can anyone help ID this turbo

[malibu81406]

I recently bought a 1988 monte SS with a buick turbo drivetrain. always wanted a turbo buick and finaly got it in a chevy. The car has quite a few mods and was told by the owner it was all done at hartline perf. They gave me reciepts for most of it but nothing showing what turbo. The car has champion iron heads,studded top and bottom with billet mains and girdle, ported intake, 205/210 cam 36lbers , thdp converter etc.
Ok so the only numbers on the turbo I can find, garret m24 a/r .60 and has the integral bell 3" not the bolt on with 2 1/2 out. The only thing on the exhaust side is .82? havent pulled the thdp off to measure yet but intake side measures around 2.5 cant get in there with my mics.Sorry so long want to give all the info I can. I have done tons of searches with no luck so a BIG thanks to anyone who can help!

The integral inlet bell makes it a "TE" housing in TR-speak . Most popular small turbo would be the TE-44, followed by a TE-60, if the turbine housing has "garrett" cast into it. If the turbine has "precision" cast in, then the possiblities grow a lot. Pull off the compressor outlet hose leading to the intercooler and look all around for any numbers scratched in where the hose covers them up - that's about the only place turbo makers put a model. A true final answer will require measuring both small and big diameters of both wheels, but just using a bore gauge or something similar to measure the id of the compressor housing right where the blades start, and the id of the turbine cover hole right where the blades stop, to about 0.01" accuracy, will give you an answer. Subtract about 0.04" from the housing measurements for clearance to get the wheel diameters, and start with the table in the tech articles at www.gnttype.org.

I have doubts about the exhaust reading .82. That looks exactly like my TE-44.
