ZC

A few D-series variants are labelled "ZC" (usually JDM), but they are not truly a different series. There are both SOHC and DOHC ZC engines. The SOHC ZC is similar to the D15Z4 and D16A6 engine, and the DOHC ZC is similar to the D16A1, D16A3, D16A8 and D16A9 engines.

Euro Mk1 (85-87) 1.6 CRX's are fitted with an engine designated "ZC1" which is a higher spec 120bhp version of the D16a1.
