Have this old turbo laying around. Pulled off truck for a bigger unit. Has been sitting on a table for months. Didn't smoke when I had it on the truck. Doesn't have much play. Best I can tell its fine. I do not know the mileage. If someone wants it I'll bring it to the ls1truck day. 250 I think is fair. If not I'll leave it at home and keep being a pack rat.
