If you can get one, use the 2.8 turbo diesel instead of the 3.1.
The 2.8 gives better fuel consumption (in the same vehicle) , is more easily modified for more power, and is more reliable.
Lots of people here taking the failed 3.1's out of their MU's and installing the older 2.8's.
3.1's are known for cylinder head and turbocharger failures.
Other than that, good luck with the swap.
I would love to see it done.
