i just bought a 90 crx si with a zc motor in it and i was wondering what size the dizzy was. It can't start bcuz it needs a new si wiring harness. and the owner of the crx that I bought it from took off the dizzy. I don't know why. i was just wondering how big it is. I tried putting the dizzy on but the bolt patterns won't match up to the head. the dizzy kinda look big.

 

is this a DOHC ZC? if so, you need distributor from 88-89 Integra

 

yes it is a dohc
