I have seen a couple of variations in R32 RB20 turbochargers , I think there's an early and a late . The one I used has 16V 11 cast into the compressor cover and for some strange reason has a compressor wheel that looks like the early RB25 type compressor , it has the anti reversion groove in the cover as well . I'm sure its R32 because it does not have the larger ARR cover that the RB25's have nor the bold block lettering cast into it . The three bolt out let was from an RB25 turbo and had the bolt hole centers moved to make it fit . It has the cast in tapped boss for the wastegate actuator which R33 25's don't have . I have seen other versions that use a different compressor (smaller with wider spacings between the full hight and spliter blades) .

Probably a long shot but in one of the earliest editions of High Performace Imports magazine there was an article on the different versions of the RB20DET . It went into some detail on the various std RB20/25/VG30 turbos with several pictures .

Hope this helps , cheers A .

My R32 turbo only has 16V on the comp cover. No numbers after it.

Its a late 1992 R32.
