help identifyng precison TA series turbo (with pics)

[stephen p]

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.

Could be a TA60 or 62. Just pull the compressor cover off and measure across the comp wheel at the leading outside edge of the blade. A 60mm will read around 60mm. TA-49 will be 58mm, TA-62 will be 62mm.

Looks like a t04e60 compressor. Ta49 most likely

That would be incorrect. The "ta54" had a 60-1 with t04 69 ex wheel. You may have the 69 ex wheel but without checking you won't know for sure.
