just for technacality's sake, this should be in Z32/tech

but to answer your question, I don't know what all the rage about JDM engines is lately. The JDM engines come with the automatic trans. cam profiles. That and they get smaller turbos than the U.S. spec motors. The JDM motors are rated at 280 but are usually measured at a little beyond that.
It's up to you on how you wanna spend your money. Having the lighter/stronger pistons, rods and rings done to your current motor will probably run you the same as swapping engines will. Unless you do the work yourself, of course. Then the difference will be the end cost of the parts. Replacing the bottom end is like essentially putting in a new motor.

He mentioned JWT Sport 500's. The 500 being plural, I'm guessing he has a Z32.
