OK all you Diesel Heads. I need some specifics as to the difference between a '80 300D non-turbo head and a '83 300D Turbo head.

I know the turbo lower end of the engine is different from the non-turbo. My concern is the top-end.. the head, intake/exhaust valves, valve guides, combustion chamber size, injectors, manifolds, etc..

I need this info for a project that I may do.
I have a very good non-turbo head that I'm thinking of putting on a turbo engine with a BAD head.

Thank you all in advance..
Jay

I believe they are not interchangeable. I know for a fact the pre-chambers are different, The valves are different also. I don't know if the base head is the same or not.

What is the matter with the turbo cyl head???

Don't know yet. Just going by what the seller is telling me.
I'm going to look at it this weekend.
Pre-chambers can be removed if you have the tool.
My concern is the BASE head. Since they are both flat after the prechambers are removed.
