A Browntop ZC is exactly that... "browntop" meaning it has a brown valve cover. It comes from JDM 1983-1986 Civic and CRX 1.6i-16 models, their version of the Si. It is identical to EDM D16A8/9 engines, and similar to US 86-89 Integra D16A1 engines. It is very different form the Blacktop ZC that all the 88-91 guys use.

Browntop ZC swaps are very uncommon. You would probably have to call up an importer and special order one. The Browntop ZC is rated at 135hp. You could also use a D16A1 from an 86-87 Integra, however it is only rated at 112hp.

The swap needs, bare bones, a complete engine with harness, and one of the Integra control boxes. Swapping in an Integra ECU would be nice, but not required, and requires more parts to work right. Your transaxle will work fine with it. The Integra trasaxle can also be swapped in, but you need the axles and hubs from an Integra to do it.

BTW, on an interesting note, Honda has made engines with brown, gold, blue, red and traditional black valve covers. Neat, huh?
