Cummins is one of the world’s most well-known diesel engine manufacturers. Many car enthusiasts are familiar with the engines used in Ram trucks.
Part of the success of diesel pickup trucks can be attributed to the 5.9L Cummins engine. This engine has received a few updates over the years. The 5.9L is available in two different versions: 12 valves and 24 valves. This article compares the two 5.9L Cummins engines and their benefits.
12V 5.9 Cummins
This generation of 5.9L engines had better emissions and performance than the previous generation, thanks to a new turbocharger, injectors, and pistons.
The 12-valve 5.9L 6BT Cummins appeal to its simple design, unmatched reliability, and tremendous performance potential. The Cummins 5.9L 6BT had 230 horsepower, 440 lb-ft of torque, and a P7100 inline injection pump.
Advantages of Cummins 12V
The simplicity of the 12 valves 5.9 Cummins engine is one of its main advantages. The engine was created before the advent of infinite electronics and complicated systems. Cummins 12V engines use a P7100 injection pump, which is believed to be more reliable than the 24V Bosch VP44 injection pump.
24V 5.9L Cummins
The ISB engine offers greater stock performance ratings and the option to tune the engine with a handheld tuner.
The engine began using a Holset HY35W turbo in 2000, which featured a more restricted exhaust arrangement. The engine produced 215-235 horsepower and 420-460 pounds-feet of torque from 1998 to 2000. The 24V’s output grew to 235-245 horsepower and 460-505 pound-feet of torque in 2001 and 2002.
The 24V engine was also available in a high-output version from Cummins. The high output 24V 5.9 produced ten more horsepower and 45 more pound-feet of torque than the standard version while paired with a New Venture NV5600 six-speed manual transmission.
Advantages of Cummins 24V
Cummins engines with 24 valves are still fantastic all-around engines. For one thing, it produces more in stock form. This is an important consideration for individuals who do not want to tune or modify the 5.9 Cummins engine.
Because the 24V is a modern engine, it may not require as much maintenance. Chiptunes are also possible with the addition of electronics for 24V Dodge Ram trucks, making tuning a little more straightforward.
12V or 24V Cummins?
Those who seek high-performance statistics may prefer the 12V variant, which can approach 1,000 horsepower with minor adjustments. On the other hand, the newer 24V might be better for people who wish to make changes using a handheld tuner. Also, those intending to maintain their truck as original as possible may prefer the newer 24V engine.
The newer Cummins 24V 5.9 (ISB 5.9) is still a good, reliable diesel engine with a few advantages of its own When comparing the 12V and 24V Cummins engines, the newer Cummins ISB 24 Valve Engine has significantly superior bone stock performance.
Both versions of the 5.9 B Series Cummins engine are pretty reliable in terms of reliability. Both the 12V and 24V have a decent chance of making it to 300,000 miles with regular maintenance.
Both are over 14 years old, requiring routine maintenance and repairs. The ISB 5.9 24 valve diesel engine, on the other hand, has a significant age advantage. Because of its age, a 2007 ISB 5.9 engine is expected to be more reliable than a 1995 6BT engine.
The 24V engine is still the preferable alternative for individuals wishing to keep things simple with a tune and modest bolt-ons. It’s easier to tune because the electronics support “chip” tunes. However, for those willing to push the engines to their limits, the VP44 injection pump is a huge snag.
The 12V 5.9 Cummins wins when it comes to significant power and performance. Compared to 24V engines, these engines perform better at high power levels. On the 6BT, the P7100 injection pumps are easy to modify and support the higher power.
Which Is the Better Option?
Cummins engines are unbeatable in terms of dependability and performance. Whether the 12V or 24V 5.9 Cummins is superior or not isn’t always easy to answer. Both engines have a lot of potentials if you add a bigger turbo, and they may be used as tow vehicles or daily drives. Which one is better is a matter of personal preference. It all depends on what you want to do with your light-duty truck, as there is no clear winner between the two.
