Rb25 Turbo Question

[SMiTHBRo]

this may have been covered elsewhere, i did a search and couldn't find what i want to know about RB25 turbos. please link me to any relevant threads if they exist

in my posesssion i have 2 different rb25 turbos. one marked 45V2, the other 45V3. the 45V2 is currently running on my rb20 but the bearings are screwed. what i'm considering doing is creating a 'frankenstein' turbo if you will....mating the exhaust housing from the 45V2 to the rest of the 45V3. this is because the 45V3's exhaust flange has a bolt snapped off in it. is this possible? what is the difference between these turbos? i'm under the impression that the V2 is a series 1 turbo and the V3 is a series 2?

It is possible. the 45 v1,2,3,4 are just different revisions of the compressor cover, but they're actually all the same. I've had all 4 next to each other, and there is no difference.

As for the exhaust housing, just undo the bolts, put the turbo in a vice and knock the housing off, then put it on the other. bob's your uncle.

Not meaning to hi-jack. . . . .but I will

Has anyone ever managed to find a compressor map of some discription for the RB25 turbo?

Best person to ask would be disco, but i rarely doubt there is an exact map for the rb25 turbo as it was a nissan type turbo, although garrett supplied them didnt they? Not sure
