8.3 Cummins

Who has turned up you 8.3 cummins, and what do you like and donít like about the results? Is it worth doing? Is there a lot of work involved, still would like to keep all my exhaust intact, and want it to be just as dependable as it is stock.
Thanks.

The 8.3L Cummins in a mDT means 10k or more added to the price. They are very sought after. Seen quite a few turned up and they live long and roar. 2012 not sure about the electronics but the older one really put out the torque.

Nothing much can be done to increase HP without also improving/enlarging the exhaust system, and still retain reliability. 1,380įF exhaust temperature is the point at which valve begin to melt if the hot exhaust gas it not quickly evacuated out of the cylinder.
Just visit some of the diesel websites for pickups and begin reading,especially about the Cummin's B series engine, which-FWIW is the only medium-duty diesel engine used in a pickup.

Ray in is right on this if you want to turn it up you have to get rid of the heat quickly. Larger exhaust and open mufflers help also wrapping the exhaust so the engine bay stays cooler helps also. Good friend did this to his medium duty frt liner and then went and put an air damn in to push more air through the engine bay, it seems to work quite well and he is happy with it. He pulls a racing trailer with it and has plenty of power and it does run a little cooler than it did but you can hear him coming down the road it is loud.

I was looking up the same thing last year. I couldn't find any current offerings.


All I found is that Banks used to have a kit for it: https://www.xtremediesel.com/banks-p...owerpack-49297
