Been looking for a diesel truck and saw this, interesting.

i believe this is a VE pump engine converted to a p-pump. only reason i feel this is it is NON intercooled. has the "VE" style intake manifold

saw, that whats the deal?
Kinda wondered why the pipe from the turbo went straight to the intake. I don't know alot bout these, just what I've read on dieselbombers etc.
