Part of the 4BT’s appeal for Wrangler owners stems from its packaging size. Whether you’re swapping a 4BT into a CJ, YJ, TJ or JK, we’ll cover all of that and more below. Mounting it, adequately cooling it, and deciding which transmission to use all take time-not to mention that supporting the 760-pound all-iron oil-burner will force you to take stock of your front suspension. But what’s involved in converting a Wrangler to 4BT power? After all, sourcing an engine is only the beginning. Once it goes between the frame rails, it’s not expected to ever come back out. For them, the 4BT solves several problems at once: they get gobs of low-rpm grunt, the mileage they lost with the install of a lift and bigger tires is redeemed (and then some), and they practically have to fabricate a reason to pop the hood.įor these folks, the 4BT is their forever engine. And perhaps no other group of enthusiasts has taken to the industrial strength 3.9L diesel quite like Jeep Wrangler owners. No wonder the 4BT Cummins has become one of the premier engines for swap projects. It’s durable, it’s reliable, it provides unmatched off-idle torque, and it can double a vehicle’s fuel economy.
