anyone know anything of substance about diesels?

[Yaj Yak]

any first hand info would be greatly appreciated...

Right now I am kinda hunkering down on 02,03 7.3 powerstrokes, along with 02-04.5 duramaxes... and 04.5-06 duramaxes...

stuff i kinda think i know so far...

02-03 powerstrokes are kinda unstoppable... but transmissions will go out... not if- but when...

02-04.5 duramaxes- get super good fuel economy (20+ normally), are quite quick for what they are out of the box (stock), but have injectors inside their valve covers which enjoy going out... and the injectors them selves normally go for at least 1k+... that scares me...

04.5-06 duramaxes- prolly the least amount of fuel economy... not as quick as the powerstroke or older duramax... not as many mods... but dont have the injector problem... has a variable vane turbo, as well as a cold idle computer function which makes the truck run at a higher rpm when cold out... (seems to be a pretty cool thing on the duramax forums...) also... allison transmission is badass...

basically. i want the ride of a newer gmc, wiith the potential of an older gmc, with the reliability of the powerstroke, the fuel economy of an early duramax, and the looks of a ford... someone molest that into a truck for me.


and yeah... dodge has cummins, and those are badass, but I will not be caught dead in a dodge. so dont go there


so is there anything to contribute in my search?

02-03 Strokes have been out for quite some time now, I'm sure transmissions really aren't 'that bad' as far as cost goes, and I'm sure you can get a 'built' tranny for cheaper than you could for a newer Dirtymax.

I've been in my buds 05 Dirtymax, and she's a beast, but still got 20-21mpg on the freeway when he wasn't whomping on it, Plummeted to 14.5 with the chip and whomping on it.

from what i have seen, most diesels do better mpg wise with a tune... weird...

Depends, he was using an edge, which has 3 modes, 2 for power, one for econ, the power ones demolished fuel, he never bothered with the econ on, Lol.

gm interior though...that would be a sick truck

pffft cummins12 or 24v/NV4500/atlas swapped in a 67-72 bumpside highboy or a 79 K30 3+3

I don't have any first-hand experience, but last year we bought these guys, http://www.pickuptrucks.com/index.html. The site's creator, Mike Levine, has been writing about trucks for 15 years and there's lots of testing and technical info about all the diesels over there.

Like this shootout from 2003 of diesels: http://www.pickuptrucks.com/html/stories/2003shootout/page1.html

Diesel's need routine maintenance far more than that of a car/regular truck. Fuel filters and injectors are very easily clogged.

Oil changes are more expensive.

with gm's ride quality.. fuck yeah.

im not sure where your firsst lnk was supposed to take me.

but they get better gas mileage and are more reliable... and what kind of experience are you talking from about the injectors being very easily clogged

First link was for the pickuptrucks homepage, the second was to their diesel shootout.

hahahah. i first thought you meant your family or something bought some truck... went to the site and was like... uh there are many trucks here...


now i realize your company bought that website.

Swap in the cummins, and get a modified bellhousing to fit the cummins to the allison trans.

 

[Yaj Yak]

yeah cuz that is monetarily feasible.

7.3 FTW. BTW the oil change interval is at least 5k miles but many places that change oil dont know that.

Fuel filters are 30k. I am not a Ford guy but i would by one with a 7.3 in it.

Also, if those are Bosch injectors you are talking about in the Chevy they have made improvements on those IIRC but they are probably exhausting old stock too.

One more thing. On common rail fuel injectors stay away from Biodiesels! B20 the highest but Bio diesel will shorten the life of the fuel system b/c of contaminents getting through the fuel filter that were built up in the fuel tanks. ULSFD takes lubricity out of the fuel so feel free to add some oil to the fuel tank for preventive maintenance but definately after an injector swap (the oil in the fuel helps the injector break in.)

that is much appreciated information, and myself, like you, I am not a Ford guy, but I would most definitely buy one with a 7.3 in it.

if it were me, i would go for the silverado duramax. I've worked on a lot of powerstrokes and a lot of duramax's, and i feel that there is no comparison in ride quality. the duramax is so much smoother, the allison shifts like butter, and even lifted it rides like a cadillac. the ford just feels too much like a work truck.

 

[EmersonHart13]

I have heard so many good things about the Allison trans that I would pick that and the Duramax because I haven't heard anything that bad about the newer Duramax. Well I guess other than the decreased modability but that isn't that much of a negative because I am sure it will continue to grow.

 

[Angus]

They are big.

that substance enough?







but on topic, I hope you get one, they are bad-assery

im so nervous about the injector bs tho..

you'll probably end up upgrading them anyway lol. and btw the duramax also sounds sick with a 5in exhaust.. just saying
