I couldn't afford a 4BT at the time. A friend offered me a low mileage Mercedes 5 Cylinder Turbo Diesel, with transmission, accessories, wiring, etc for less than the cost of a junkyard 318. Engine ran fine, but the vehicle fell apart around it. So I dropped the Merc 5 Banger in, sold my A518 Torqueflite for what I had originally paid for the whole truck (Running and driving), sold some more parts that I no longer needed and in the end I ended up with a Turbo Diesel Dakota that paid me $200 after accounting for everything.
It reuses the factory V8 Tachometer (I modified the crank pulley to act as a reluctor and made a bracket to hold the original Dakota pickup in place), reuses the factory Dakota Radiator, Modified the motor mount brackets to use Cummins Motor Mounts.
For now it's a stock Merc 5 Banger Turbo Diesel. In the near future, I'm going to add a Supercharger to it (Compound Super-Turbo) and modify/crank up the injector pump.
