1994-1998 2500 & 3500
This is the truck that put Dodge back on the map in 1994. The all-new Ram body style did most of it, but the 5.9L Cummins was there to make sure it delivered. As far as performance potential goes, it doesn't get any better than the mechanical P7100 equipped versions of the 12-valve 5.9L Cummins.The longevity of a cummins depends on preventive maintenance. The more you take care of it the longer it will last. They hold power well and if monitored properly will last longer than you will. Average mileage is between 17-22 depending on configuration and how you drive.
6.7L Engine for RAM
The Cummins 6.7L Turbo Diesel is the most powerful engine option for RAM 2500 and 3500 pickup trucks. Producing up to 400 horsepower and 1,000 pound-feet of clean diesel torque, this powerhouse helps RAM deliver best-in-class towing.But undeniably, of all Cummins pickup truck engines, the 12-valve 5.9-liter is the king. Cooper from Diesel Power Products says “It's probably the most reliable platform ever made on any diesel truck.”
No, the 5.9L( 360 gas )Dodge engine is not one of the sludge prone engines. The 4.7L is the main V8 while the 5.2L( 318 ) had some issues as well. A few V6's had some major issues( 2.7L especially ). The 5.9L/360 is actually a good engine.
The most reliable diesel engine ever made was the 5.9L Cummins 12-Valve 6BT. The 5.9L 12-Valve has million-mile durability. It came factory with a 230hp, 440lb/ft of torque and an inline P7100 injection pump.
The Cummins is so good because it was designed to be a very strong engine for industrial use. Designed by Cummins for that purpose and not just to be in a horsepower race and fit in an existing pickup truck. Cummins, unlike Ford for example, is interested in making engines that are durable.
The engine may last forever. The DODGE (or maybe Cummins) website speaks about the TD lasting 350,000 miles (mean) between overhauls, 100,000 miles longer than the GM or FORD.
The 12-valve went away in 1998, replaced by a 24 valve which offered better breathing. But undeniably, of all Cummins pickup truck engines, the 12-valve 5.9-liter is the king. Cooper from Diesel Power Products says “It's probably the most reliable platform ever made on any diesel truck.”
The last generation 5.9l Cummins engines from 2003 to 2007 used HPCR pump and 24 valves. They have 305-325 HP and 600-650 lb-ft of torque. Cummins made a displacement change in 2007.5 to the 6.7l Cummins diesel.

What made the Cummins so popular was the fact that its peak power and torque was insanely usable—in fact, the redline is only at 3,000 RPM! The 12-valve was able to get respectable fuel economy while producing torque figures never-before seen in an ordinary pickup truck.
The stock head bolts should be good up to about 45psi back pressure, and 38 psi boost.
In my humble opinion, the 68RFE is a solid transmission in stock power mode. Some users have reported at least 200K or more miles out of them with proper maintenance. Now the 68RFE auto can handle 60+ horsepower increase without any major issues.

Low boost fueling is the level of fuel that will be dumped before you build enough boost to burn it. That's why the smoke. The response you will feel. Go ahead and play around with it.
In 2007, Dodge trucks began using the 6.7L common rail Cummins diesel turbocharger engine, which uses a Variable Geometry Turbocharger (VGT). On the 6.7L, the VGT has a patented one-piece sliding nozzle that continuously moves to vary the power of the turbine and the amount of air delivered to the engine.

Method-1: By Removing Intake Baffle
Removing the intake baffle from inside the engine turbocharger can make your Cummin louder. It's the best solution to hear the turbo sounds. It is a plastic hose wrapped with foam. You can find it inside the turbo hose clamp.SIX-SPEED AUTOMATIC TRANSMISSION

Their high horsepower and torque outputs directly compete with Cummins engines, as well as PowerStroke. In addition to durability, Duramax engines are known for their quiet performance. The Duramax LP5 in particular is 38% quieter than previous versions.Both the 6.6L Duramax and 6.7L Power Stroke are V8 engines, with the 6.7L Cummins being an inline six-cylinder diesel engine. Horsepower and torque numbers are similar between the three diesel engines, but the Cummins engine leads the pack with its torque rating breaching the four-figure threshold.

Leadership position in the engine market counts among Cummins' (NYSE:CMI) most crucial competitive strengths. It is the world's largest diesel engine manufacturer, and powers most of the trucks that run on North American roads today.
Cummins set the record straight in their May 2013 newsletter, outlining that Ford Motor Company had purchased 10.8% of the diesel engine manufacturer in 1990. In 1997, those shares were bought back, and as such Ford has not owned a stake in Cummins since.
The Cummins 6.7L inline-six turbo diesel is offered in two variants; standard output 370 horsepower (850 pound-feet of torque) and high output 400 horsepower (record-setting 1,000 pound-feet of torque).
Diesel fuel historically has been more expensive than gasoline. This is attributed to three factors: Taxes: Diesel fuel is assessed a higher federal excise tax than gasoline (24.4 cents per gallon for diesel vs.
