I'm trying to find out how much of a pain in the rear it's going to be swap my 4.7 liter out for a Cummins diesel id like to use the 5.9 turbo diesel but dont want to cut up my engine bay to much in my 02 durango.... any words of advice for me

 

the 5.9 is going to be too long to fit int he durango without modifying the firewall, more common is the 4bt (3.9l) 4cyl cummins in the dakotaland, iv never seen one in a durango, but the engine bay is the same so if you fine a dak you have the instructions you need.

Good Luck
