I have read this article on the 2001+ jdm k20a engine. I was wondering since it 2.0L, same as the B20, than can't you just frankenstien it. I know custom engine parts are probably needed but, it seems like a cool idea. Oh yeah, I'm thinking of putting it in a 1990 Honda CRX HF just so you know. :sunglasse

I'm sure you could build a frankenstein with the bottom from another k-series engine, but I would think that it would be impossible to mate the head with a b-series, or any other series for that matter, block. Parts are only compatible within the same family.
