I wanted a diesel too! I was wanting a VW diesel like what was in my 2006 Jetta. I am now thinking of one of the newer Chevy inline engines 4, 5, 6 cylinders. The 4.2 L I6 Atlas LL8 is what I was thinking of. Fortunately the current engine is running and I have time to think if that is what I want to do or not. Would be kind of cool to have one of the late model Chevy inlines.
