ID'ing a turbo
 

I found this turbo that appears to be a GT2560 journal bearing.
The CHRA plate reads:
Garrett
448179-5066
MJM00757

I can't find $hit on the Garrett website, or on google, or anywhere.
How do I ID this turbo?

I thought there was no gt2560 journal bearing.

there may be a turbo the same size from an old product line from garrett

(above is only what i think ive heard can someone confirm or dispute?)

a GT28 would be a "GT2560" journal.

Yeah, so based off the serial numbers, how do I figure out what it is?

call garrett.
