Basically the 4 BT is just the same motor found in our trucks with 2 cylinders cut off. a very strong reliable engine that is capable of some decent horsepower with some mods depending on what injection pump the engine has. The "Diesel Power" magazine had a feature on a 4BT in a jeep putting out 400 HP so its quite doable easy to do. hope this helps
