Other differences between 1st/2nd gen JDM motors include the color of the plugs, PGM-FI sticker not installed on the 2nd gen and some other stuff I can find again if you need it jan.
You're right about the upper (PGM-FI) sticker on the IM not being there on the 2nd gens... I have a few friends with different year JDM B16A's (1 CRX, 1 Coupe and 2 Hatches) so I'll see what the head codes are and there differences...
dawhiteboy: you can tell if the motor is a JDM vs. a USDM just by looking at the block code... JDM will say B16A and the USDM motors will say B16Ax (X being #2 or #3).
