My long term hope is to make a vegi-oil tow rig out of a 109 project I'm playing with. Looking for good millage, longevity, the ability to run multiple low grade fuels and hold 75 up hill. Not looking to make a hot rod.

With that in mind, a friend of mine practically gave me a mid ninety's heavy duty dodge ram with the Cummings turbo charged 6 cylinder in it. Quite a power house but I don't know too much about it other than the weight which is supposed to be around 900 lbs. The dodge truck has about 140,000 miles on it but seems to run well. However, still this may not be the best motor for the job...

Anyone know what the weight of the 2.25 lump is?

My first concern is making the truck unstable by making it too heavy in the front. Drive train and shoe horning would come later.

Hey Tim,

The shipping weight of a 2.25 petrol is about 750lbs. I'd figure about 50lbs for the crate, packing materials, etc.

contact Ike Goss I think I remember him saying he'd seen or he had a 109 with the Cummin's 6cyl diesel. I think the Mid to early 90's engines are the better choice for swaps, due to their Injection pump etc. I can't remember all the details- I never found one I could afford.

Here is a page dor diesel swaps in m-37 power wagons, generally they have more room? Don't know why he doesn't think the Cummins 6 will fit. Interesting info nontheless:

Here is a site with info geared towards Toyota Land Cruisers, some info on cummins 6at:


The dry weight of the Cummins 6BTA5.9 is 905 lbs (no flywheel, clutch or any accessories).

and from TAW's page:http://www.expeditionlandrover.info/enginePwrSpecs.htm

MB is getting some 200 tdi motors in soon.

Thanks for the great info on Cummings swaps. This is really helpful stuff. I'm thinking that the 5.9 liters of raw chugging power is probably too much for what I'm looking for.

As for 200 tdi's, I'll take 3. One for each of the two projects I'm playing with and one to hug at night after a long day...

the 5.9 might be too much but "how much is too much?" ;)

it would be the basis of a neat if rather involved project.

here is a 4bt in a 109:

The Rover 2.25 is definitely a heavy little motor... in the 650-700 lb. range. The Cummins used in Rover swaps is the 6AT, NOT the 6BT (as found in the dodge pick-ups). It has a smaller displacement compared to its bigger brother (the 5.9). Besides, I'm pretty sure the 5.9 weighs in excess of 1000 pounds or more, depending on model.

The 6 cyl is a much smoother running motor, compared to the 4BT, which is a great motor from what I've heard but is very tall for a rover swap and very noisey/rattly. Just for some bigger diesel options, look into the Isuzu 4BD1 or 4BD2... a VERY reliable quieter 4 cyl diesel (used in the very common Isuzu NPR trucks you see driving around all over the place), 3.9 Liters, manual IP pre 1994-ish, easy to find, becoming more affordable, great parts availablilty, turboed and intercooled. I have one for a potential future 109 project. Only PITA is they have a rather unique bolt pattern, so mating up a "commonly used" tranny, like the 5 speed NV4500, etc. is tricky/expensive. Sounds like the the thing to do is use the Isuzu 5 speed tranny used for that motor, and adapt the Rover T-case up to it. The Isuzu tranny is a great box.

Hope it helps!
