Diff's between A1 and ZC

[Christ]

I wanna compile a list of the differences between the USDM D16A1 and the JDM D16ZC (Twin cam D series) engines. Any information showing the differences should be posted here.

1. Obviously, A1 is USDM, and ZC is JDM.

2. A1 is Integra, and has several Generations, Including Brown Top, and Black Top, being 1st and 2nd gen, respectively, while ZC was 2 generations of Civic/CRX ZC, 88-91, and 92-95.

Any other info? I know that there is alot more info... but I wanna get this list going, since there is alot of misinformation out there about these engines.
