DPS S300 over S400 Turbo (75-83mm)
Race Compressor Housing (Flows 9% more air).
Full Compound Turbo Kit Includes Everything for Install
This Diesel Power Source Fummins compound kit is the most user friendlyford 6.0 to cummins conversion kit to fit on your Ford pickup with the Cummins engine conversion. Made to clear your heater A/C core. Other features include:
High Flow 3-Piece Exhaust Manifold included in kit, with built in pre-tapped pyro ports.
The largest air filter on the market.
Low pressure charge pipe is silicone with Kevlar/Nomex liner (which is easier to fit than a steel tube). Silicone tubing uses fewer clamps and has better flow characteristics than steel.
High pressure charge pipe is strong chrome plated aluminum.
Small turbo has a 150% greater wastegate capacity
Cast hot pipe, not flimsy welded exhaust pipe.
Flexible Steel braided oil supply lines, and stainless steel oil drain lines.
Polished DPS (small) turbocharger.
S400 with DPS 75mm 80 or 83mm Billet compressor wheel as atmospheric turbo
S400 Race Housing, with ported shroud inlet, flows amazing, has elbow outlet allowing very good fit. This race housing with elbow outlet is unique to our kit.
Support bracket for Lower (large) turbocharger.
Adjustable boost pressure.
Wastegated
Tons of other upgrade options: (Compressor wheel options on atmospheric turbo 75mm 80mm and 83mm, additional fees may apply)
Intercooler hose to fit the Ford intercooler.
Our Fummins Race Compressor Housing on the S400 Turbos for the ford 6.0 to Cummins conversion kit is unique to the DPS Fummins Twin Kits, giving our kit alone the ability to fit into the complex Ford Cummins Conversion Projects.
Our Ford 6.0 to Cummins conversion kitcomes with two separate oil drain lines (except for 12V engines that only have one oil drain port).
Where else can you find a twin kit for your Ford 6.0 to Cummins conversion kit.No where, but here. Even includes the intercooler hose to fit the Ford intercooler.
Diesel Power Source, Twin/Compound Turbo Kit, performs excellent when Racing, Towing, or Sled Pulling, but is very driveable. SPOOL UP IS SIMILAR TO STOCK, while raising airflow significantly. You'll be amazed at the spoolup, anddriveability they get from such a high performance kit.
EGT's are typically reduced by 300-500 degrees, over a single turbocharger.
Boost pressure will typically exceed drive pressure, which can't typically be done with a single turbocharger (with a single turbo, drive pressure is typically about double boost pressure).
Horsepower, and torque are increased throughout the entire RPM band, and significantly increased in mid and upper range.
Specifically tuned for 350 - 850 horsepower applications. (For less power, see our smaller kits).
Note: Newmodel ford trucks may not fit our intercooler hose, due to a change in Ford's intercooler location.
This Twin/Compound Turbo Kit was designed on cutting edge CAD/CAM Software, using CFD (Computational Fluid Dynamics) Testing. You will not find a more high tech kit on the market today. Everything fits like it was built from the factory.
Kitincludes:AirFilter, Cast Iron Hot Pipe, Support Bracket for S400 Turbo, 3-Piece Exhaust Manifold (pre-tapped ports for pyro), Complete Air Intake including Air Filter, Silicone Charge Pipe (on Low-pressure end), Chrome Plated Aluminum Charge Pipe, 1-DPS Turbo (small turbo, 64/71/12), 1-S 400 Turbo (large turbo 80mm Machined Billet compressor wheel/ 96m turbine wheel, 1.32 A/R Housing), 2-Steel Braided High Temp Oil Supply Lines, 2-Oil Drain Lines & Fittings, Turbo & Manifold Gaskets, Oil Line Adapters, Mounting Bolts, Exhaust Adapter (from S 400 to exhaust pipe), V-Band Clamps, High Torque T-Bolt Clamps, Low Torque Clamps, Installation Instructions.
DPS Turbos are based on the S300 platform and/or S400 platform.
EGT TEST RESULTS:The following test results were to test different single turbochargers against our Compound Turbo Kit. Each test consisted of a sustained400hpdyno pull. The test truck was brought up to a400hpon thedyno, andthen loaded to hold a sustained loadedpull, equalto pulling a trailer up a grade using 400 hp. The EGT's were read pre-turbo. The results follow:
Test 1 StockTurbo: MaxEGT's reached 1700 degrees, (Test Time: 13 seconds, operator ended test due to excessive EGT's).
Test 2 Competitors 62/65/13 Turbo: MaxEGT's reached 1700 deg (Test Time: 17 seconds, operator ended test due to excessive EGT's).
Test 3 Diesel Power Source Compounds: Max EGT's reached 1260 (Test Time: 1 minute, EGT's did not ever exceed 1261 degrees).
Reasons Why Our Compound Turbos Work So Wellfor the ford 6.0 to cummins conversion kit
The air entering the cylinders is cooler, because dual compressors work together within their most efficient zone. The boost air is typically over 100 cooler than from a single turbo.
The air entering the cylinder is at higher pressure, bringing the boost pressure and exhaust drive pressures near a 1:1 ratio. The intake stroke can actually produce power.
There are additional air molecules in the cylinder which do not get involved in combustion which carry the heat out of the cylinder (similar to how a jet engine is cooled).
It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.
**While a downpipe is not included in this kit, we do include a machined exhaust adapter/reducer which v-band clamps onto the exhaust outlet of the S400 turbo, so that a 4” or 5” exhaust pipe can be welded onto it. This makes it very convenient to attach whatever exhaust system you have.
** 1-Year, Limited Warranty.

Head Stud Recommendations:
2007.5-2012Engines: Headstuds if boost pressure over 50 PSI, Fire Rings over 55 PSI
2003-2007Engines: Headstuds if boost pressure over 55 PSI, Fire Rings over 65 PSI
1989-2002Engines: Headstuds if boost pressure over 48 PSI, Fire Rings over 55 PSI
Please note: Ford/Cummins, Chevy/Cummins or any other conversion kit are considered a custom application. The hardest part of these conversion kits are getting both turbos to fit in the truck and clear the heater core. Our compound kits are specifically designed to get both turbos to fit nicely. In most cases the intercooler hose will fit to a factory intercooler, and will allow the intake to fit as well, however because all of these conversion kits are so custom in nature it is the responsibility of the installer to tie in the intercooler, exhaust and intake tubing into the truck. This is because the engines, alternators, batteries, intercoolers, etc. can be done in some many different configurations it would be impossible for any single kit to universally fit every swap application. In most of the conversion applications, expect to do some fabricating to exhaust pipe, intake and/or intercooler tubing.
Great for your Excursion Cummins swap.
