1978 LeSabre 3.8 Turbo Sport Coupe

[bigjohnson]

The car that I have needs some clean up. I am having the carb rebuilt.
What I want to know is what type of turbo that I have? I figure that along with other things this can be freshened up. What will be a direct replacement turbo?
The unit has the following markings:
A/R .82 AOD

The stock turbo for the 78 Buicks was a TB0301. It had a 60 Trim
T3 compressor wheel and a 52 Trim T3 turbine wheel (4.2 degree
clip). If you are interested, that was the first wastegated T3
automotive turbo Garrett made.

Thank you! This will help a lot.
I have not found anyone that deals in parts for these cars. Anyone know of any?
