It seems like every website i go to has a different parts list for the ZC swap. I have a 1990 si with D16a6 and i plan to put in a ZC engine soon. What are the bear necessities, parts wise, that I need to have this car running well with the ZC engine? Obviously the ZC motor is needed, but I plan to keep my stock transmission and possibly my ECU. If not, I'll get the Integra ECU eventually, otherwise, what else is needed? thanks a lot for the help.
