good reading.. http://en.wikipedia.org/wiki/Nissan_KA_engine

They are all relatively the same... however the compression ratio on them are slightly different.

Check out the NA motor thread for much useful info. Big Vinnie the NA guru pokes his head in from time to time.

the blocks are identical as far as i have seen.. the difference is the head, cams, intake mani, and valve cover... head had different bolt pattern for the valve cover, cams on the s13 are more aggressive than the s14, s13 intake mani has the butterfly valves s14 doesn't... but the block is the same... hope this helps

biggest difference is the emissions from Obd1 to Obd2 you see most of the changes in the head and intake manifold.
