The ZC was a group of Honda engines for the Japanese market. There were several kinds of ZC. There is the brown top ZC(similar to D16A1), which only bolts into the 84-87 Civic/CRX, and not into the 88-91 Civic/CRX, so we won't worry about that. But just giving fair warning if anyone wants to give you a really good deal on a brown top ZC swap for your 88-91 ;). Then there are the black top ZCs. These include the DOHC ZC, the SOHC ZC (similar to a D16A6), and the SOHC VTEC ZC (similar to a D16Z6).
