I recently bought this Garrett turbo second-hand, I'd like to find out the model number so I can get an oil restrictor, wastegate actuator, and possibly a rebuild kit. The measurements I got from the compressor and turbine wheels are as follows:
Compressor: 47.3 mm small side, 60.1 mm on the larger side
Turbine: 41.3 mm small side, 52.6 mm large side.
The exhaust flange appears to be a T25. The compressor housing also looks strange to me, as there are no markings on it. Is it an aftermarket housing? Did someone shave off all the markings and polish it? Any info would be much appreciated!
