HI there, I've had a 93 Amigo 2.3 hangin out in my driveway for years now - it needs a lower end kit, just haven't gotten around to rebuilding. My query is this - is there an inexpensive diesel engine I can replace this with and then convert to biodiesel? It will just be a city-runner, and gas is starting to eat my lunch with my 94 4runner. I know there are also electric kits available, but my concern was with the smaller engine, plus the kit's not cheap. Any advice on the subject would be great too, thanks! JT
