hey all u honda civic guys.........wht year make and model did the dual cam zc motor come in with the 88-91 civics need to know as i have one in my race car and im wanting to prove the tech inspector guy wrong if i get caught with it.!

 

I "stole" this from a site when I googled DOHC ZC


What is a ZC?

1st gen DOHC ZC - brown valve cover - came in 86-87 JDM Integra - will bolt directly into 1st gen CRX Si and 3rd gen Civic Si - will not bolt directly into 2nd gen CRX or 4th gen Civic.
2nd gen DOHC ZC - black valve cover - came in 88-89 JDM Integra - will bolt directly into 1st gen CRX and 3rd gen Civic, same as brown valve cover, however, it uses electronic advance distributor like 88-89 USDM Integra D16A1 - 1st gen CRX Si and 3rd gen Civic Si have vacuum advance distributor, so, to use it on 1g CRX or 3g Civic, you will have to do a lot of wiring changes.
3rd gen DOHC ZC - black valve cover - came in 88-91 JDM CRX Si and Civic Si - bolts directly into 2nd gen CRX and 4th gen Civic.
4th gen DOHC ZC - black valve cover - came in several different models of JDM cars 92 & up - is OBD1 - has Cylinder Position Sensor inside the distributor and will bolt directly into 92-00 Civics
SOHC ZC - basically the same as D16A6 (little more horsepower) - will bolt directly into 2nd gen CRX and 4th gen Civic.
SOHC VTEC ZC - basically the same as D16Z6 - OBD1 - will bolt directly into 92-00 Civic
