I got some pretty valuable information for you.... DONT DO IT! Its a waste of time and money. Cummins are not the reliable engine they are made out to be. you wil be frustrated daily with all the problems you will have. The only perks about them are relatively cheap power and fuel economy (assuming its a 12 valve your talking about getting) but if you dont treat it just right and i mean just right, you will have a have a huge paper weight of an engine on your hands.
