I have thought about a diesel conversion in an old Ford before and there is a very obvious and worthwhile engine to use. The newish Transits have a 2.5 turbo diesel engine, with a 6 speed rwd gearbox bolted on the back already, which is not slow in anyway whatsoever (if it spins up the rear wheels in a loaded Tranny, think what it would be like in a Sierra!)
Highly efficient, modern so good parts availability, Ford rwd fitment already and bound to be a couple of written off Trannies about in the breakers. Or some guy (Birmingham area I think) who breaks only Transits and has rows of drivelines just sat there. All you need is engine, box, ecu and off you go!
It ticks all the boxes for the reasons to do such a conversion.
Any thoughts?
