This is my first post. I am very new to diesel motor let alone cummiuns. Ever since i heard about the 4 cylinder cummins motor i wanted to put one in my bronco. My bronco has a custom state of the art frame a dana 60 in the rear and a HD dana 44 in the front. I really want to put a 4bt in my bronco but ihave no clue where to start. What should i look for in a used 4bt. What do i need for this swap. I am new to diesel so any help would be greatly help full. I have a 1987 ford aod trans but not sure it is strong enough for the 4bt. Also what is the difference between a 4bt and a 4bta? Thanks
