not the case. if you look on the top of obd0 b16 engines the pistons have pr3 stamped into them.

PM6 pistons are in the SOHC ZC and D16A6.

the USDM 88-89 integra has PM7 pistons, but i am not sure about the JDM ZC.. it would make sense that they also have PM7 seeing as how that is the ZC's respective code, but then the question arrises... where do P29 pistons come from?
