Are Gtr Aircon Pumps Interchangable Between R33,r34 Etc?

[AAHH33]

hey, my aircon pump has kacked it, and need a new one for my r34 GTR. i called up nissan, and as expected they want $1500 for one.

so my question is, as i havn't had any luck so far finding a second hand r34 gtr compressor, can i buy a one off a 33 gtr for example? are they universal across the RB26 gtr's?

Bump anyone know? I need one for an r33 gtr
