Turbo identity question

[RocCitySlayer]

Has anybody heard of Garret Airsearch m11 turbos? I seen a few for sale the guy says 2 of them are M11 and one is T04. No shaft play all 3 for $50. worth anything or junk?

I wonder if any part of it can be used to improve my setup

They're all T04B Garretts....designed for low boost and slow spool on a stationary-RPM vehicle like a farm tractor. BAD choice for a performance turbo as you'll want the exact opposite for your car.

All of these turbos will have compressor inducers in the 50-55mm range and exducers of around 70mm....so at best they're a slow-spooling 20G that is more-prone to full-throttle surge.

Are the hotsides any good? Or just stay away all together?
