I need help form you turbo gurus.A friend of mine literally gave me this turbo but I want to know what the full specs are and if its even worth me keeping for myself for some small boost in the future.He said it supposedly came off a 5.9 cummins.

All it says on it is Cat on the back. Then from what I can make out the numbers on it are as follows.

DUC 667590 - B 1.57-o.60 GB1

Does this make any sense to anyone.Appreciate any insight to what this really is and would it be worth me using for maybe 6-8psi on my motor one day.Thanks
