2003-2007 5.9L  DROP-IN CUMMINS TURBO:

After the extensive testing we did in the Cummins Turbo Shootout back in 2013 we learned a few things about Cummins single turbo systems.  This test featured 5 turbo's, recomended by the manufacturer, analyzed and compared side-by-side.

If you read the article featured in Diesel Power Magazine or listened to the episodes we did at the Diesel Performance Podcast then you already know there was no clear 1 winner.  The reality of aftermarket turbo's is you have to sacrafice something to gain something.  So we set out to develop a turbo that could meet our requirements for being a great daily driver, good for managing EGT's while towing and something we could cause havok on the streets with.  

Cummins Stealth 64:

  • Great Daily Driver
  • Good for managing EGT's while towing
  • Cause havok on the streets!

Duramax VVT Upgrades:

 

The 2004.5-2005 LLY was the first model Duramax to be equipped with a Variable Vane Turbo (VVT).  VVT  technology provides quicker spool-up, better EGT control, and better overall boost control.  This is also commonly referred to as a VGT or Variable Geometry Turbo. 

To understand the basics of a VVT or VGT technology take a look at this VIDEO on YouTube.

The stock Duramax VVT turbo from 2004.5 until 2010 is similar.  Slight changes to each model (LLY, LBZ and LMM) were made in compressor size, aspect ratio, blade profile and other features.  Despite these changes, you will find the same peak power potential of approximately 530 RWHP.  As a Duramax performance enthusiast this is probably just not enough power to keep your interest for long. 

There are many upgrade options on the market.  Deciding which one is the best for you can be tough.  An endless amount of forum threads and user stories makes it challenging to decipher fact from opinion.

'85 Square Body fitted on a 640HP Duramax

Scottsdale Duramax

This 1985 Scottsdale pickup truck started life with a 6.2L diesel motor.  That's right, the non-turbo, under-powered, over weight regular cab had a dismal 130 horse power from the factory.  

We love the body lines and nostalgia of these trucks.  The swap being partially done prior to it coming to us DuramaxTuner.com was an appealing feature to this build.  This provided a solid head start on a project truck we intended to use for testing.

LB7 Duramax Turbo Upgrade!

IF YOU ARE LOOKING TO UPGRADE THE TURBO ON YOUR LB7 DURAMAX THERE ARE A FEW THINGS YOU SHOULD CONSIDER FIRST

  • What is your power goal?
  • How do you use the truck?
  • Is there a sled pull class you would like to compete in?
  • What are your future plans for the truck?
  • Are your mechanical skills up to par for installing it yourself or are you taking it to a shop for installation?
  • What is your budget?
With so many options on the market, it's very hard to determine which is the best choice for you.  Of course you can always call each manufacturer and discuss what options they have, however you will still need to ask the right questions. I hope to save you time, money, and the headache of weeding through all of the hype out there and point you in the right direction in  how to select the right turbo for you!


What are your Power Goals?

Clearly defining your power goals will help you establish a game plan. No one wants to buy a turbo that will not work with their future goals for the truck. However there are some baselines that you need to set first; like are you going to build the motor?  On an LB7 we know the rods cannot handle more than 650HP.   So if you're not going to invest $15k-$25k on a motor build, there's no point in purchasing a turbo that is 800 HP capable.  On the flip side, if you are going to do a motor build in the future but want something more suited for the stock truck, consider a valley charger that will still work-in a twin kit.  This is a great way to maximize your dollar-per-horse-power. Below you will find a list of just a few chargers and their peak horse power.

6 Turbo Chargers + 1 Month of Testing = Cummins Turbo Shootout

 

 

If you ask five different diesel shops which single turbo upgrade is best, there is a good chance you will get 4-5 different answers.  To separate fact from fiction, we put together a rigorous test for five of the industry‚Äôs top turbo chargers.  Also included was the factory HE351 to see if the usual reported improvements over stock are true.  You might be wondering,  How did they choose the turbo chargers? What tests were run? And most importantly, What were the results?

The Cleanest and Meanest LB7 Dually I Ever Drove

[fa icon="calendar'] Sep 12, 2016 11:06:32 AM / by Paul Wilson posted in Stealth 64, LB7, Stealth

This LB7 Dually Killing It

I had a customer come into the shop with a pair of up-pipes and a down-pipe he wanted installed on his LB7 dually.  I told him that it would not be a problem and to come by the shop early one morning.  I happened to be near the front door when the the truck pulled in and my jaw about dropped when this thing came barreling down the road and whipped into the parking lot.  

After a brief discussion with the truck owner I found out this unit had just 89k miles on it and everything was original.  This gun metal gray paint had no fading or scratches and free of any noticeable chips or short comings.  The interior had no cracks in the plastics, the charcoal gray interior was mint, even the white paint on each button could still be seen clearly.  I think what really set it off was the 22.5" semi tires wrapped with 37" rubber.  Other basics had been done as well, all the trim was tastefully done, headlights and head unit upgraded and so on.  Looking back, each individual piece was fairly standard and readily available.  However, when put together on this 4 door dually; it just worked perfect!  

 

 

After our previous conversation of the truck, I found myself getting as excited about the potential for how cool this thing could be.  However, as any truck build story goes we ran into a few small hurdles that we needed solutions for.   Bolts broke while removing the up-pipes and the turbo had to come out.  It left us with an opportunity to replace the stock IHI with our Stealth 64 LB7 turbo.  Now we knew that because of how the owner used his truck that the transmission was going to need attention down the road . . . . shortly down the road.  It ended up being very shortly down the road.  Once the truck had a  DT750 built transmission we decided to install a few supporting mods.

After the truck returned to it's daily life as a highway driver/midnight tollway race truck, it was not too long until we had another obstacle to overcome....
