Myth Busters

  • Myth: Industrial 4BT engines cannot be modified for on-road use.
    Reality: While these versions, many of which are derived from gen-set applications, are often outfitted with a constant-speed injection pump, this should not deter you from purchasing an inexpensive take-out 4BT. Any respectable pump shop may adapt the pump’s governor section to variable speed operation (as necessary for on-road use). Another difficulty is turbo location (high or low mount), which is normally for packaging reasons but can be readily resolved with an exhaust manifold flip or replacement
  • Myth: The 4BT is too loud and rough for everyday use.
    Reality: Modern mounts and sound-dampening materials can significantly reduce noise and vibration. Upgraded exhaust systems also contribute to a quieter operation.
  • Myth: The Cummins 4BT is solely for industrial applications and isn’t meant for automotive use.
    Reality: The durable nature of 4BT makes it popular in industrial and agricultural equipment but it has successfully been adapted for automotive use as well. Its simplicity, reliability, and fuel efficiency make it a popular choice for off-road and overland builds.
  • Myth: The Cummins 4BT is too heavy for engine swaps in lighter vehicles.
    Reality: While the 4BT is heavier than many gasoline engines, it’s not prohibitively so. With proper suspension upgrades and modifications, it can be successfully swapped into a variety of vehicles, including Jeeps, small trucks, and SUVs.
