EZ Dodge Cummins Questions

Hi Rob.
Well.... its all subjective. Depending on how the vehicle has been treated and such. In its day the 6BT Cummins 12 valve was a good diesel engine. Reports of fuel mileage ranked anywhere from 20-28 mpg. When towing the mpg obviously dropped but alot were still seeing 15-18 mpg. The old Cummins was not a hot rod. Its actually rather soft when you put the steam to it, but it will get the job done... just not quickly. The simple upgrades that help the performance are simply done by opening up the exhaust system and a better air intake system. Spending money on injectors and all the other hoopla isnt going to gain you much for the bucks you will spend...other then create alot of black smoke. Another great thing to do on these it take them into a injection shop (preferably a diesel shop) there are tricks that can be done with the injection and timing that are merely adjustments that will significantly increase the power and make these diesels run alot better. Keep in mind 89 was the first year in the Dodge. If the truck is a manual trans, there may be some issues with the trans (if they have not already be addressed) and the other thing is the front suspension were soft and may need some work done on it.

Thats the basics and the knowledge I have. Hope it gives some insight.
