Air Pre-Filter Sock
Full kit for Ford Cummins conversion (Fummins Swap) includes both turbos (DPS 62/65/12 Turbo with a Borg Warner S475 Turbo). For Ford Truck models 1970 - 1997.
DPS 62/65/12 over S400 Turbo (75mm) - Baseline Kit Great for Towing
Full Compound Turbo Kit See Below for Details
Where else can you find a twin kit for your conversion? 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 spool up, and driveability they get from such a high performance kit. **SPOOL UP IS VERY SIMILAR TO STOCK TURBO.
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 300 - 600 horsepower applications (For large power, see our larger kits).
**Note: New model ford trucks may not fit our intercooler hose, due to a change in Ford's intercooler location.
This Fummins Conversion 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.
Fummins Kit includes: Air Filter, Cast 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 62 Turbo (small turbo, 62/65/12),1-S475 Turbo (large turbo 75mm 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 S480 to exhaust pipe), V-Band Clamps, High Torque T-Bolt Clamps, Low Torque Clamps, Installation Instructions.
DPS Turbos are based on the S300 platform.
Note: The following test results are on our HT3B Twin Kit (the S475-S483 Twin Kits yield even better results).
EGT TEST RESULTS: The following test results were to test different single turbochargers against our Twin Turbo Kit (this test was on our HT3B twin kit which has less air flow than the S400 series kits). Each test consisted of a sustained 400hp dyno pull. The test truck was brought up to a 400hp on the dyno, and then loaded to hold a sustained loaded pull, equal to pulling a trailer up a grade using 400 hp. The EGT's were read pre-turbo. The results follow:
Reasons Why Our Compound Turbos Work So Well
**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.
** The standard kit is a DPS 62 over an S475. (You can upgrade the wheel sizes in either turbo for additional charges.)
When shipping to anywhere outside of the lower 48 states, additional shipping fees may apply.
Head Stud Recommendations:
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.
Thanks so much guys, fummins compounds fit like a glove. 97 f350 with 74k original miles , 6k on 24 valve Cummins & 47re swap ,shackle reversal , cross over steering and around 10 inch of lift .rolling on 37s .funny thing is I built this to pull our toy hauler. Can’t wait to pull with compounds. By the way I have to tell you I was skeptical of a fummins compound kit due to the lack of space but your guys on the phone assured me this kit would work. Wish I would have found you guys before I first installed my Cummins with a single BD turbo
This kit just fits! I went with the smaller 62/65 with s475 for my 2002 Excursion conversion. Best family tow vehicle. The kit fit and you told me I would have to modify the downpipe to fit and I just had a muffler shop do a custom fit downpipe and exhaust for me. We look forward to many more years of family camping with this new setup! Thanks DPS
