So, still three options for a diesel swap on a Jeep?

  • Cummins 4BT (heavy, but reliable)
  • VW TDi (light, but a little weak in stock form)
  • Mercedes (the 3.0 straight six is similar in weight and power to the Jeep 4.0 straight six)

In the 1980s, Ford and Mazda offered a 2.2 diesel as an option in the Ranger and B2200, but they are not easy to find and are on the weak side in power. The weight and power are similar to the four cylinder engines that were used in the early (flat fender) CJs. Ford bought the engines from Mazda, and Mazda was making the engines under license from Perkins. I think it would be a decent swap for a relatively stock flat fender CJ (if you had an engine and a CJ-2 or CJ-3 project), but I think it would be too weak for anything newer than that.

There are also some Kubota swaps, but those also seem to do better in lighter Jeeps, probably CJ-5 and earlier.

I think the YJ/TY Jeeps are likely lighter than the CJ series, puny frames and axles.

But don’t know the actual weight differences.

From a quick search, stock YJs are around 3,000 pound curb weight, with Stock TJs being a few hundred pounds more. Stock CJ-2 and CJ-3 were around 2,100 to 2,200 pound curb weight. Stock CJ-7s were in the neighborhood of 2,700 pound curb weight, with stock CJ-5s being 100 to 200 pounds lighter.

Year and options can result in quite a bit of variation in curb weight as you move toward current years, due to changes in the amount of options offered and additional safety and emissions requirements from the government.

Edit: The 1980s Ford Ranger pickups were a few hundred pounds heavier than the CJ-2 and CJ-3 (flat fender CJs), so the Mazda/Ford 2.2 diesel should perform better in them, than it did in Ranger pickup. …if you can find an appropriate 4WD transmission to adapt to it. Ford and Mazda used a transmission specific to the 2.2 diesel (Mazda did put a fifth gear on their transmissions, while Ford thought four gears was enough), and it was 2WD only.
