I think this is a GT42 of some kind. It came off a Detroit 60 series semi I think. It is fine despite how it looks. It will be going on my truck this winter or spring once it has been gone through and customized.

 

A french horn?

 

Its a nautilus!

 

when you do the install take pics. I have one of those too if I want it off of a detroit series 60

 

it looks like a 42 i check around my shop i might have one layin round

 

ya i think its a older 60 series turbo.

 

If you know what the sizes are on this can you post them. It would be nice to compare it to anything else in the turbo world.
