Found a turbo on Craig's list for 50.00 . Says its off a late 70s cab over with a cummins and it does not have too much play in the shaft. He had plans for it but is moving out of state now and wants it gone. I live 3 hours away from the turbo but my sister in law lives near him and could pick it up for me when she comes to visit next week here is the link

Large turbo for jet engine project

What do you guys think? Usable for a future compound setup?
Thanks

 

Count the blades and get the A/R off of the compressor and turbin housing and post them up.

 

10 blades intake looks to be double blades. 13 exhaust . Inside the inlet has numbers 19753nff exhaust outlet numbers inside -214652. I called him and these are the numbers he gave me. Also has numbers 3mnfo

The date on it was 7-19-73 or 7-19-78 he could not tell if it was 78 or 73 casting number

 

Ill talk to my turbo guy tomorrow and see if I can figure anything out for you.

 

Called a holset dealer in WA and he told me a few ways of being able to tell ie - bolt pattern and how many bolts for the flange for the exhaust. Really thick flange , rectangular port, 6 bolts indicates it probably a vt 50 or something similar. Not very desirable from what the dealer said. He said Borg and Warner have more efficient replacements for 5-600$ . Still it's only 50 bucks for a turbo in good shape or I could put that 50$ towards a 4k gsk and valve springs. What do you guys think?
