well.. off the top of my head.

s13 redtop and blacktop are the same. except the s13 blacktop has some heat sink looking fans on the front of the block.

s13 redtop and s14/s15 blacktop are different mainly because they have a vvtc timing system. they also have upgraded ball bearing turbos and slight bigger injectors. there are more, but i dont want to think. GO SEARCH.
