guys i ned some info on the r33 5spd boxes , story is i just went to look at one but , im under the impression it may be a n/a box as the complaince tags of the car were rb25de , but in saying that the car was turbo , so it might be highcomp or a turbo motor put it at some time? the g/box had a code RB2571C on the side of it , can any tell me if this is a turbo box , or are the n/a rb25 and turbo boxes the same Close Thread , Thanks Inflytmelb Legend Some original photos have not been recovered yet.
