Diesel Dakota conversion

I currently have a Dodge Dakota with a 360 V8 AWD. I'll admit I like the motor but I don't like the MPG, I get 11 mpg on the highway and around 9 around town. Awful is the only way to describe it, my treehugging side feels guilty at times. Anyway, all joking aside I was thinking about putting a Duramax in the Dakota. Here's the plan:

1. Find Durmax with wiring harness and ECM

2. Find Allison transmission

3. Remove V8, tranny and transfer case. I would like to keep the AWD system but I think that might be more trouble than it's worth.

4. Install motor and tranny and custom driveshafts.

It sounds simple.

I was thinking the Duramax would be the best fit since I already have a big V8 in the Dakota. I need to get some measurement but I think it will fit. I was thinking about running two wiring harnesses in the truck. It may sound odd but it saves me having to splice a bunch of wires. Have a stand alone system for the motor and leave the original wiring harness for the rest of the truck.

As far as the tranny goes I think it will be fairly simple. I'm sure I'll have to make some crossmember modifications and take the driveshafts to get new yokes welded on.

It is going to be some work, but I think it will be possible. The big challenge will be making it look factory but I have a feeling it will look like something Frankenstien left in a toilet. I would like to hear inputs on this as far as engine choices etc....comments good or bad. Thanks

that still seems like alot of motor to cram in there. maybe a cummins 4 cylinder would work best for that small of a truck

There's a few guys in Canada that have Cummins 5.9's in Dakotas. The transfer case & drive shafts add to the expense, but really helps traction in all weather.

I think there is a guy on base here that has a Cummins in a Dakota, but I never have the chance to stop him.

Going for mileage? VW-TDI at much less cost and much more balance. Not enough HP? Blu-tec 3.0 from the new Jeep. A lot more trouble to find one for repower and a little more expensive but better matched to total vehicle weight.

Duramax leaves no cargo capacity on the front axle. 4BT is about the same as the 360. Perkins has some that are in the good choices for weight.

TDI will probably cruise over 80 mph and may get as high as 45 mpg. With a chip may be close to the 360 for torque.

I agree the dmax might be too much for the front axle to hold. If you really want to go the dmax route you better plan on finding a D60 for the front and a heavy duty rear for the back. I doubt the factory front will hold it let alone the torque side of it.
