Default My first diesel*Need direction!*

So here's the story. I've always been into fast cars, anything with a turbocharger, supercharger or pretty much LS1 has attracted me. However, now I needed a work truck and I bought a cummins. I need some directions on making this thing a beast.

My truck is:
2002 Dodge Ram 2500
24v Cummins
Automatic.
125,000 miles.

I'm looking to go FAST.

I realize there are a few things I should look out for, one being the lift pump failure.

Therefore I was thinking about starting my modifications with:
Airdog 150
Waste gate hook
Some sort of chip
Turbo back exhaust

What do you guys think?

My diesels in pretty solid mechanical shape but I definitely want to go farther than just those things.

I want to build my transmission to hold a huge amount of torque(I'm want it to be reliable to around 1200 ft/lbs at the wheels when this projects all said and done) but I have no idea where I should go to get mine done.

Also, I'm looking to go with a bigger turbo like this Diesel Dawgs Performance

Bigger injectors, an intake manifold and then an exhaust manifold.

Do you guys recommend anything else? What kind of power should I expect with all that on just diesel?

Can't go wrong there
Waste gate hook
Someone with 24 valve experience can guide you on that
Some sort of chip
yeah
Turbo back exhaust
definately
You also need to get the intake side breathing better. Either the BHAF (do a search and you'll find it) or a cold air intake

What do you guys think?

Most people go with ATS, Suncoast, or Goerend, lots of topics on here, just start crawling around

If your talking BIG numbers, then yeah you'll need injectors. The intake gains are marginal until you get ALOT of air, and usually people do their exhaust manifold when they switch turbos or go to compounds

Welcome to the site. Just start crawling around and you'll find more than you ever needed to know.

Sounds like you have a pertty good idea of where to start. Its a really good idea to start with a new LP, fass or airdog along with a fuel pressure gauge. I wouldn't worry about a waste gate hook if your planning on going with a larger turbo. As for a chip i would recomend a quazilla adrenaline or a edge juice with attitude. And as for the exhaust, combine it with a BHAF and you'll be off to a good start.

Thank you guys so far.

Yes I do have big plans for this truck. It seems fairly simple and more fool proof than a gasoline motor.

I want big power, to start off I'm purchasing:
5" turbo back exhaust
Quadzilla adrenaline
Airdog 150

Then later down the road I will get my transmission done(I'm going to research this now)

Then I'm going for a super B turbo, with injectors and atleast an exhaust manifold.

Well, you'll burn up that trans in a week with an Adrenaline... Talk to either Dave Goerend, or anybody at ATS, HTS, NADP, or Suncoast, they can get your trans working like it should, but keep in mind its gonna run you between 3-5 thousand to build it like you're gonna need it.

As far as a Turbo, try something like a 64/12 or 64/14. A Super B is gonna be too small for what you want. Unless you really want extra drone and noise, stick with a 4" exhaust.

Once you start with bigger injectors, and a bigger turbo, plan on O-Rings for the head, along with a set of head studs.

Its a viscous cycle. Once you upgrade one thing, another becomes too weak, upgrade that, and something else needs more...

The j-hook works to make the stock hy turbo build more boost but be careful as the hy has the small exhaust housing and gets warm pretty quick but will work. I would say for a programmer get an edge drag comp and some gauges. The monitors are off and a good set of mechanical gauges will be a lot better. I would stay away from ats and go with any of the others mentioned. For injectors spend the extra money and get a good set of high quality injectors they run better and just flat work better. But for the kind of torque you want make sure you get enough turbo. Your going to need 600+ to the rear wheels to get there. But that super b will work good for a top turbo over a s400 and then a set of 240hp sticks and you should get there

If you really wanna make power, just sell the 24V and buy a 12V. Getting gobs of power from those is easy, .

Thank you for the input guys!

I think I will stay 4" I guess, exhausts are dirty cheap for trucks.

I'm looking to have the transmission built for around $4000, and to hold 1200 ft/lbs.

However my power goals are BELOW 1200 ft/lbs.

I was thinking about going with that Super B turbocharger, and a set of 200 sticks. Once the head gasket goes I will go with an oring-ed gasket and head studs.

What do you guys think about that?

I want to stay single turbo for simplicities sake.

You'll need at least a Super B Special to cool 200HP sticks. Personally, I'd be looking hard at a Silver Bullet at that point.

You should be able to get a pretty beefy trans for $4000, but make sure you get good clutches and steels. If you have to go without a billet shaft to meet cost requirements, skip the billet output. If the output breaks all you have to do is pull the t-case, etc... You won't have to pull the whole trans.

IMO its easier to switch an input than an output, but the damage caused by a broken input can be far greater. As far as getting a bullet proof trans for 4000 that will hold that much power, the only way I can see doing that is building it yourself. Honestly, the parts alone for a trans that will take that kind of power and any punishment are going to run you about 3700-4500 dollars depending on what you get. If you buy a built one, it will probably run you close to 6000 or 7000.

Do you tow at all with this truck? If so, how much? Are you willing to throw nitrous or drugs at it? I would recommend a 64mm turbo if you're going to run a single, or a set of twins. Twins are a lot of fun man, and aren't always as expensive as you might think. Sounds like you're off to a really good start though, and going about it the right way. Making a plan first and then going from there instead of buying parts and throwing them at it.
