is it a true JDM DOHC ZC or is it a D16A1? - D16A1 won't bolt into your car - there are no DOHC D16 engines that are VTEC - DOHC ZC distributor is the same as the 88-89 Integra D16A1 - Cylinder Sensor on the end of the exhaust camshaft is same as 88-89 Integra D16A1 - timing belt is the same as 88 Prelude 2.0 Si - water pump and timing belt tensioner are the same as 88-91 CRX/Civic Si D16A6 - gaskets/seals are the same as 88-89 Integra D16A1 - your old D15B2 starter and alternator will work - all of the mounts are the same as the D15B2 - the D15B2 flywheel, clutch and transmission will work on the ZC
