My buddy has a jdm spec zc in his 89 honda civic. I thought all of the motors that came out of 88-89 Acura Integras were the ZC engines. I did more research and found that his motor came from overseas. And the ones in the American cars are called D16a1 and have a black valve cover. Same looking motor just less horse power. Also why wouldnt a d16a1 fit in my 88 crx. My buddys car had a d15b2 in his car originally and it had dpfi. Exactly like mine does now. And when he did his swap no motor mounts were changed other than the tranny mount. He used his stock 5 speed tranny the motor mounted right up. He just needed a wiring harness and a pcm from the integra.
