In terms of factory/stock specs the type r doesn't really differ that greatly from the k20a2's found in a type S. Now, my question. Would I be paying 5 grand for a rare item or potential serious power gains? I understand the k20a allegedly can handle a ton of hp without being built. $5k is a lot of money for an engine that would STILL need a turbo to get up there in power, which would cost me another 2-3k. Does anyone have any experience with tuning an all motor k20a? Am I in over my head here?
