Acadia Engine Swap

[mjoegl03]

HAs any body tried or thought of an engine swap. Like a diesel engine. Not a industrial but somthing between a 6 or 8 cyclinder diesel engine?
Its been done on sedans and small trucks so why not the acadia?
I hate the current engine being used in my awd

What is wrong with it? That V6 pushes it around nicely, could do a beter job on the MPG, but it's fine from what I have seen.
