Common rail advice
 

I'm lookin into gettin a newer truck and decidin between a 6.7 and a common rail.
Is there any emission regulation crap in common rails or no? If so what are they and can they be torn off. And also what would be best mods to get besides intake and lift pump? I'm not too familiar with common rails so figured I'd ask around before gettin one.
Thanks for any advice,

All dodge cummins motors from 03 to now have the common rail. It is refering to the fuel rail on the motor. The fuel rail can't be removed.And there is no emmisions tied in with the fuel rail.
As for mods, you can do the same mods as the older motors,air filter,air intake,exhaust,and fuel system upgrades.

I wasn't sure if 03-07 had egr coolers or not and any specific mods to start off with for a 5.9 cr

03-06 I believe are non emissions motors. No dpf, no egr or that crap. Check for blow by,check fluids see how they look,smell etc.

No egr or egr coolers. (thats a good thing) To start off your mods, go with exhaust mods, then intake (CAI kit) then better flowing intake elbow/manifold. Its important to free up the exhaust and intake to make it breathe better. Then your choice of programmers(most popular is Smarty/ smarty jr.) If Auto, think about trans mods (will be weak link at this point). It manual trans, clutch will be weak point.

Actually I believe the 04.5+ have an internal egr.. via cam shaft. It opens the exhaust vavles to a certain depth so not all the exhaust exits which in return double burns... Kind of like the acert cats... The twin turbo setup it gradually reburns the exhaust.. and it has a cat under it.. but new exhaust can fix that... The internal egr you'll have to get a new cam... But other then that no external egr, or any other bs that doesnt need to be on there

Good info to know bro.................

Anytime bro.......................

Don't forget gauges before big mods to. Especially rail pressure and lp

Get an 06/07 5.9.

Get an Edge CTS Insight for gauges.

Get Efi Live for tuning.

Call it a day.

No non of the 5.9L have any kind of egr unless they are california compliant. The 6.7L use a common rail fuel system also. Its just a bigger engine, and they do have an EGR system on them which takes exhaust routes it thru a cooler and back into the intake which is "Fine and Dandy for your engine"-EPA. Acerts have a ARD system which they use to burn the shit out of the DPF filters. They always seem to fail during regens.

The way a common rail works,
Is you need good clean fuel, which is pumped to a High pressure fuel pump, that pump sends fuel to a single rail.(All six injector lines are feed from the same rail.) That rail which is feed by the high pressure fuel pump generates up to 30,000 PSI of fuel pressure and unlike old mechanical injection pumps in the older cummins. The injectors are fired by a 120 volt electrical system which is set off by the ecm. The common rail systems utilize a double pulse injection which is why they run so quite. The dampen the knock made by diesels. Ford, Dodge and Chevy now all use Common Rail Fuel systems. So their is your common rail fundamentals. as for the big rig industry Cummins finally came out with the Cummins ISL which is a common rail no more ISX!!!! YAY...

i don't know,they are changing the big rig cummins motors quite a bit lately.
I really hate the honken large fuel filter on the newer cummins.
I don't know what the designers are smoken when they design the motors:argh:

Alrighty thanks guys no sure what ill get yet I've ruled out 6.7 but not sure if ill stick with a 24 valve or common rail 5.9

Ill take the big ass fuel filter(Even though I cant put it back in without spilling diesel on me) over them trying to beat mecedes benz in making the MOST complicated fuel system.. Im still not 100% sure how ISX works lol. But they sound like they are always missing lol.

Nuthin will ever beat Mercedes or paccar on the most complicated motors ever!

I've got an 07 if you're interested
 

2007 Dodge Ram 2500 MegaCab
With a 5.9L Cummins
118,000 miles

Interior-
- Custom two tone, light and dark grey leather interior (brand new!)
- SoundStream in dash dvd/mp3/bluetooth/cd player with navigation and 7 speaker infinity system with 2 10” Kicker CVR subwoofers and Rockford Fosgate R1200-1d.
- Steering column mounted Cobalt boost (0 to 100psi) and fuel rail pressure gauge. (Remaining gauges through Edge Monitor, Up to 8 on monitor including EGT, Transmission gear select and Lock up, corrected MPH, Engine Coolant Temp... ect)

Engine-
-Edge CTS Juice with Attitude (hot unlocked rarely used)
-flex-a-lite fans (stock still available if requested)
-AirDog 150 (filters changed every 5,000 miles current have 1200 miles on them)
-Industrial Injection CP3 33% over (also have stock CP3 76,000 miles when removed and a remanufactured CP3 with Industrial Injection's bag of parts (10,000 miles on it)
-JUST INCASE YOU MISSED THAT … 3 WORKING CP3'S (dual CP3 kit already sold).
-Fuel rail race plug
-125 HP injectors, checked, and assembled by Industrial Injection
-Industrial Injection Silver 64 turbo (50 PSI waste gate)
-ARP 625 Head studs
-custom built transmission rated to over 800+ horsepower (redline clutches, kolene steels, carbon fiber 1 piece 2nd gear band, sonnax billet 2nd gear Super Servo Assembly, billet band strut and anchor, billet input and intermediate shafts. 130 psi gov solenoid, stage 3 shift kit, triple disk converter, output shaft is stock because it is easiest to change, build as the weak point on purpose, $800 opposed to $6,000+ you do the math.
-BD intercooler
-Industrial Injection performance cam
-MBRP 5" downpipe back exhaust
-I've only run full synthetic Schaeffers engine and transmission oil since purchase (engine oil and filter every 8,000 miles, transmission only has 26,000 since full rebuild (transmission fluids changed twice)

I'm sure I'm missing a few odds and ends so ask any questions you have.
I really hate to sell it and the only thing worse than seeing it go, is seeing it go to a dealer to be shipped off to someone that won't appreciate it. If there was any way I could manage to keep and use it I would in an instant! So here is the remainder of my plans for her.

My next steps were EFI live tuning, Snow performance stage 3, valve springs, either an 86mm(big brother) or 91mm turbo, larger dual CP3 set up, and an ATS 5 star torque converter.
No one would ever expect it to have so much go in such a big package and there wouldn't be much, if anything, street legal that could touch her.

[QUOTE=minncountryboy;1007754]Actually I believe the 04.5+ have an internal egr.. via cam shaft. It opens the exhaust vavles to a certain depth so not all the exhaust exits which in return double burns...

I meant to explain this, most engines perform what is called Valve Overlap (AKA Scavenging). Where the intake and exhaust valves are both open so the cool intake air can draw out the exhaust and help cool the exhaust valve.

[quote=RanchhandTCR;1008639]Ahh I was just always told it has internal egr and three injection events and to change these you gotta put in a new cam.. which in return will give a decent amount of power gains...

I'm not really sure why no one has mentioned a transmission.... You're going to need to upgrade your transmission pretty early on unless you don't mind dealing with the loss of power and fuel economy a slipping tranny causes. 47 and 48re especially (5.9 transmissions)..

Well he asked about the common rail not the transmission, but in any case, I think they are a perfectly good tranny. People are just uneducated about maintaince of them. When you have your fluid changes along with the filter you must adjust the bands. Mine has 249K and no issues besides a loose ground of the pcm.

touche.. you are absolutely right!
This is a common rail post and I know not everyone grabs some power adders right out of the box.

These transmissions are perfectly suited for the power they came from the factory with and the factory recommended tow rating. With regular fluid and filter exchange these units will last as long as the engine a million + miles.

it's the power adders that kill them and it doesn't take much to start eating them up. So no matter what common rail you choose wether it be the 5.9 or 6.7 keep them relatively stock and you'll have a power train that will last.

The 5.9 03-07.5 do not have an egr system but the 6.7 does. You can delete the EGR through 2012 with some parts and tuning as long as you aren't in CA. I've heard a rumor that you will not be able to do the delete at all on the 2013/14 6.7 and they will be running DEF (diesel exhaust fluid)... supposedly you'll get a bit more power and fuel economy.

Crazyrocks you are right but if you dont plan on doing high horsepower mods they will be ok.

Now as for delete kits for the def systems, the def system is used so the DPF can get a lil bit of a break from filling up with soot, and help with fuel mileage, but all these emissions crap it just as bad for the engine as dumping sand into the intake. Since EPA just hammerd all the companies out there that make delete kits were all kinda screwed. The gov is taking all the fun stuff away or Diesels and Guns. Just stick with the good ole 5.9 cummins.

Amen to that. Ya cant really go wrong with the good 'ol 5.9. :yeah:

I hear you there. But i don't put fuel in the filter when i put the new ones on. I just turn the key on 5 or 6 times and have the lift pump fill up both filters and push out the air then start the truck. Always works for me.And i also agree on the miss with the cummins,lol
Now on the older cummins, i do put fuel in the filters.
