I need a new turbo for my 01 ta ls1 with the sts rear mount turbo set up. Sts was bought out by holley and google searches havent helped. Was hoping someone here might have more insight on where to find a replacement. Theres not a brand name on the turbo only ar .60 on the intake side and ar .96 on the exhaust side. Any help on identifying the turbo or leading me in the direction of a replacement would greatly appreciated. Thank you

Replacing it with the same turbo is likely more work than it is worth. Just match the hot side flange, looks like a t4 , to a new turbo and then alter the rest if necessary. You should be able to find one close to the same measurements if not the same.
Might want to look for a used Turbonetics TC7568 Benita or whatever other name they have.
The TC Series have a T4 flange, .90 AR and with the smaller 68mm turbine wheel would spool pretty fast even being located at the back of the car.
Even a 75mm turbine variant may fine depending on your combo, something from VS Racing or Huron Speed since both seem to have excellent customer support.
