Can anyone help me out, im now trying to sell my turbo and im not sure what it came off, the person that sold it to me said they think it was off a skyline, but they werent too sure, they had a few turbos around.

Its a nissan motor BB turbo, oil & water cooled, with a 0.63AR rear housing, only thing printed on the front is Nissan motor & 13






any help would be appreciated
