In a few months I will be swapping motors. I was considering a GS-R motor for obvious reasons. ( its displacement, redline, pretty good power all around, even USDM version is respectable, even though I would get the JDM one). Then I read a Turbo LS is cheaper and has more power potential for the money. Turbo GS-R seems to expensive for me, I want to upgrade suspesion and get rims, ETC. (Even though VTEC is temping :0) OK so anyway, What internals need upgrading when u get a large turbo ( I will be getting some kind of ball-bearing turbo kit, because they are better.) I am hoping its just cams, valve springs, and retainers. If I need Pistons, Rods or a crankshaft, that would suck, because that sort of engine work is expensive.. right? ALSO... Sorry to bore you .. heh... I am also guessing a small turbo would be just fine.... small kits are still like $3,000 right.. cause right now im a little in debt so I have time to decide what sort of things I want to buy. I am giving a special thanks to whoever reads this and tries to answer whatever they can. oh yea... if I go the supercharger route, I again, am guessing the GS-R motor would be better. Thanks again, peace!
