oh, i was pretty sure that the a1 were jdm. i know they sure as hell aint USDM becasue we never had that engine here, maybe the a1 is edm. but from those pics it looks like both motors are a gen 2 motor, ones just mated to a cable tranny. its hard to tell because the pictures that show you the engine stamp, dont show you what car its in. i know the b16a1 came out of the CRX sir, and i was sure it was from japan, making it JDM. i could be wrong, but im unsure until i hear more opinions on this.
