Hey guys I need some help identifying a turbo. I bought a turbo off of a buddy of mine and he claims it came off of a bulldozer that was powered by a detroit(don't know what model engine). It says airesearch a.p.m m.10 on the compressor housing and has a .83 stamped on the inside of the compressor outlet, it has a 4" inlet on the compressor, looks like a t4 flange on the exhaust with a 4" vband where the downpipe hooks up. It's too rusty to see anything on the exhaust housing..... Please help!
