Which year 12 valve Cummins is best?

1996-1998 has the best injection pumps (perhaps ignoring the 1989-1993 VE) and stronger automatics compared to earlier years. Look at the buyers guide section in the thread below. The 1998 12 valve trucks were only built in 1997.

What years did Cummins make the 12 valve?

1989 - 1993

The Cummins engine had been successful in agriculture implements for a few years prior, so in 1989 Cummins and Chrysler introduced the 12 valve as an alternative the the V8 gas powered Dodge. It was a hit immediately for those that wanted double the torque and a better option for fuel economy.

When did Cummins stop making 12 valve?

Cummins produced the 5.9L 12v Cummins for Ram pickup applications through the 1998 model year, where it was phased out in favor of a more emissions friendly 24 valve platform.

When did Cummins go from 12 valve to 24 valve?

By 1998, emissions regulations necessitated the switch from the 6BT “12-valve Cummins” to the ISB “24-valve Cummins”. Although the 24-valve was more powerful than the 6BT and was, by all means, still a very good engine, it never achieved quite the same popularity as the original 12-valve.

How much HP can you get out of a 12 valve Cummins?

Adding a P7100 to the first generation 12-valve engine effectively takes the truck's horsepower capability from 350 rwhp to 600 rwhp. For those kinds of gains it's definitely worth the hassle of hunting down all the conversion parts you need.

Are 12 valve Cummins reliable?

The Cummins 12v/6BT is widely regarded as the best and most reliable diesel engine ever produced. These engines are extremely simplistic, operating with mostly mechanical components rather than complicated electronic ones. The simplicity allows for massive power potential in conjunction with ultimate reliability.

Is the 5.9 or 6.7 Cummins better?

The 5.9 Cummins offers a fixed geometry turbo, which differs from the 6.7 Cummins variable geometry. ... To sum up, the more simplistic 5.9 fixed geometry turbo means that while it tends to be more reliable, the more advanced 6.7 variable geometry turbo gives better performance.

Is Cummins 12v or 24v better?

12v vs 24v Tuning & Aftermarket Potential

When it comes to serious power and performance the 12v 5.9 Cummins takes the win. These engines are known to hold up better at extreme power levels when compared to the 24v engines. P7100 injection pumps on the 6BT are easier to mod and support the extra power.

Are 12v and 24v blocks the same?

Registered. One difference that I know of is a 24v block has two oil drain provisions cast into the block near the pan rail and a 12v only has one. Minor difference, but different none the less.
