I need to buy a compressor wheel for this turbo and can't figure out what it is. I believe it's some sort of industrial turbo, it's a Garrett and was sold by AlliedSignal (a company that no longer exists). It has a 4" inlet and 4" outlet. I used a mic and the compressor wheel inducer is 60mm

Here is the info I have and some pics. Any help would be greatly appreciated.

Information on compressor housing:
Garrett
AR.56
M43
AlliedSignal
P/N 1825457C91
S/N BDL30502

Center:

Turbine housing:

G3
A/R 1.11

The compressor wheel has a part number, 8856-9. I couldn't find it on any turbocharger part websites.

 

Found out. Just in case anyone else has this same turbo and wants to know what it is, its a gt3782.
