One of the coolest engines ever produced is the 4BT Cummins, in all of its variations.

You may be wondering why we would be touting a teeny 3.9L, four cylinder engine as one of the coolest engines? Well that’s simple. This little diesel can be swapped into numerous vehicles that simply don’t have the sheer engine bay space for any of the traditional larger engines, let alone the weight. Further, the earlier mechanically controlled engines could be modified to produce impressive horsepower numbers, while still achieving over 40 miles per gallon.

In one of our in-house builds, we took a 2009 Jeep JK four door and slapped a 4BT in it, along with a host of other off road oriented upgrades and made one of the coolest JK’s on the planet (at least we think so). That Jeep took us all over the country on some of the toughest trails you can imagine, and still served as a vehicle that could easily be daily driven, turning heads everywhere it went. It's hard to not look twice when you hear a Cummins rattling under the hood of a Jeep rolling on 40” tires!
