ZC(similar to D16Y4, D16A8, D16Z6, D16A1, D16A3, D16A6, D16A9 and D16Z5 engines)
A few D-series variants are labelled (Japanese: Honda ZC engine) (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 D16A6 ('91 - '96) and D16Y4 ('96-2000) engine, but with more aggressive cam timing.

The DOHC ZC is similar to the D16A1, D16A3, D16A8, D16A9 and D16Z5 engines.

1st Gen ZC Identified by: External coil, small distributor, dual butterfly TB, cam cover bolts on top, brown/gold cam cover. Large cam pulleys. +3cc PG6B pistons, non-pent roof combustion chamber. As a ZC it appeared in JDM AV Integra Si and JDM E-AT Civic/CR-X Si. Commonly produced at the time but now over 20 years old and getting harder to find. D-series version D16A1 '86-'87

2nd Gen ZC (rarest) Identified by: Internal coil, large distributor, single butterfly TB mounted on slight angle forward, bolts on top of cam cover, black cam cover, large cam pulleys. +7cc PM7 pistons, 43 cc Pent roof combustion chamber. As a ZC appeared in JDM facelift AV bodied Integra Si did not appear in Civic or CR-X, rarest ZC only produced for less than one year. D-series version D16A1 '88-'89 (sometimes +7cc P29 pistons)

3rd Gen ZC Identified by: Internal coil, large distributor, single butterfly TB. Black cam cover. Cam cover bolts on the sides. Small cam pulleys.

4th Gen ZC Identified by: Internal coil. OBD1 EFi system (grey plug). No cam angle sensor on exhaust cam, now located in distributor. Rubber plug where cam angle sensor would mount. Black cam cover. No PGM-EFi plate on the inlet manifold, replaced with three ribs instead. P29 stamped on inlet manifold. MAP sensor on TB. +7cc PM7 pistons, pent roof combustion chamber.
