I have a buddy who is looking to do a ZC swap on his 88 Integra and I have run into some interesting issues trying to find any information about the job. Most of the sources that I've looked at say that a ZC won't fit into the 1st gen Integras but they don't go into any detail. I thought that the ZC was a JDM version of the D16 right? If so wouldn't the ZC share the same block as the American D16? I know that a B16 would be a better idea but he just doesn't have the money. Also if the ZC won't work, what's the difference between the ZC and the D16 that gives it the extra 12hp? Thanks in advance.
