This turbo belongs to a friend of mine who bought it for his DSM project. The turbo has slight shaft play and probably needs to be rebuit. I do not know what kind of turbo this is as the shop building the motor disassembled the turbo to put the compressor housing in a glass bead blaster and blew the tag off. The original garrett tag seems to be in place however.
Here are the numbers that are on it.

I have no idea what this thing is. Just a semi-large turbo with some shaft play I guess.
