Hi guys, I just acquired a slightly used turbo. The fellow I got it from doesn't seem to know much about it though, so I thought I'd ask the diesel gurus. He tells me it's a 64/71/14 S300. The number on the tag says.
Borg-Warner
P/N 175516
S300S
2A161080139

Hopefully that will help oh and inside of the exhaust manifold side says 091.
