My goal is to make this engine produce roughly 500 WHP without using any forced induction. which shouldnt be to hard IF the parts even exist. I just dont know where to look. and i refuse to buy a built 4.5L stoker for 20k, not because of price.... but because then i would have MY oem engine left to deal with, which IMO is more then capable of producing IDENTICAL results.

Secondly, what kind of clutch system works best in the 370, and what would work best for my needs? i looked on GTM and theres like 20 different kinds..... single, double, tripple, quad, w,w/o damper, and a million other options that i dont fully understand. im not making a 1k WHP car, 500 to the wheels in the goal.... so an explanation of the different clutch systems and what they even do would be cool too :P

I was always an American muscle kinda guy prior to my nismo, and its EASY to get an old 401 or 350 or whatever manufacture you are into, and just buy the parts, install them, and make massive power with minimal fuss. same goes for transmissions and rear ends. i dont see why this should be any different. with 9500$ you could make a amc 360 motor pump out 850WHP.

Any help/info would be appreciated. thanks guys.
