Hi swb, 92 td42 have the best pistons for fitting turbos, i have a 92 td42 and fitted a supercharger from a commodore, my opinion is far superior than a turbo more torgue in lower revs ie 800 plus, fully servicable and no extra heat, i get 8 plbs of boost at idle and then al thropugh the rev range, works out about the same dollars as fitting a turbo with a intercooler. Cant help with the diff ratios but have heard they are dfferent to the petrol. Best deal is look for a wrecked 4.2 diesal and buy the lot keep the good bits and sell the rest. Col

All TD42s have same mounts. Bellhousings are different on Petrol to Diesel.

I can put you onto someone that has done a few of these conversions. Pete Christie of Christie Engineering(generators, and also Christie Creation the comp Truck)..

Mail me off list, there are few differences in the bellhousings and other bits and pieces...

but then again Pete will have those bits layin round too..
