2008 Dakota / ISB170 Cummins conversion:

This 08 Dakota conversion was a challenge. The Cummins is just so much larger the the 4.7 and getting the ECM of both engine and chassis to function properly took a lot of work.

Old gas motor sitting beside the Cummins ISB170. The Cummins is a lot taller than the 4.7 V8.

We replaced the automatic transmission with a brand new NV4500 and with a little machining made an Isuzu bell-housing couple it to the Cummins.

The Cummins was a tight fit and the front diff had to be lowered by about 2". Had to do a 3" body lift and 1 1/2" leveling kit in order to fit it all underneath.

The body lift allowed a storage box to be built under the rear seat as well as a place to put the 12 volt battery since the engine compartment is full. The Dakota has very limited storage so its a very handy box.
