Good write up - I worked as a mechanic years ago and have tinkered with big diesels and some with smaller ones. The turbo point is a good one though not all diesel engines are happy with them - Isuzu's turbo Trooper wasn't a happy marriage, for instance. Turbos like clean oil - you can't get away w/o an oil change like you can with as NA motor - not that THAT would be a good idea either. You'd need to calculate out how the vehicle will behave with an engine of vastly different ho and torque specs. Again, though I love old Troopers and have had several, you can't really drive the diesels on the hwy for very long.
My VW GOLF Tdi on the other hand hold 90 w/ no problem. I'm thinking about bumping up the tire size a notch - it really needs another gear. I've chipped it and VAG-COMed it and it flies - I have bigger injectors but it doesn't really need it. The clutch is not particularly strong and some people who have gone full-bore with hopping them up report the stock clutch slips. I think I'll wait until this one goes then replace it with a VR6 clutch. lres1 wrote: >Mike > >The Toyota Diesel engines into the US Toyota pickups, Hilux, 4Runner, Surf >and many more is an easy transplant from 4 cylinder petrol/gas to 4 cylinder >diesel as you say. > >For Toyota the Bellhousing needs to be changed along side the engine change >as the starter is on the opposite side in the diesel.
