Alright here it is, my father and I are rebuilding the motor out of my race car. The motor is an 87 Integra Motor, code D16A1, with the jspec equivalent being the ZC motor. A few upgrades are in order in the process. We bought a set of Pistons off of e-bay, supposedly fropm the ZC motor. After comparing them with the ones we already have from the 88 D16A3 motor, which is different from the 87, we found they are exactly the same. Both stamped with the code P7M. So we are sending them back, assuming that the seller is just generalizing like people do and calling all the DOHC non-vtec integra motors of that generation ZC motors when they are not. Thus my double question is, what is the difference between the ZC pistons and the ones from an 88 D16A3 motor?? Is there a compression difference. We are already planning to put the 88 D16A3 pistons in the 87 D16A1 block which should raise compression, will the ZC pistons make that any difference?? Also does anyone know where I could buy a PM7 ecu. This is the ecu from the ZC motor and there is an excellent performance chip available for it, on top of the advantages to the current PG7 computer that runs the aspec one. Thanks a lot for all your help.

and no one has any clue

not too many people would spend the time and money taking an old motor like that apart and build it....thus i doubt the average hon/acu person would know
