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

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.

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

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 !

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.

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.

One of the finest motors ever

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

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

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.

That yellow paint is sacrilicious! :3

Love the 6BT, long live the Fasttrack.

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

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.

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

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

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

Painting a Cummins yellow is blasphemy. Lol!

The 5.9 is not weak for today standards😂

I still remember my Dad buying his new 1992 Ram 3500 dually extended cab 5 speed. It was $21,500 out the door. He wrote a check and that was that. Say what you will about 160 horsepower. We pulled an 8 wheel 40’ gooseneck and it had no problem pulling huge loads. Another advantage to being “underpowered” was that it got 20+ mpg unloaded and even pretty good mileage loaded. We used an old F250 460 prior to that and it would do 8 mpg. Back then diesel was a good 20 cents cheaper per gallon and ran from as low as $.85 and as high as maybe $1.05 a gallon. The truck definitely paid for itself many times over

I was on the Leyland Vehicles product planning team for this engine back in 1983, helping specifying the British version of this 'world engine' project. Its successors are still powering leading vehicles in some European market sectors today.

I have several of them and I love them

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.

5.9 Cummins for ever 👌🏽💪🏽

I still have my drw 89 w350 I also have a compound charged 01 and a drw 6.7 08. What amazes me is how much in common the current 6.7 from 2023 still has in common with the 5.9 from. The early 80s. They may of stroked and bored the engine add different pumps and move valves but the basic architecture is the same.

Imagine what all of these companies could have done back then without the stupid EPA regulations. Imagine how far advanced all of us would be now. Am I the only one who's sick of the climate alarmist cult?

The fact you didn’t mention the 5.9 will pull 400hp and 1500nm of torque for more miles than a drivetrain will usually hold up before a full rebuild with NO ENGINE MODIFICATIONS except a big turbo and some governor springs shows you seem to know very little about it. Possibly THE the greatest diesels ever made.

Got an 03 5.9; truck is absolute chad

I love my 92 Cummins an don’t forget about the 6.7 Cummins 👍🍻

2000 ft pound torque insane.

Love my 5.9’s

The cummins 6bt was somewhat popular with tractor puller builds. Of course there were adapter plates to be made so the engine can be mated to the tractors backend

Best medium duty diesel ever made

See now, as an industrial diesel mechanic, I really feel that most people miss the point of the 6BT entirely. The reason this engine is such a strong platform is because of the original purpose of its design. It was designed and built to be an agricultural and industrial use engine which is meant to endure thousands upon thousands of hours of duty across a HUGE array of applications which have requirements that vary widely. If it had been designed with automotive use in mind specifically, the characteristics of this engine would undoubtedly be very different and would be geared towards performance and efficiency rather than dependability and efficiency. It truly suits a tractor far better than a pickup truck, but those that don’t understand this are likely hauling their groceries anyway. As for the rest of us, we don’t really care if it’s fast or not. We want to hook up to heavy stuff and move it from point A to point B again and again and again which the 6BT does VERY well. As it should. Also, there are several other engines that match or even best the 6BT, but you won’t find the majority of them in a pickup. Not normally anyway. 😂

it was bullet proof. We run those engines in all our service trucks and utility vehicles.

Not only that, that engine pulled Cummins out of bankruptcy, and it was an absolute unit in the industrial field, the mark that the 6BT made on the world was least significant in the automotive industry

I'm lucky enough to have one

my dad had a 6 speed cummins watched him pull some huge shyt with it too 😂🎉only problems it ever had was the axles cause the shyt he’d pull all the time but the motor ran like a champ and still does 😂

The straight configuration of the Cummins will always be the best engine design when compared to a V style engine. If Ford would make one it would rule the market. .

My 5.9 in my truck has 600k miles on it and is still going strong 💪

That GM 6.2 is an absolute slug. However, I think Banks has turbo kits for them and they're pretty fun once you do that.

love my 12v and my Toyota diesel 2lt

In my opinion the first dodges that got the cummins looked alot better then the newer ones I prefer the truck look

Got one of those 5.9 12v in my Case 888 :-) And my dad got one in hes Huddig 1160 to!. really nice engines!

whoever painted a 12 valve yellow can quit their job

My 97 Cali 7.3 has a sticker that says 220hp 😎

I call my RAM 2500 with the 12v P-Pump and hybrid. Its when a tractor and truck fall in love and have a child.

I've owned several diesel pickups from Chevy duramax to the Ford powerstrokes, but the dodge cummins will always be my favorite hands down. There is just something about the sound they make when they are idling. They sound like it's about to fly apart. I love em. Unfortunately, with the cost of fuel due to bidenomics I don't drive the one I have as often as I'd like.

I don't know a whole lot about diesels but I have heard a lot of good things about the fuel economy the torque and how reliable it is if maintain correctly, but I do know I'm not a big turbo fan so give me a good diesel engine with no turbo and I'm good to go

There are Many Good Diesel engines

The original commercial grandfather diesel of today's family truck diesels

I know people are going to hate this comment, but I believe the 6.7L Powerstroke is the greatest diesel engine ever put into a pickup truck. Unless you are trying to make 1000+ horsepower, it will get you there the easiest. It already has a ton of power from the factory. A stock 6.7L will generally last 400-500k miles, and a deleted one can make it close to, if not over a million miles.

The cummins is to the diesel world what the LS is to the gas world.

Unreal to think my 22 has 370hp and 850 torque, we have evolved

Yes that is awesome

It's not the horsepower, it's the torque.

I got a 92 with the bosch fuel pump in my schoolie.

You know what I like about this guy is he looks like he would know the least about diesel engines but everything he talks about I can confirm 😂👍

Was thinking of building one do you have any suggestions for what year to rebuild I was thinking like 96 or 97

the ram it was put in was period appropriate, because the truck was produced when the engine was, in the 80's.

Cummins is what saved dodge trucks. Also the first TURBO diesel in a pickup truck

The 5.9 had to be severely de-tuned because dodge didn’t have anything behind it that could hold the power. Look at machinery and boats that used the 5.9 and they make way more horse power compared to the dodge. They don’t call them shipping crates for nothing.

OM606! ❤

I own one of these trucks it’s a 98 the last year they put that engine in the trucks and I’ll tell you it has treated me very well since I got it and I got it for a amazing price compared to these new trucks. With the right upgrade to the engine I argue that the 12v 6bt would perform better and last longer than the new model Cummins

Contemplating a stock one with a ve pump in my 86F150. Not going for a whole lot of power. Just an upgraded turbo. As light as the truck is im not gonna need a bunch of power

the only drawback to the 6BT is the parent bore block......but thats only a small issue for such a prolific design.

I LOVE my 12 valve no DEF 5.9

Looks like somebody painted their Cummins cat yellow

Simplicity and solidity are the children of all ferrous metal componentry ! Skip the alloys. Go with the iron !

That Cummins is painted caterpillar yellow to not throw a rod 😂

Bro really thought a cat engine was a Cummins at the start💀💀💀

It’s simple as to why this engine was so great. It was built well but it could handle 2X the horsepower so they tuned it down. It now had hardly any horsepower so that’s means it’s going to last a long time. Due to the Duramax being such a large engine when it came out and more HP and torque this forces Dodge and Ford to build larger motors. The Durmax is still in operation after 25 years and I don’t see Chevy ever changing this because it works. They are known well to go over 500,000 miles and more.

Beautiful P pump

I got over 500,000 on mine myself and it has had a RUFF life .

Ladder frame solid axle leaf spring trucks are still the best truck chassis.

The best is the 8.3 210hp non intercooler most small 8.3,I have one in my country whit almost 3 million miles and just 1 time was rebuilt, is incredible amazing engine ever made because the 5.9 after 400 thousand miles problems starter, fuel pump issues or turbo issues, but the 210 non intercooler is something woww ,trust me good engine and no jokes still working to today, the block have small crack like just a little very little but is working 😂👌🏿💪🏿

The new 6.7 is pretty good too

It's probably too big and heavy but imagine how Ford could've changed the game if instead of the 7.3 they used the DT466 in the F350/Super Duty.

My moms pulling truck was a 5.9 it made like 600-700hp

Dad’s truck still see it on the road…1991 dodge dully…engine cylinder scorched at 95k miles…dodge replaced the engine…speedometer stopped years later at 285k drove it for 10 years after…had to have 500k+ on the truck…he passed in 2004….truck sat a few years, sold it to a guy who drives it to this day

cummins 5.9 liter is one of the best ones made by Cummins India Ltd. in India and best in class made in India till date.

The P pump aka the PP 😂

The only problem with those engines is that they weigh 1100Lbs. But they can wear out 2 or 3 chassis. They make the slant 6 look unreliable, wich they are not.

Wrong as a Detroit guy the Detroit 6.2l 145-165hp 380ftlbs torq. The 6.5 turbo made 180-210hp was 380-somewhere in the mid 450ftlbs

my stock 04 5.9 has the h/o motor and it makes 325hp

Which I could still get one of those out dated chassis new. Better then all the new bullshit.

You need a youtube short bro😁

They put the 5.9l Cummins in more than just Dodge Rams. I have one in my Ford F800. It doesn't have the p-pump. Hp numbers are only a small part of the story. My truck is rated at a measly 175hp, but it has 420ft/lbs of torque. If I could dial up the hp and torque, I would. 300 hp and 700ft/lbs sounds better and it would have an easier time going uphill. A ten speed bike is faster out the hole. That engine is, in my opinion, the best diesel engine ever made.

The 2JZ of diesel engines

Best part when it able to breath, leaving the shop 0-80mph haulin 60k of rock.......pricesless

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.

I’m 13 I’m getting my grandada 2012 Cummins 6.7

It sucks that there's no liners in the block

I've got one of these. 93 Dodge and with only 175000 mi. 5 speed. EMP ready...

The 6BT was an industrial engine while the 6.2 was an engine designed for economy and was an underpowered turd. The Cummins engine SAVED Ram in the 80s and many, MANY engines outlived the rest of the truck they were put in. I have one in a 1989 D250 that starts right up and has zero blow-by.

I drive a 6.7 liter Cummins engine school bus 🚌 and I have no problem but high exhaust temperature code that keeps coming on from time to time.

I’d love to find me an old Dodge 12 valve Cummins manual, I could make that truck last me the rest of my life anyway. No bells but a pretty decent whistle ✌️🇺🇸

The 5.9 is the only medium/ light duty engine that respectably compares with the 7.3 for reliability and durability.
