Well I picked up a ZC last weekend. Stamped ZC and is stamped 92 above the exhaust header. I own a 91 ef hatch. This apparently is an obd1 motor... A few questions and concerns are. 1. Will the si cable tranny clutch/flywheel that I have work with this motor? 2. How can I convert this to an obd0 motor, or do I have to convert it to obd1? 3. Are the mounts the same as the rest of the ZC's? Can I easily mount this in my 4th gen? Thanks for the replies.
