Not too familiar with the D-series engine..... my CRX Si beater is beginning to smoke, and i suspect that it is the rings; it smokes slightly upon acceleration from a stop. I happen to have a D16 from my 96 Civic DX lying around. How straight forward is the swap to the CRX, since the engine is OBD2? Do the heads flow differently? If not, I plan to swap over the entire engine. If so, I plan to just swap over the block.

Thanks
