Decoding OEM Nissan turbos

I just got back from my buddys place and while I was there I noticed he has two nissan turbos sitting in his garage. Is there a way to decode what they are and what they are from by looking up some numbers stamped on the housings ??

it should say the make and the size like t-25 for example that should help not sure how to check the car make though

look for the stamps on it. Should say size of A/R. Post pics.
