Okay, question. Let's say I'm building an NA k24 motor out of a TSX. I've heard different things about what parts i can swap out w/ a k20 that will help hp numbers. If I'm trying to stay OEM as far as pistons, rods, crank, valvetrain and such, what would the ideal combination of parts between a K20 and a K24 be (including which head)? Also, I've heard (didn't know if it was actually true) that you can use an f-series crank in the K motors. Either way, what's the best all-honda combination to make power in a k24? Thanks
