I think I am in love. If I had to pick one diesel swap to ever go through with, this would be it right here. Sporting a Cummins Diesel 4bt motor out of an old bulldozer, this Ford Ranger gets the transplant it has always deserved. Although this 4bt is completely stock (besides what I assume is straight exhaust) it has much more power compared to its 4 or 6 cylinder counterpart. Sitting pretty with a 3″ lift and 33″ Super Swampers, it has a much more aggressive stance over the stock puny looking Ranger. As if your not impressed already, this beautiful piece of engineering gets an astonishing average of 31 mpg. Hello dream daily driver. (2 videos below be sure to watch both!)
