what should the stamps say if the gsr motor is a obd2 and jdm? b18c ? and what should the head say?

 

the block will by stampped with "B18C"
the head should be a P72 with a date stamped with 96 or newer.
the distributor will only have one plug instead of two.
the injectors have the "easy" removeable injector plugs. the ones u squeeze on the sides and they pop off.

 

you have seen jdm obd2 motors before right?

 

yes..
