1999 Dodge Dakota Diesel Conversion

Before

After

Well, here we go again. You may already have visited my Jeep diesel conversion page at http://www.canev.com/Jeep.html The Jeep was a difficult and time consuming conversion due to limited space for the diesel and its related hardware. As I state on my Jeep page I don't do this for a living and cant help you with parts or technical information on any conversion you may want to do (unless its to electric power: http://www.canev.com.html ) I do like to here what other people are converting and always have time to chat about it. :)

The truck is a 1999 Dodge Dakota club cab 4X4 with a V6 gas engine and automatic transmission.

The engine is a 2000 Isuzu 4HF1 normally aspirated 4L out of a NKR 3 ton truck. The NKR was never imported into North America except for a few "demonstration" vehicles, it is a smaller version of the popular Isuzu NPR which uses basically the same engine only with a turbo (which may find its way onto my engine down the road).

The first problem I encountered was the starter on the Isuzu is a rear entry so it was going to end up just about where the gas pedal is supposed to be. I built a 3.5" body lift and a small bump in the floor behind the throttle solved that. The engine mounts worked out quite nice and only had to build them once unlike the Jeep where I had about 4 mounts built before settling on a design.

The front differential is a problem at this point and I will leave it out for the first test runs. It interferes with the oil pan, I could pull the pan and modify it in the future but for now I just want to get the thing running.

While the cab was unbolted for the 3.5" body lift I rolled the from out from under it for a new coat of paint.

When adding the 3.5" body lift I found the steering shaft was then too short, A tour of the local wrecking yard turned up a Jeep Cherokee shaft that was long enough to do the job, it even used the same U-joint so it looks totally stock once installed. Next picture is of the new passenger side motor mount welded in place.

The truck has been on the road for almost two years and has been great.
The turbo really perked up the performance.
Its been our shop truck and used mostly for towing a car trailer for delivering our electric vehicles.
I never did put the front axle in so it has been a two wheel drive all this time. The fuel economy (26 mpg) is not as good as the Grand Cherokee (43 mpg) diesel swap that we did but I think that is because of the Dakota's automatic tranny and larger engine.
I just picked up a 2000 Dakota Quad Cab and will begin a diesel swap in the new year.
It has a 5 speed standard so I'm hoping for better fuel economy and may try SVO (Straight Vegetable oil) once its finished.
