K20's have lots of top end..I had a k20a2 , but of course that was in a heavier RSX-S.
but, I've never driven or ridden in a b18c EG or EK hatch, much less a k20a swap, hybrid-racing seems to everything for the swap though. I just wouldn't wanna swap a b18c and then down the road wish I had saved more done a k20a, thats why I wanted to know how they compare from driver experience.
Havent really heard much from ppl who swapped a b18c-R into an EG though.
