the D16A1 is a bolt-in to the 1st gen CRX - you need to use the 86-89 Integra transmission, intermediate shaft, axles, knuckles/hubs and shift linkage - the easiest way to do it, as far as wiring, is to use the 86-87 engine with the vacuum advance ignition and the 1st gen CRX Si engine and chassis harness (1st gen CRX Si was also vacuum advance) - if your car is not the Si model, you are going to need to replace the entire fuel system and most of the wiring in the car with the fuel and electrical components from a 1st gen Si in order to run the fuel injected engine - to use the 88-89 D16A1 with the electronic ignition requires adding a lot of wiring even if you have the Si - here is some of what is involved:What the bloody hell? I coulda sworn I read in the FAQ that the D16A1 was a direct bolt on to the 84-86 CRX chassis. What the hell is going on? People keep giving me contradicting information, and its starting to piss me off.
the D16A1 from the 86-87 USDM Integra is basically the same as the DOHC ZC which came in the 84-87 JDM CRX/Civic Si models - that ZC utilized the vacuum advance ignition like the 84-87 USDM CRX/Civic Si - the ZC was 130hp due to higher compression and different cams - it is commonly called the "browntop" ZC due to having a brown valve cover, with 4 attaching bolts in the middle - does not bolt into 88-91 CRX/Civic - does bolt into 84-87 CRX/CivicI thought the mount points on the D16A1 were completely different than the JDM civic ZC motor.
Are you saying the 86-87 D16A1 is the same as the ZC, but the 88-89 is different?
