What is the difference between the U.S. and Japan made models?

All NX's were made in Japan. I don;t know what you are asking, but there was the AD22VF brakes that were found on some NX2k's...

its the way the list them on ALL parts books. cause they assume all b13's were made in both places. hell ive had the dealer swear up and down to me that the NX was made here in TN cause "the computer says so". But if you are buying them or stuff for them always ask for 1991 Nissan NX2000 with ABS made in Japan. That should get you the right thing 90% of the time

Yes, when I ordered mine from the dealership I worked at, I remember that there were ABS and Non-ABS parts... you want the larger ABS setup.

Cause I called Summit for the Brembo OE rotors and the guy listed U.S. and Japan made rotors. The Japan ones were a bunch more. But the rotors for the U.S. were ABS.
