Am seriously considering swapping a diesel (preferably turbodiesel) into my '62. The 3FE runs well, but the fuel mileage plus the torque benefits of the swap are convincing. i'd want to swap in a 5-speed at the same time. Question is what is the best combo to go with? I seem to remember someone posting that has a 3B with AXT turbo. Wondering what is suggested considering cost/availablity in the states. Thanks.
