I hear a lot of people say they think the Cummins is a great engine, but they just hate that it comes in a D**ge. A lot of the guys with F**ds say they wish they could get their truck the Cummins. Of course, I guess that makes sense, with the mucho problems they're having with that new Powerstroke. But the Duramax seems to be a lot more reliable, so I wonder if any of the Duramax guys think the same thing. If you could get the nice Chevy truck, with everthing the same, including the Allison, but option for the Cummins instead of the Duramax, for the same money, how many would do it?Edited by: Brake_Torq

http://www.dieselplace.com/forum/smileys/Dead.gif Uh going to have to say NO!

I don't know. After owning my Duramax for almost a year, I think I would stick with the duramax. A year ago it's hard to say.

I work on a lot of diesel trucks. I would say if i had to haul monster loads to the point of abuse on a regular basis , Yes. I have a company that hauls boats across the country and all their trucks are Dodge. They average 20 to 30 thousand pounds per load and the CTD handles it well. The trucks on the other hand do not. They have some weird problems and dealers are of no help. (that sounded familiar) I bought my Duramax for fun and for testing , and i don't doubt that it could handle anything i could throw at it. Looking at the CTD crankshaft makes you respect the motor, it's as big as my leg, maybe bigger.

I had the best of both worlds from 1984 until I sold it in 1993. A 84 GMC 1 Ton 4X4 CC Dooly with a Case Cummins 6BTA installed by Cummins Las Vegas - the 6BTA came out before Dodge came out with the Cummins. In over 300,000 miles of use, many towing 43' gooseneck enclosed car hauler with 3 Porsches in it, the only engine problem that ever developed was the throttle cable fell out of its holder outside of Reno at 3am. Ran a Turbo 400 trans with dual Gear Vendor OD's - truck was awsome power (massaged by Cummins Las Vegas quite a bit), never ran hot, but I had a tough time keeping transmissions in it. Tore out a torque converter every 40,000 or so - got so we changed torque converters at 30,000 and didn't blow again. I doubt the Duramax will be as trouble free (has been for the first 60,000) for 300,000 miles nor as cheap to operate. The 84 got 18 mpg unloaded and a solid 13 mpg when you towed heavy. The D/A rides a lot better and is a LOT quieter, but doesn't have the towing guts in stock form the 84 did as massaged. The 84 is still running at over 500,000 miles pulling horse trailers and hay trailers and I have been told he still hasn't touched the engine. Favorite: D/A if no injector problems.

To tell you the Truth, I had more problems with the 98 D***e I had. In the first year I had it in the shop 3 times, it would loose throttle responce. Finally after I almost got hit they were able to figure it was something to do with the TPS. I havn't had my Duramax in for anything. I beleve the Duramax does a better job pulling my 28 ft. 5er. But a lot of that is due to the Allison Tranny.Edited by: BIGMoe

I LOVE THE D-MAX! It is the reason the others had to re-think their Diesel engines. It proved that GM IS a player in the HD Truck market.


2 years ago I would have said no way would I take the Cummins! It was just too loud for my taste. However now that they have come out with the "600" with loads of power, torque, and it is quiet!


On the down side, I hear the "600" has taken a hit on fuel economy. http://www.dieselplace.com/forum/smileys/Ermm.gifThat was one thing the Dodge boys used to brag about. I don't think the Cummins is perfect, But it is a great engine!


Yes, I would take the Cummins if it were available with an allison in the GMC, But it would be a VERY CLOSE RACE.

New Cummins with an Allison.....absolutely!!

I've heard all this balony about Cummins towing better but how? The h.p./torque that come off a dyno are real measure of avail. energy that the engine can supply. Do the numbers, the only advantage I can see is the Cummins makes it down lower, funny that GM just brought the max torque down two hundred rpms. The Cummins seems to have a clear advantage with hop ups.

I would have gone with the Cummins. Track record means a lot, and face it, Cummins has a long track record. Love the Dmax, but we don't know how it will handle the extended miles.

That's a good question but at what point? An older version of the 5.9 would be really nice for towing yet out of place in a quite GMC. The "new" Cummins with the Bosh rail is nice...but there again it's "new" to injectors as well. The "new" Cummins (meeting tier II compliance) fires "3" times per stroke and sucks fuel without an EGR. http://www.dieselplace.com/forum/smileys/Confused.gif So, to answer your question........ New 04 Iszzu Duramax Vs~ New 04 Cummins......... I'll go with the V-8 for 2 pulses, wider powerband and .... it sits in a much nicer truck.http://dieselplace.com/forum/smileys/Thumbs%20Up.gif





Burner----------> http://www.dieselplace.com/forum/smileys/Big Smile.gif

Well I haven't had the opportunity to drive the latest cummins, but from the previous versions if the new one is simailar I'd have to say no way! I found the others slower than mollasses in start and stop driving and since my truck is my daily driver that's no good. They have improved the noise level thankfully so that would help. But since my D/A has been good and is fairly quick I have no reason to wish for the inherantly slower inline 6.

I had a '99 5-speed 3/4 ton Dodge that was a great pickup but for the limited slip and the front suspension. I had an Edge on it just as I do on my 3/4 D/A with the flatbed doing the same farm/ranch work and I know the Dodge would outpull this D/A. It had a manual but load it down and it had LOTS of guts down low. I was just telling a neighbor the other day how much I love driving my D/A but if I could put a Cummins in it I think Chevrolet would have the perfect pickup.


So, I'ld go Cummins

If I walked into a Chevy or GMC dealership to order a new truck, & the saleman asked if I wanted the Duramax or the Cummins in it, I don't think I could turn down the Cummins. I came REALLY close to buying a D**ge with the Cummins in January, but I just couldn't talk myself into buying a truck made in Mexico. Plus, after 238,000 miles on my 2000 Chevy 2500 (6.0 gasser) with only replacing the water & fuel pumps & the alternator, (& that was after 200,000 miles) how could I not buy another GM truck?!
I should have 60,000 to 70,000 miles on the new LB7 by the end of the year though, so hopefully by then, I'll have changed my mind & would order a Duramax over the Cummins the next time. Sounds like I better get that secondary fuel filter ordered though!http://www.dieselplace.com/forum/smileys/Big Smile.gif

Well I don't know about the Cummins, but I would take a Caterpillar/Allison combo right away. Still love my Dmax thoughhttp://www.dieselplace.com/forum/smileys/Approve.gif

I'd take a 12valve Cummins with the 6-speed any day, even if it was $1000 more than the duramax. If the duramax was an inline 6 with the low RPM torque of the cummins then I'd reconsider.


With the automatic I don't doubt the duramax is the better of the two engines performance wise with it's longer torque curve and the transmission will keep the RPM's in the peak range but I hate driving a diesel engine near redline. Drive a cummins with the stick and you'll see what low end torque is all about. You don't ever need to go past 2000rpm no matter what you're pulling.

I would have to go with the Cummins, a lot heavier bottom end. I like my Duramax, but have really not had one long enough to take it over the Cummins.

Like I said.......for heavy towing I'd pick the Cummins. For all other applications I'd pick the Duramax.


...... I wonder...... if Cummins and Iszzu use the same injector... Could you put 2 pulse injectors or program the 3 pulse for 2 or 1? If it could be "programmed" for only one pulse the MPG would be GREAT!!!


Burner-----------> http://www.dieselplace.com/forum/smileys/Big Smile.gif

I loved the cummins in my 99 dodge. Decent mileage, and even better if you had the stick. However, I just talked to a fellow with a brand new 2004 dodge with the cummins 600 and he is extremely unhappy with the mileage. He said that he is getting 10-12 mpg in town unloaded and the best he has gotten is 15mpg on the freeway. Sounds like dodge/cummins have a real problem.

Caterpillar/Allison sounds good to me too.


Maybe a 3406E 15.8 Litre, 600HP, 2050ftlb of twist your driveshaft into a pretzal torque.http://www.dieselplace.com/forum/smileys/Clap.gifhttp://www.dieselplace.com/forum/smileys/Big Smile.gifhttp://www.dieselplace.com/forum/smileys/Approve.gifhttp://www.dieselplace.com/forum/smileys/Embarrased.gifhttp://www.dieselplace.com/forum/smileys/HiHi.gifhttp://www.dieselplace.com/forum/smileys/Hug.gifhttp://www.dieselplace.com/forum/smileys/Thumbs Up.gifhttp://www.dieselplace.com/forum/smileys/Tongue.gifhttp://www.dieselplace.com/forum/smileys/Cool.gif

The Cummins would be my first choice, even though I love my Dmax. I think the Allison, as tough as it is, would still have to be beefed up to take that bottom end torque.

When I test drove the cummins, I can clearly remember telling my wife "I dont think I will want to live with that noise" and that was the new quieter engine. Ive been driving mine a year and its a toss up weather i play the bose system or tune in on the engine later, bc

I love my Duramax http://www.dieselplace.com/forum/smileys/Heart.gif

Lets turn it around would you buy the dodge if it came with the duramax and the chevy had the cummins?????

NOPE


Geno

I have owned 3 Dodge Cummins. I have never had a problem witht the truck and not one repair to the Cummins after 100's of thousands of miles. If they could match this engine to the Allison, that would be one heck of a combination. I did not have to be concerned with any of the Cummins concerning fuel filters or modifications to protect the life of the engines. I would choose Cummins with an Allison.

No, I don't think so.


The major selling point to me was the quietness of the Duramax over the cummins. That, and the shear amount of power increase you can take the stock motor up to. I'm not planning on adding a juice any time soon, (that's what my wife thinks http://www.dieselplace.com/forum/smileys/Wink.gif), but it's nice to know it can be upgraded very easily.


Now, if GM can make the cummins as quiet as the Dmax and have plenty of overhead for power expansion.... http://www.dieselplace.com/forum/smileys/Approve.gif


But in total, I'm am extremly pleased with the Duramax power, Allison trans, and all setting in a truck that is getting compliments from Ford owners. http://www.dieselplace.com/forum/smileys/Big Smile.gif

I used a decibel meter on a salemans (Cummins marine) truck that was an 04 Cummins and checked mine (cold) and mine was louder. This was the 235 hp version.

If you are asking if I would prefer the Cummins over the Duramax. The answer is NO


However, I wouldn`t mind it if GM offered the Cummins.

I would take a Caterpillar/Allison combo right away.


Now that would be awesome!!! I've driven detroit, cumming, and cat powered trucks...... I love my CAT powered peterbilt!! what a work horse.... with an awesome powerband(course the 18speed makes it all the betterhttp://www.dieselplace.com/forum/smileys/Clap.gif)


cummings make a great motor that can easily be rebuiilt(in frame type) but the d-max just kicks azz!! not to mention the rest of the package is much better than the competition!! interior ergonomics.... are better in the GM then the other guys....http://www.dieselplace.com/forum/smileys/Cool.gif





Caterpillar/Allison sounds good to me too.


Maybe a 3406E YUP YUP got that!!! what a bad azz motor I must say!!Edited by: QuikSSilver

I just took a 04 Duramax for a 24 Hr. test ride with my wife. We both aggree that it is quiter then our 02 Duramax. I just can't see why I would ever want any other engine. As for Dod$e trucks, I owned one and that was one too many. Couldn't keep it out of the shop. If it was the only truck on the market I would build my own before buying another Dod$e. How many of us will actualy keep our pickup for 200,000 or more miles anyway?

I was thinking of a turbocharged DDE 6V-71 mated to the Allison

Test drove a new Cummins, Inside the vehicle was loud and at 65-70 the Cummins produced a harmonic noise vibration, very loud, I would not want to live with a Cummins as my everyday transportation. The Dodge interior environment not on par with Chevy's. On the same note my mom has a Cummins in their motorhome and has been a good engine, of course it is mated to a Allison.


Corsair

Guess I would decide that after a test run hooked to my 8000 lb travel trailer. Thats the way I decided on the Duramax. Find a dealer with Duramax for a demo and they will let you do that. I wouldn't suggest trying that with a brand new truck that hasn't been broken in.

The only real issue with the Duramax is the injectors. We don't know, yet whether the Bosch system on the Cummins will be as sensitive. The LLY makes, what, ten fewer lbs/ft of torque at about the same rpm as the Cummins. So where is the vast superiority over the Duramax? A number of people have said, "if only the D'max were a straight six with that low end torque." The difference between the two in power numbers is less than a sneeze. Is someone going to claim that the Cummins can do more work than its specifications indicate? Are we examining myth or reality here? Sure the Cummins has an enormous crank. It has to, it's so long it would twist a skinny crank like a piece of licorice. Has anybody broken a Duramax crank, yet? Thrown a rod? I'll stick with my D'max. I like its power, I like its smoothness, I like its sound, and I like the dynamic, almost free revving way it behaves. I'm not knocking the Cummins, but I'd choose the Duramax again.

TC

I'll take the CAT/Alison too

Only if they included the best made ear plugs so when I drove around I didn't have to listen to it, oh, and icluded ear plugs for all the cars around me at the stop light so even they can hear their radio.

If I'd wanted a Cummins, I'd have bought a D___e. But I've owned four Dodges since '94, and I'm done with 'em. I'd go Jap before I'd own another one.


It'll be interesting to see what happens with the Dodge/Cummins marriage now that Ford owns Cummins and Daimler/Chrysler owns Dodge. Maybe a M-B diesel?...

Cummins isn't owned by Ford...


My 01 PSD pulled better than my dad's '01 Cummins. I would say that by SOP my LLY will pull better than the PSD did. It sure gets a lot better mileage already.....

If all I did was tow very heavy loads, and you could get an Allison behind it, probably.


But, for what I use it for, pulling every so often and hot rodding http://www.dieselplace.com/forum/smileys/Big Smile.gif, I want a DMax.

My dad worked for GM for 42 years. Kept food on the table and put me through college. I'm buying the brand over what's in it. I've driven all the major diesel brands. I'm happy with my Dmax and would have to drive equally equipt trucks before taking on over the other.

Think I'd stick with the Duramax or the Cat in front of the Allison. Cummins is still too new to the HPCR fuel system. IMHO the Duramax is an awesome engine.

Cummins has been using the HPCR in Europe prior to the Duramax intro into the US ... In addition Europe has better fuel quality ....





Duramax => http://www.dieselplace.com/forum/smileys/Thumbs Up.gif


If I wanted a Potato Chip Truck motor I would have bought one ...





Mac http://www.dieselplace.com/forum/smileys/Geek.gif

ya just cant pollish a terd and dodge is a definitely a terd

NO Dodge, cummins yes. VWTDI in a suped up beetle? Maybe at the right price, got to have a high mpg toy for the kids. CAT instead of 6.5 family of ill attempt at a diesel. But I like my american made japanese designed diesel. Remember the diesel luv? wasn't there a diesel in the s-10? Had a dodge, 1989 with the cummins, awsome motor, 238k on engine, rest of truck was a headache. (nice way of saying POS).

I managed to go into a Dod--e Dealer showroom. Could not get past the loud racket and did not even test drive. Worked several elections collecting ballots at curbside. Lots of diesel pick-ups to listen to. Only one was quiet. Told wife, we're going to go check out the D/A Silverado. The rest is history. I'ts a great ride and I love the new thinking which went into the Dmax.

If it wasn't messy and probably illegal to transport on a plane it would be interesting to take diesel samples when I'm in Europe at the end of the month and see just how good their diesel is.

You could take a sample container with you and mail it back to yourself. If it didn't show up, no big loss.

Lets seehttp://www.dieselplace.com/forum/smileys/Ermm.gif In a word...NOPE!!! For my needs of pullin the RV and other toys, haulin the g'kids around, and driving myself nuts, there is no other combination that I could see myself favoring. Dispite the few discussions of problems on this forum, GM has done a super job building a truck, leading the way to noise conservation, and giving an unbeatable ride.http://www.dieselplace.com/forum/smileys/Clap.gif Thank God the other brands are around to hold prices down cause GM would really cost!! But love the resale over the others. Besides, I like to wear bow ties.http://www.dieselplace.com/forum/smileys/HiHi.gif

Nope


GM is way ahead in technology when it comes to diesel emissions (LLY series). Heck, go to any dodge/cummins based forum and look at all the current owners negative posts on new vehicle (2004) fuel economy. I would venture to say GM will have a leg up on the competition for the next few years, due to emissions regulations which kill the other diesel manufactures.

I would like to get hold of a used CTD for my '79 K20 suburban. I have looked around some, but the prices are pretty hefty. I could go find a 6.2 for less than half the price, stick a turbo on it, and be good to go. If anyone knows a good CTD deal (w/o core), lemme know.


Tim

Cummins in a chev?


Hell yahttp://www.dieselplace.com/forum/smileys/Big Smile.gifhttp://www.dieselplace.com/forum/smileys/Big Smile.gif

I almost bought a 2001 Dodge. Strictly for the Cummins. Had a proven track record. I didn't know about transmissions, at the time. Deal fell through, though. I am nervous about the unproven record of the Duramax. Hasn't seen high milage, yet. I will be keeping my truck for close to ten years. Mine could be as high as 900,000 kms on it(562,500 miles?) Looking after it, the way I do, there HADN'T BETTER BE ANY REASON IT WON'T LAST.
If you want to talk real diesels, my opinion would be MTU, out of Germany.

Germany is where it all started way back when.


I'd go Cummins/Allison combo. The new auto tranny's aren't proven yet and they had some problems with the past autos. I do love my 6 speed though. Edited by: CTD 600

Having had a lot of experience with what I call the Case-Cummins (Cummins designed and built it for Case first I believe), the 6.2-6.5, and now the D/A, I said in March at the top of this thread I'd prefer the D/A providing the injectors hold. Most of you have now read of my disasterous 3500 miles triphttp://dieselplace.com/forum/smileys/Cry.gif with two cracked injectors pumping diesel into the crankcase, with the end result of getting 8 new injectors and a very clean engine interior. And, after all that, I'd still rather have the D/A for all around use. If you could silence the CAT, I'd sell my soul for a Cat/Allison on a GM 3500 chassis in a heartbeat. The Cummins is a fabulous engine, especially for towing, with a tremendous low end pull. But I want mid range power, high range passing powed, the ride of the GM chassis, and the silence of the D/A, not to mention Dodge still needs a transmission. My allison has been well used, nary a problem, and the local Allison/Detroit Diesel shop takes great care of it for me (never would let a GM dealership touch it) with Transynd, deep pan, etc. Guess it is going to take more than 8 injectors to make me leave the D/A.


And let's quit pickin on Hoot! We all know the poor boy has had both hands tied behind his back, his mouth taped, his legs shackled, and his juevos cut off by another entity for speaking his mind. Actually, I looked long and hard for this forum for a while because I missed Hoot and some of you other "riff raff". Your knowledge is great, your help is gratious, your mouths a little caustic, but, hey, this is the US of A, not China. Hoot and the other "riff raff" actually bring a little joy into the world occasionally and break the sterile monotony.

NOT NO....BUT HELL NO


Bout' 10 years ago...give or take.. I had an 84 with the 6.2, not a speed demon, but VERY dependable. I had a friend that had one of those noisy-assed 6B's in a Dodge, and he was forever talking about what a real MULE it was. We were at the beach fishing,and he had a 26' Stamos, he had just bought....went on and on about how good the milage was towing...and what powerhttp://www.dieselplace.com/forum/smileys/Ermm.gif When we all got ready to haul our boats out for the weekend, Jimmy's truck wouldn't pull his boat up the ramp, not wet, mind you, just plain wouldn't pull it out. So they are all standing around scratching their heads, I said I can pull it out. Everyone gets a big laugh....so they dump his boat back in, I hook to his trailer and we load the boat....at this point I really didn't know whether I could pull it out or not....my boat was much lighter....I pulled her in low and eased up.....and out she came....no spinning, no straining....came right on out. Needless to say we didn't have to hear about that dodge NOMORE.My truck had 380,000 when I sold it, and the guy that bought it was glad to get it. Wish I had that 'ole 6.2 back sometimes......nah I still LOVE my DuraMax.....http://www.dieselplace.com/forum/smileys/Wink.gif

Max Owner, there are a lot of trollers going to MTU's. They say they have more power and get better hours per gallon out of them.

Detroit Diesel was taking one of the big V-16 MTU engines and putting different heads and fuel systems on them, and putting them in the Big Haul Trucks used in mining. I just can't remember the series Detroit called it. I have heard that they are slowly going back to the V-16 Cummins, because the Cummins last longer, and is cheaper to maintain.Edited by: BIGMoe

NO! I like the Max, wouldn't trade for that noisy rod knocker.

That's a tough one. I love my D-Max!!!!!!! The only thing that might possibly be better would be same gm pickup with a cummins. I would sure have to give it some thought. The cummins is a really good engine! hmmmmm?????

thanks! as long as we all keep talkin we all keep learninEdited by: hoot

the HPCR pilot injecting system is owned under a joint patent Izuzu/Bosch (gm own 49% of Izuzu) the rights to use the HPCR sytem were sold to Dodge under retricted usage.....They can not produce a engine greater than 6.1L can not have any allison brand and or designed trans, and alot more restriction...to many to list.

If a Cummins was the only diesel offered in a GMC I would buy a Gas engine. I would rather use twice as much fuel than listen to that racket and know I was drivin a half breed.http://www.dieselplace.com/forum/smileys/Approve.gif

Sat in my wifes uncles 04 ctd today and was surprised how quiet it was.Had a nice conversation with the door open and him standing outside.He did say mileage was not as good as his 2000 ctd but with only 1700 miles is to soon to tell.He hauls around a 4000 lb bigfoot camper and the trucks a 1 ton dually with airbags but no swaybar.


Interior was spartan and kind of ugly imho but the white faced gauges look neat.


Just some obsevations.

I would have gone with the Cummins. Track record means a lot, and face it, Cummins has a long track record. Love the Dmax, but we don't know how it will handle the extended miles.
Does anyone remember when they first started talking about making the DMAX with ISUZU technology? I had read in Popular Mechanics or Pop Science that Isuzu has been building Diesels Engines for all sorts of applications longer then just about anyone & their technology in the Injection systems were well above what we were offering here before the DMAX. Also they could get more HP & TQ per Litre.

But explain that one to me. The Cummins doesn't make much racket anymore, and if it was offered you would have a GM truck with a Cummins engine, where now you have a GM truck with an Isuzu engine. So how would it be more of a "half breed?"


OK, I know GM owns part of Isuzu, and they say they "partnered" in the Duramax development (which I don't really believe-- other than just supplying the money)... but that's weak.Edited by: Brake_Torq

Not sure why this is so interesting. If you want a Cummins buy a Dodge. Thus far the D'max is everything it said it was, and more. My money is on D'max to become the engine where some will ask, "if your Ram was offered with a D'max, would you buy it?'" and my response would be NO, the GM truck is IMHO the best built, driving, and riding truck on the market, and besides the Allison is reason enough to go GM, D'max in front of it or not. http://www.dieselplace.com/forum/smileys/Big Smile.gif

http://www.corvetteforum.cc/zeroimg/smilies/nonod.gif


The Duramax already has worked well beyond my expectations.


Every D**ge or F*rd owner I talk to are all envious of the performance capabities of the Duramax and its fuel mileage.


Although the Cummins is a great engine on its own, it would have to have the Allison behind it.

No but the Dodge front suspension is light years ahead of that stupid IFS. the case is alloy so no one will ever make a locker for the front.

A quick note...No but the Dodge front suspension is light years ahead of that stupid IFS. the case is alloy so no one will ever make a locker for the front.

Sorry, guys, I've said this three times already in my short time here--I won't say it again. IF you have a limited slip in the front, then you are way ahead of the rest of the pack as that front diff is OPEN from the factory...I believe.


As to a Cummins in GM truck: Why not? I like choice.


Two co-workers of mine both have 2004 Dodges and their Cummins diesels are very quiet. I would venture to say that I would need a meter to see if my LLY is quieter--the same for the LB7's in the parking lot. I'm not so sure that I would call the new Cummins loud at all. (I have no idea why that would even be an issue if you are hot-rodding any diesel anyway. I guess you just have a "quieter" baseline, if in fact it is, with the Duramax.)


I buy my vehicles loaded and the GM product (LT &amp; all the options &amp; then some) is very nice. I thought my '98 Dodge gasser was also very nice. The only thing that turns me off about Dodge is that rip-off Quad Cab, excuse for a real crew cab. "Four full-size doors," baloney. I'd probably have a "zero" in the complaints department about my LLY/Allison if not for the IFS and the smallish wheel openings. Has anybody ever started a thread on building the PERFECT truck---mixing and matching parts? I think each one has its redeeming qualities and its flaws.


I'm not at all brand loyal either. If I got problems, then the dealer is going to have problems. Anybody who wants my money better make a very good product and provide me with outstanding customer service. I'll even give them second chances and opportunities to make things right. BUT what I will not do is buy things made in Detroit or anywhere in the USA just because it's made by Americans when I can get a better product manufactured elsewhere. Nationalism can be stupid, IMO.


As far as engines go, it would be a tough choice for me personally. Hmmm...Duramax or Cummins....

Being a Newbe on this site I would like to say hello, thanks for the great info and advise, it's good be be here.


I origionally wanted the Cummins but they did not offer a large crew cabb for space, 3/4 or 1 ton single wheel.


I think everyone better see what happens if the fuel system problems are taken care of, the way everyone is treated when they go into the service departments and hear, Sorry!, denail of warranty because our fuel system was not properly designed, and your fuel tank is contaminated, and the repairs are your responsibility. If these issues are not taken seriously, and by their word of workmanship, I will turn my dmax into a cummins, in a split second......


Sorry if my post is taken wrongly, just remember how people are treated after your 40K investment is on the hoist, and after a couple of days playing around, they come out and say DENIAL OF WARRANTY. Your fuel system is contaminated, the repairs are your responsibility. Like you have to fight for what's suppose to work from day one. I also remember a few fella's from previous posts, had expierences with serious engine problems, and how they were treated.


I have 2 very close friends that own cummins. One owns the 2004, and one that owns a 99. They both are in the construction business, and they both beat these trucks to death, I can't believe how these trucks are beaten every day and they have never been down!. One thing is for sure, they have never needed any issues with injectors, or fuel system contamination and so on, the one guy with the 99' is still pulling his 30' 5'er, went to Black hills last month, his milage is 175,000 plus, and still has stock injectors, only some tranny repairs ( due to existing tranny probs for years ) but solid engine design to last many years. GM better wake-up, or maybe we all better wake-up and see who's cheating who..........Thanks for your support.....http://www.dieselplace.com/forum/smileys/Confused.gifEdited by: Bigwheel

I doubt I would, I hate the sound of that engine. I'd rebuild and turbo my 6.2 first !

Ford is on the right track...

Above is a topic concerning the 6.0L and future hopes for Ford.

I read or heard (here we go) that the 6.0 problems lie with Ford. Navistar built the engine, but Ford added their own electronics to the engine. I think (haven't read much on the 6.0) its electronic controlled problems the Ford is having.
Of course someone has to be blamed, and Ford is blaming Navistar. Navistar built the 7.3. Once the turbo was added, the evolution of the 7.3 was complete.
My thoughts.
