I know they are both K-blocks, but how are the bore, stroke, heads, valves and all that stuff compair. Can I run RSX parts on a TSX or is it like the B20/B16-18 bore differences??? Specs like that are hard to come by.

ummm not really hard to come by...it is called "SEARCH"

I belive the K24 Bore is 1mm larger, and the stroke is 101mm vs. 86mm.

Thanks, are the heads the same? Thats more of a concern for me at this point. Are the blocks different heights? Trying to research the exchange of RSX performance parts to a TSX engine.

the k24 block is higher

the heads are similar but the k20a2 revs higher = flows better

higher revs does not = better flowing heads. some people say the TSX head is the same as the RSX type S head. some people even think you can take type S rocker arms and cams and install them into a k20a3 and have complete ivtec. some people say that the a3 head has smaller ports than a type S (k20a2 and jdm k20a) heads.

bottom line is that the 99mm stroke is made for some low end torque and not high revving top end hp. thats the way honda designed it. a 99mm stroke crank isnt all that practical in factory production car as a high revving motor, its just so heavy and works best spinning a little slower.
