Actually this can be successfully and legitimately worked around.
I fitted an LPG kit to my Land Rover, with no previous experience of it, just a lot of research. I reckon I saved £500 doing it myself! And that includes the inspection by a registered fitter who provided me with a certificate of safety, which my old insurance company accepted without question.
My current insurer, however, sent a form to be filled in about the modifications, who fitted them, and their qualifications. The LPG and numerous other items were all listed as fitted by myself, with a qualification in 'common sense'. They didn't ever question it.
I was thinking about a diesel Minor recently. I can vouch for the ford TD engines economy, my dad had a Mondeo and an Escort as company cars in the early 90's. The Mondeo was regularly over 60mpg, great... if it could be made to fit, and wasn't too heavy!
If you were fitting a sufficiently more torquey engine, would it not be unwise to retain the original gearbox as they can be made to go bang easily with the std engine. Would a type 9 and 3.7 diff not make more sense? And disc brakes.
