I'm trying to figure out what turbo is fitted to my mates 2wd....
Cast on the compressor housing is "Garrett A/R .50" and there is no take off to provide a boost source for the amal valve and then on the turbine housing is "Garrett A/R .48"

There is a small metal plate attached to the rear of the compressor housing that says "Garrett" and "Allied Signal" with the s/n CK00183AT04E46
