ZC(similar to D15Z4, D16Z6, D16A1, D16A3, D16A6, D16A8, D16A9 and D16Z5 engines)
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 non-VTEC SOHC ZC is similar to the D15Z4 and D16A6 engine, but with more aggressive cam timing.
The VTEC SOHC ZC is identical to the D16Z6, and the DOHC ZC is similar to the D16A1, D16A3, D16A8, D16A9 and D16Z5 engines.
