Nozzles, go with F1 Diesel, the flux injectors.  Those Flux injectors are the best on the market.  They can give you INSANE power and they run cooler than anything that is on the market.  The closest would be the DDP injectors but they run very hot compared to the flux and they dont give as much power.  Also, You're already running the bully dog triple dog, if you get these injectors.  Your EGT's will be high unless you have a after market turbo to shovel more air in there.  Water Methanol would even be a good upgrade too.  Just PM me and tell me where you're wanting to go with your truck and we will discuss.  Or I will give you my number or whatever I don't care.

Trust me, if you want nozzles, flux are the ones to go with.  Richard Brown, John Isaac, they all agree Flux are the best on the market.  I have talked to them Rich on the phone daily and John Isaac in person and they say the blow away the competition.

Take this for example.  Richard Brown of Browns Diesel tested out the flux 2.5 with a Aurora 5000, a modular tuner, and a 250 shot of nitrous and drop 893HP TO THE GROUND MY FRIEND!!!!!  Thats crazy!!!!!  And if I am not mistaking, I believe it was the 03 to 04.5 truck.  

03 5.9 send me a PM and I will give you his number, but I really need to know if you're interested  

Yea jms_shepherd i guess the real test would be to pull the trucks and see what has worked on either end. That is if u r up for a friendly competition. Were r u located at. I might have to make a trip and see what r trucks have. How many miles do u have on ur truck. let me guess like 50,000 or so. How is almost 200,000 on a truck that is only 5 years old. Do the math. Thats like 38,000 miles a year. That is a lot of miles on truck that has been runnin all stock internals and that with stacked chips, turbo, injectors and more. I know there r trucks with more miles on them than mine. But i guess whatever u guys want to do with ur trucks is up to u. Later.  

I guess you haven't realized that I dropped that conversation a long time ago.  Good job at showing your stupidity.  And who in the world challenges someone to a race or a pull over the internet, thats the most ridiculous thing I have ever heard.  

what r u talking about. Its a friendly competition since i am going to be travilin and pullin my truck all over next year. So i was wondering if i was in ur area that u wouldn't puss out. I am not calling u out. Im not telling u that u have to do this on this day and time and all that.  

U need to calm down on that end. U r takin this way to seriousely. I don't mean to make u loose sleep over this. I mean u have all that work done and u have to use it sometime besides u just saying u have it done.  

Anytime you push more fuel with an injector or injector tip upgrade (above 50hp) you need to really look hard at your rail pressure.  Since you're wanting stage 3's then you're going to need to look hard at your entire fuel system.  Your stock lift pump isn't going to supply your stock CP3 with enough fuel, so a FASS 150/150 and a modified CP3 will be tops on your list after you swap your injectors.

More air will be next and since you've got a 5 inch exhaust you're already good there.  A new intake manifold should be included, either the BD or CFM+ intakes are great choices.  Since you're running an '03 your boost pressure is going to be around 22-23 psi.  A boost fooler/boost elbow will get you up close to 30-32 psi and you won't need to ring the heads or use studs on the head.  Anything close to 40 psi or more and then you're going to need to do some top end work to your engine so you won't lift the head off the block.

You didn't say if you had the standard output or high output 5.9 in your '03.  Check the engine tag on the drivers side of the engine near the CP3 since both were offered that year (250 for the SO, 305 for the HO).  Ideally you'll want the 305 HO since there is more in the way of engine lubrication, but if you keep and eye on your oil you'll be fine.

Bluetech's recommendation of a TC and VB are both good calls.  The 03's are the first of the 3rd generation and the tranny is solid until 400hp, but the torque converters in them suck.  I would look at ATS for the tranny work due to them being experts in that area.

Have fun modding your rig.



Kris  

Yeah i've gotten up to 29 psi without my boost elbow on. Mine isn't the HO though I really wish it was. I haven't heard very many good things about ATS so i was thinkin about goerend or Suncoast. Thanks for the info  

If you plan on doin that much fuel mods on your truck I would highly advise getting a Dual Feed line from Industrial Injection then your fuel rail will never be short on fuel I found that out the hard way with my 05 I only had the triple dog on it and the rail lost pressure and my number 6 cylinder went dry long story short I had to pay for a new 15,000 dollar engine thats my 2 cents  

Marine, I totally agree with you and thanks for completely proving my point on this thread unlike some people I know who commented on this.  It's good to see that there are some people here that know what they are talking about i.e you, cummins 04, and myself.  

He is right though, with all those fuel mods you're gonna need more air, if not you're gonna burn up the motor simply because it's gonna be SO RICH in fuel.  A CFM is what I would personally go with, they don't dry as much head simply because they are made of a very hard plastic, I could run my truck for 80 miles and park it, pop the hood and place my hand on that manifold so that tells ya how it doesn't draw heat.  Boost builders are also a definite upgrade, and they're cheap and can give you around 50hp depending on you're upgrades.  After that, the only other thing I could think of would be an intercooler, however they're pretty efficient on the dodges, at least the 07's are, you're might be different, but if it is.  Banks has a good system.  It has 3 inch tubing and it comes with a manifold plennum, it's also 1200 for the whole package.  Which is cheaper than anything on the market.  But it will give you more air and signifigantly drop your EGT's anywhere between 100-250 degrees, depending on setup.  Once you have that taken care of, you would either have to look at a turbo, for more air, or a compound, which once you get an after market turbo, with you being over 40psi, you're gonna need studs, once you get studs, you'll be good for awhile.  Those Cummins are BOMBPROOF at the bottom end. Once you have those upgrades you're next thing will be keeping things cool, whichI am sure everyone will be interested in discussing that in this thread as well.

Goerend has pretty solid transmission, Richard Brown of Browns diesel is putting over 1200 to the ground with those things and they are holding up GREAT he says.  They are solid, and they're customer service is incredible, and they warranty their stuff too.  

hey jms i know of a couple of people that have challenged guys on here to a race and have become good friends afterward. my question is what do you do with your truck? and also how much to it cost to have all that done?  

also jms dont be so uptight and crap, i didnt know we had to so proper on here.  

Yeah he will need a lot more air.  I used an AEM Brute Force HD intake and CFM+ manifold on my '03 before I traded it in on my '08 and it made a huge difference in mileage (12.5 MPG to 17.5) even without the fooler and elbow so I knew I was moving more air.  The stock intercooler should be fine up to around 500hp, but hey, we all like a little bling under the hood and the Banks unit (the only thing I would buy from them) will look really sharp both under the hood and through the front grill.

Other than that he'll be fine ... until the next mod (heheheheheh).



Kris  

I know im gonna need more air so i've been looking at the CFM manifolds for a while and will probably put that on the same time i put the injectors in. I will eventually put in the charged air cooler and other things to help cool but i'll need money first and yes there are many more mods to come.  

I use my truck and race it on the weekends most of the time.  But even then I don't do that to much.  I am waiting for the strip before I do anything to serious.  Definitely will not pull anything simply because thats not what I bought it for, I want a 8500lb truck that can beat souped up mustangs camaros and vettes.  Thats why I bought it.  

I think CFM would be wise.  But be careful about putting those injectors on with that bully dog triple dog, and DO NOT run the crazy larry with those injectors.  If anything turn the tune down a little and run the injectors.  You WILL burn something up and that will be VERY bad.  That CFM will will give you more air and drop EGT's but not as much as a turbo, or intercooler (which we have talked about and you don't need a new intercooler yet).  I would personally upgrade the CP3 first, this will restore your alrady lost pressure, then do the turbo you're already running a lot of fuel with that bully dog so buy the turbo to balance the fuel to air ration, then do injectors if you did injectors before the turbo you would be wasting even more power hence a huge cloud of black smoke so thick that it would flood your downtown.   Once you get those things, the turbo will help keep things cooler, but then we can hit even more areas to work on cooling such as water meth, then the intercooler, and for the extreme NITROUS!!!  But make sure that is staged and staged right!

You're going at it the right way 03 5.9 so don't worry.  

John  

Speaking of water-meth and nitrous, when you buy the CFM+ make sure you get the model thats already been drilled and tapped for injectors.  This will save you time and money down the road as you'll be ready for it and not need to buy another intake manifold.

Snow Performance's water-meth setup has had nothing but fantastic reviews and will give you some extra power and lower your EGT's even more with what you're looking to do.
