Does it have all the stock stuff from your last engine on it? How did they know. They actually look at the zc on the block or you tell them?

Its my understanding the block code must have a USDM equivelent, IE B16A=B16A3, but where theres no ZC in the US its not considered a legal replacement engine, even though if you swap the intake and exhaust manifolds its pretty much a Y7.

don't live in CA? =P just kidding it was my understanding that CA dosent let you swap anything that's not original regardless of the true emission value of the engine. and dont they run engine codes there due to crime rate of auto theft?

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 SOHC VTEC ZC is similar to the D16Z6 ('91 - '96).
The DOHC ZC is similar to the D16A1, D16A3, D16A8, D16A9 and D16Z5 engines.
DOHC ZC
Found in 1986-1991 (JDM) Civic and CR-X
Specs:
Displacement : 1590 cm³
Bore and Stroke : 75 mm X 90 mm
1986-1987 Compression : 9.3:1 1988-1989 Compression : 9.5: 1
1986-1987 Power : 113 hp (84.3 kW, 115 ps) @ 6250 rpm; Torque : 99 ft·lbf (13.7 kg/m, 134 Nm) @ 5500rpm (US)
1988-1989 Power : 118 hp (88.0 kW, 120 ps) @ 6500 rpm; Torque : 103 ft·lbf (14.0 kg/m, 137 Nm) @ 5500rpm (US)
1988-1991 Power : 130 hp (96.9 kW, 132 ps) @ 6800 rpm; Torque : 106 ft·lbf (14.7 kg/m, 144 Nm) @ 5700 (JDM)
Valvetrain : DOHC
Piston Code 1986-'87 : PG6
Piston Code 1988-'89 : PM7
Fuel Control : OBD-0 MPFI
Euro Mk1 ('85-'87) 1.6 CRX's are fitted with an engine designated "ZC1" which is a higher spec 130 hp (96.9 kW, 132 ps) version of the D16A1. Which were later to be switched out with the D16A8 or B16A depending on which model.
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. Inlet Manifold stamped PM7. +7cc PM7 pistons, 43 cc Pent roof combustion chamber. As a ZC appeared in JDM EF3 civic and EF7 CR-X, did not appear in an Integra body. Most commonly produced ZC, manufactured in Japan from end of '87 through to early '91 D-series version D16A8/9 (Euro Civic Si) (sometimes +7cc P29 pistons)
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. As a ZC only appeared in EG5 Civic bodies, no Integra or CRX received this engine. Reasonably common produced from '92 to '94. (20th Anniversary edition & Japanese car of the year) D-series version D16A8/9 (Euro & Australia Civic Si) (sometimes +7cc P29 pistons)
The non-VTEC SOHC ZC is similar to the D16A6 ('91 - '96) and D16Y4 ('96-2000) engine, but with more aggressive cam timing.

Your motor is too old to be in your car. Automatic fail. The motor you put in your car has to be your year car or newer.

You might as well just switch heads on your old motor because it will be cheaper and a less of a hassle. In order to legally get it smogged is to get it bar'd and from what I hear, you can no longer bar JDM motors. Do a quick search in h-t and you will find tons of threads about baring a JDM motor. I also live in stockton and gave up my crx with a zc swap with tons of mods because of this hassle.
