Here's Why the 5.9L Cummins is one of the Best Diesel Engines Ever

The 5.9 Cummins will out live all the new fancy models

I’m 15 years old and next year I’m getting my grandfather’s old 2003 Dodge Ram 2500, with the 5.9 Cummins. Can’t wait

I like how one person painted theirs yellow 😂 strange looking Caterpillar you got there pal

Good friend of mine has a 1994 dodge 12 valve , Pulls airstream campers all over the US still runs well at 574 k miles but very well maintained over the years !

Well the 6bt was available is 160hp only in 94 and 95. Power jumped to 180hp for auto trucks and all California trucks 96-98. 215hp was standard for manual transmission trucks after 96. The bosch pump is a p7100 pump hence the nickname p-pump. The dodge chassis was all new in 94 and way ahead of it's time. Ford still used front leaf springs, the dodge had a much more modern 4 link with coil springs. It is also considered the first "new body style" truck.

That yellow paint is sacrilicious! :3

Currently pushing nearly 700hp out of mine with 550,000kms on it. Fucking love the thing.

One of the finest motors ever

These are literally THE BEST diesel motors out there without question. Say what you will and argue whatever points you wish, the facts are as they will remain. They are the easiest diesel engines to work on period, they get the best fuel economy for what they are as far as heavy duty trucks go. They also have incredible capabilities that outdo even the modern station wagons with 4x4 and diesel power plants we call heavy duty trucks today. Are they perfect? Absolutely not, nothing built by human hands will ever be perfect. But the reliability of these engines is what makes them so incredible and sought after. You can build one of these things into a 24 valve for added efficiency and power. You can build one of these into an absolute demon killing race motor that'll even stomp out Lamborghinis and Ferraris in certain cases. Or you can just simply have a daily dependable driver that will last you all your life and even some of your children's lives. That's what I'm getting mine for.. well, that and to make money hauling things.

I bought (6) 5.9 12 valve complete engines shipped for $5950 back in 2014 with P7100 pumps on all of them. (2) have 215hp pumps , (3) are the 180hp pumps and (1) has a 160hp pump. I think I did pretty good.

Love the 6BT, long live the Fasttrack.

6.2🤝5.9🤝6.9: Being built for a purpose and serving it well

I worked at a Cummins engine shop 1997-1999. The 5.9 is a very durable engine and easy to work on.

The 5.9 CUMMINS WAS NOT WEAK, it was Derated. Torque (horsepower) was limited, because a 1992 Dodge Frame rail twisted. When Dodge built a stronger frame & drive train, then CUMMINS Increased Torque. Other Equipment used the 5.9 CUMMINS had more RATED Torque.

I'm a ford guy but I love and respect the 5.9 game changer

If you know a thing or two about Cummins CPL’s you can build a 6BTA to 230HP and 620 lb-ft with all factory parts and Cummins factory settings. The CPL for that rating is 1553, you order the camshaft, have your P-pump set up for that CPL (bigger delivery valves, 13mm iirc) and order up an HE-351 turbo, and you’ll have an engine that really pulls and will still last 3-500k miles or more, you can even bump the fuel a little and get closer to 300hp / 650 lb-ft and not really give up any longevity. Keep in mind those numbers are on stock governor springs at factory rated speed…meaning all that power is under 3k RPM….and you know it’s a safe combo because Cummins built them for medium duty trucks and fully warrantied them back in the day. You can certainly make far more power with aftermarket stuff but you’ll be messing around with turning the engine well past 3,000 RPM, compound or big single turbos, etc etc and what most guys don’t tell you is a 500+hp / 800 lb-ft+ 12 valve will never live to 3,4 or 500k miles or more like a stock one will. They’re great engines but they’re 359 cubic inches and you can only push them so hard before longevity starts to suffer.

These are diesel engines! A guy should always include the torque rating!! Regardless of Horsepower you would soon realize that the Cummins is actually able to pull considerably more than the 1990 7.3 IDI due to its impressive torque figure of 410 foot-pounds for gen-1 compared to Ford's 338 lbs/ft and the 6.2 having only 234 lbs/ft

The 6BT was designed in conjunction with JI Case to be used in ag equipment

My cousin is a diesel mechanic, he says the 5.9 is much more reliable, it has half of the parts in the top end and compared to a 6.7

I've got a 78 k30 3+3 with a built and cammed 12v infront of an allison 1000. It will outlive every single new truck in existence. Love the 12 valves.
