so i have a 91 civic sedan..
i bought the car and it came wit a zc motor dual point.. wtf??
but the head is a vtec head. but its sealed off where the vtec solenoid goes.
does anyone know if this car comes with this motor or wats up? and if i can convert it to obd1 wat do i need????
please help guys.

 

What does the motor stamp say? a true JDM ZC will say ZC on it. If you want to switch to OBD1 get a rywire OBD0 to OBD1 wiring adapter, you put your ecu plugs in it making it possible to run an OBD1 ecu, AND you need to change the dpfi to mpfi...find OBD1 intake manifold...I would recommend the D16Z6 manifold, but any d series obd1 will work. From there it is all plug and play. Hope it helps
