Mutt engine swap is not worth if you are going for a non turbo engine, reason if you are removing original engine with a diesel one you should get max out from the money spending on modification.
With a minimum body damage & to the lovely shape of Mutt, i advise you to put a 2CT with two major modifications.
1) You need to cut the body from left side facing Mutt to generate enoughf space for turbo,
2) Alter the chamber if you need a finished one 5000 is the cost made from a Professional chamber maker or you can do it in 1000 rs from any denter.
Bonet need to be raised less then a inch, ill take camera along with me today to give you the exact look
