Are you trying to find this in Japan or just in general? Because I doubt many people on this board would be able to help you if you're getting it in Japan. I'd just check a junk yard, they're bound to have a bunch of them. Now if he doesn't care if he just gets the motor and stuff than I'd try
www.passwordjdm.com for everything but the A/C pump, powersteering pump, and the whole wiring harness.
