im lost and dont know what parts to buy for this engine... i was told a 94 integra GSR would fit them but just checking im about to get a diagnostic on it here soon, it was running really rich, and throwing fuel supply code.

 

OBD1 ZCs use a parts from a bunch of different vehicles depending on what it is you need, most internal parts are for an '86 - '89 Integra, things like O2 sensor, distributor cap and rotor for a '92 - '95 Civic Si. other parts like the distributor aren't available in north america.
