Alright i want either a 6.5 Turbo Diesel or a 1995-1999 12v Dodge cummins, which truck stock would get better fuel mileage. Thanks, they woudl be ext. cab short bed too

 

cummins hands down. longer lasting, great fuel mileage if ur easy with ur right foot. plus wayyy more in the way of aftermarket if u ever wanna get some more out of it. just watch the auto trans in the dodge. they're weak. i burned thru 3 on a stock engine before i switched to the 5 speed

 

Please dont buy a 6.5 They are very weak motors just in stock form. Cummins all the way on this specific question.

 

I had a 95 6.5 before I bought my 97 5.9. My 6.5 turned itself into a V10, without any mods. Never beat on it. If you want a engine that will last, buy the Cummins. Best engine ever put in a pick-up.

 

what kind of mpgs are some of you getting out of the cummins and how much would it cost me to put in a manual trans?also cummins 95, wat lift you got on that? thanks

 

id choose the cummins by a country mile.my 95 12valve stock was getting 18mpgs

 

My 94 5 speed truck, on a 486 mile tank my gps said I averaged 32 mph and I got 15. On a 530 mile trip non-stop trip averaging 70-75 by my gps i get 16. Both my styles of driving kill fuel mileage and on top of everthing else I have a POORLY tuned afc, and 5x.014's.

 

How much does it cost to put a manual tranny into a auto tranny truck ?

 

Depends on a huge variety of things. I cant answer that but you have the option of doing it yourself, having someone do it, cost of parts, etc. Lots of variables

 

well, having someone else do it for sure im not very good with motors and stuff like that and the cheapest way in parts probably.
