Add-a-Turbo Kit for 6.7L Cummins | Dodge Towing Compound Turbos

Fits 2007.5–2018 Dodge 6.7L Cummins

*Retains EGR and Exhaust Brake if desired*

The Diesel Power Source Add-a-Turbo Kit is the ideal towing twin turbo upgrade for 6.7L Cummins owners from 2007.5–2018. Designed to work with your factory HE351VE turbocharger, this kit adds an S475 for serious gains in torque, EGT control, and horsepower—all while maintaining exhaust brake functionality.

Key Performance Benefits:

  • Spools like stock while significantly improving airflow (up to 2.5x)
  • Reduces EGTs by 250–400°F
  • Retains stock turbo and exhaust brake
  • Horsepower increase: 23% | Torque increase: 24%
  • Supports up to 650 HP (700 HP with S480 upgrade)
  • Improves mileage by up to +1 MPG

Why Choose DPS Add-a-Turbo?

  • Direct bolt-on installation – no fabrication required
  • Stainless steel TIG-welded exhaust tubing
  • OEM look – retains factory air box
  • High-flow air filter and 2-piece 4” downpipe included
  • Uses stock HE351VE turbo as high-pressure stage
  • Upgradable to S480 turbo (for builds up to 700 HP)

Included in the Kit:

  • S475 Borg Warner turbo (75mm compressor / 96mm turbine / 1.32 A/R)
  • Air filter & intake tubing
  • Hot pipe and low-pressure charge pipe
  • 2-piece downpipe
  • Stainless exhaust tubing
  • Support bracket for S400 turbo
  • Steel braided high-temp oil supply lines
  • Water line, flex oil drain line, and fittings
  • Gaskets, clamps, bolts, nuts, and hardware
  • Heat shield and heat wrap
  • Coolant tank (select models)
  • Complete installation instructions

How It Works:

  • Dual compressors work together in their most efficient ranges, creating cooler, denser boost air
  • Boost pressure and exhaust drive pressure approach a 1:1 ratio
  • Improves combustion and reduces in-cylinder heat
  • Additional air molecules act as heat sinks—similar to jet engine thermodynamics

Technical Notes:

  • Kit is capable of over 70 PSI boost
  • Head studs recommended for 45+ PSI; fire rings recommended for 55+ PSI
  • EGR and DPF systems can remain physically intact, but most trucks will require prior emissions delete and tuning
  • Diesel Power Source does not sell or support emissions delete components

With a 500 HP build, you can expect an additional 120–125 HP. Designed for power, towing performance, and street-friendly drivability, this Add-a-Turbo kit is the cleanest, most OEM-like compound upgrade for your 6.7 Cummins.

    Great choice for an aftermarket turbo, or even compounds! My DPS add on turbo kit is amazing, completely changed the truck, from EGTs, to spool and psi. Completely recommend yall!

    Not that Larry Bird. Your Add A Turbo Kit for my 2012 made a huge improvement on towing with my truck. Great power and helped with my EGT temps. Once the stock turbo goes out I plan to upgrade with the Turbonator. Thanks for making a great fitting kit

    I bought this add a turbo kit for my 2005 Cummins and what a difference it made towing. I live in the west and travel some good mountain passes with a travel trailer. No issues with the EGTs and no down shifting. I already want to replace my stock turbo for their Turbonator turbo. Great kit! and everything came in it to install.

    I don't normally comment on my truck part purchases, but I felt the quality of your kit was worth taking the time for. I recently purchased one of your stocker / S475 kits for my 06 ram. I have to say I am very impressed with the quality and packaging you guys do. This is my first compound turbo set up. I looked at many kits before purchasing yours. I looked at cheaper and more expensive. I had nearly talked myself into buying a cheaper kit. After receiving your kit I was immediately satisfied with spending the extra money on it. I opened the kit and was very impressed with the packaging alone. I thought to myself, if it performs half as well as it's packaged, I was going to be very happy. I had one issue after installation, but it turned out to be my fault for assuming. I assumed the tube from the output of the S475 to the input of my stock turbo was molded to the connector that uses V band clamp onto the S475. I had one extra clamp once installed and I thought it was odd, however I took the truck for it's test ride and was very impressed with the faster spool up but the system got very loud and not as much boost as I had anticipated. I found out very quickly where the extra clamp went. After that mistake was remedied The system is performing flawlessly. I am very satisfied with this kit. I look forward to putting it to the test towing in the Colorado mountains. I will be purchasing your intake for this same truck as well as probably upgrading my stock turbo to one of your new ball bearing turbos in the near future. I will not hesitate to recommend you guys to anyone who asks.
