i just picked up a buick yesterday, and it seems to have a great deal done to it, i was told it had a "precison 52mm turbo" nothing really specific other than that. looks stock, but i know the t/a series turbos do look stock. the exahust housing says precision, here's a picture of the wheel, with the bell off, and the gasket off, the inside of the inlet measures about 30 thousands over 60mm. any idea what turbo this is? i did not see any other identifying markings.
