Blue Top Big Port 88kw - Came in AE82, AE86, AA63* First model, 16V small crank (3 rib block), cheap and nasty, good bang for buck. Great for RWD swap
Red Top TVIS Big Port 88kw - Came In early AE92's* Came after the Blue top, same head, altho has slightly less duration cams compared to blue top. And also has the bigger crank the same as all of the following models. (recognised by the 7 rib block)
Red Top Smallport 100kw - Later Lodel AE92's* made from 89 onwards, has smaller ports than the earlier 2 which resulted in more power and no more TVIS. 100kw from standard, strong as, potential for big power, down side is they are quite sought after and dear. (many believe they are a better package than the silvertop)
Silvertop 65kw - AE101* First of the 20V engines, pretty good altho most of them are flogged out, mistreated and make next to no power. Have a bad reputation. If ya get a good one theyre fine. Hard to use for RWD swap due to the dizzy sticking out the back of the head.
Blacktop 112kw - AE111* Last of the normal 4AGEs, same as silvertop, but with much better head, and cam design. Altho the rods are small and even stock dont like to sit at 8000rpm for long, many have stuck thier head outside the block for a look.
VTEC TOP 1,000,000KW - If you dont know, dont ask, you arent worthy of knowing. Even if you did get hold of one and got it installed youd probaly hit 4500rpm and your brain would turn inside out and youd spontaneously combust anyway.
