Making modifications to a expedition vehicle is no new idea. For years people have sought out the improvements on stock vehicles where the manufacture had left potential failure points or design flaws. Recently there has been several experts speak up for the most ideal modification you can make that promises to solve every problem that has ever existed for an expedition vehicle. Underland Journal has the scoop with this weeks Expert’s Corner.

Underland Journal caught up with popular forum blogger Cummins4BTurGF, an expert in the matter.

Underland Journal – What aspects of performing a Cummins Swap do you feel improves the vehicle the most?

Cummins4BTurGF – “The popular inline 6 cylinder diesel, known as the 6BT, is hands down the worlds most reliable motor. It has tons of power and can tow a house. It’s simple and bullet proof.”

Underland Journal – How do you feel your your Cummins Swapped vehicle has improved on these characteristics?

Cummins4BTurGF – “Well, I haven’t actually swapped in a Cummins into my rig. I’m planning on it. I look at marketplace everyday trying to find that unicorn 90’s truck that was rear ended with the motor and drivetrain intact. But I know it will be sick when I get it built.”

Underland Journal – Are there any recommendations you would make to adjust for the additional weight of a 6BT Cummins? For example the stock 190 hp 6BT engine weighs approximately 1200 lbs, while a 300 hp stock 6.0 LS motor weighs approx. 450 lbs.

Cummins4BTurGF – “Well, there’s more to things than just horsepower. The torque is where it’s at.”

Underland Journal – Torque, that a valid concern. The additional 750 lbs and less power is a net benefit. Especially when attempting to traverse snowy or sandy conditions.

Cummins4BTurGF – “It’s probably the best choice you can make for improving reliability. I really don’t see why people are swapping a Cummins into their rigs more often. The 6BT only needs one 12VDC wire to turn on.”

We wish Happy Trails to Cummins4BTurGF and the best of luck on their engine swap. We know that it will go extremely smooth without any hitches in the end yielding a superior product for overlanding. It will likely cost less money and that benefit of having 750 additional lbs on the front end will increase the traction in the rugged terrains ahead.
