12v Cummins Horsepower/Torque vs Model Year Graph

The Cummins 6BT was introduced in 1984 as an application in Case agricultural equipment. The engine uses a heater grid mounted beneath the air horn to assist with cold starting. This method is an alternative to the standard glow plug system, which relies on an individual glow plug mounted within the combustion chamber of each cylinder. If an engine is difficult to start, especially in extremely cold conditions, the heater grid is likely the culprit. The 12v Cummins has developed a cult following in the diesel motorsports scene, due in part to its simplicity, reliability, strength, and performance potential. Its relatively short width and fully mechanical design make it a popular choice for engine swaps and diesel conversions, as it is amongst the easiest engines to shoehorn into a compact engine bay and aftermarket support is high. The 12 valve's Achilles heel is what has come to be known as the "killer dowel pin" - a dowel pin pressed into the front of the engine block during assembly commonly backs out of its hole over time, which, in a worst case scenario, can wedge itself between the timing gears and create a chain of events that ultimately results in catastrophic engine failure. Aftermarket solutions have remedied the problem by creating products that secure the dowel pin in place so that it may not vibrate loose.
