Fummins Conversion Kit FAQs (Cummins engine into Ford truck)
Fummins = Ford truck with Cummins engine swap. These swaps are popular for replacing failed Power Strokes or building ultimate towing rigs.
Why Fummins needs different turbo approach:
- Ford chassis constraints: Steering components, crossmember placement, and hood clearance differ from Dodge trucks
- Custom mounting requirements: Ford engine bay wasn't designed for Cummins dimensions
- Exhaust routing challenges: Downpipe and exhaust path different from factory Dodge applications
- Intercooler location: Ford intercooler placement requires custom charge piping
Our Fummins kits address these challenges with turbo systems proven to fit Ford chassis, properly routed piping, and mounting solutions that work around Ford-specific obstacles.
Common Fummins platforms we support:
- 1999-2003 F-250/F-350 7.3L chassis (most popular for 12V swaps)
- 2003-2007 F-250/F-350 6.0L chassis (popular for 5.9L 24V swaps)
- 2008-2010 F-250/F-350 6.4L chassis (good for 5.9L or 6.7L swaps)
- 2011+ F-250/F-350 6.7L chassis (less common, more wiring complexity)
Turbo choice depends on your power goals and Cummins engine:
12-Valve Mechanical Fummins (most common):
- 400-500 HP: S300 single turbo (S362, S366) - great street/tow balance
- 500-650 HP: Larger S300 or S400 single (S369, S472, S475) - more aggressive
- 650+ HP: Compound turbo system (S300/S400 or S400/S400) - best for heavy towing at high power
24-Valve VP44 or Common Rail Fummins:
- 400-550 HP: S300 single or VGT upgrade - excellent daily/tow
- 550-700 HP: S400 single or S300/S400 compounds - serious performance
- 700+ HP: S400/S400 compounds with big injectors, dual CP3s, etc.
6.7L Cummins Fummins (less common but awesome):
- 450-600 HP: VGT upgrade or S300 single - maintains good drivability
- 600-750 HP: S300/S400 compounds - optimal for this platform
Hood clearance considerations:
- Single turbos usually fit under stock Ford hoods
- Compound setups may require cowl hood or hood modification (depends on Ford year and turbo sizes)
- We can provide height measurements before you order
Not sure? Tell us: Ford year/model, which Cummins engine, your power goals, typical use (towing weight, daily driving, etc.). We'll recommend the right turbo configuration.
Power potential matches standard Cummins applications:
12-Valve Fummins:
- Stock P-pump with turbo upgrade: 350-450 HP
- Modified P-pump + turbo: 450-600 HP
- Built P-pump + compounds: 600-800+ HP
- Advantage: Mechanical injection = simpler, no electronics to integrate with Ford
24-Valve VP44 Fummins:
- Tuned with turbo upgrade: 400-500 HP
- Injectors + turbo: 500-600 HP
- VP44 limitations: Pump tops out around 600 HP reliably
Common Rail (5.9L or 6.7L) Fummins:
- Tuned with single turbo: 450-600 HP
- Compounds with injectors: 600-750 HP
- Full build (compounds, dual CP3s, etc.): 750-900+ HP
Real-world Fummins examples:
- 2001 F-350, 12V P-pump, S366 single: 475 HP - excellent daily/tow truck
- 2005 F-250, 5.9L 24V, S369/S475 compounds: 625 HP - hot-shot hauler
- 2008 F-350, 6.7L, S300/S400 compounds: 710 HP - competition pulling truck
Supporting modifications needed: Same as standard Cummins builds (injectors, fuel system, transmission, etc.). The Ford chassis doesn't limit power—supporting mods do.
A Fummins conversion requires solid mechanical skill and planning, but many experienced DIY builders complete these swaps at home. Diesel Power Source Fummins kits are engineered to reduce fabrication around turbo and airflow components. Some owners choose professional installation depending on experience, tools, and timeline.
Our Fummins kits include everything for the turbo system:
- Turbocharger(s): Single or compound turbos sized for your power goals
- Exhaust manifold: High-flow manifold compatible with Fummins applications
- Turbo pedestal/mounting: Adapts turbo to manifold
- Intercooler piping: Custom routing for Ford chassis (charge pipes from turbo to Ford intercooler location)
- Oil lines: Feed and drain with proper fittings
- Downpipe: Turbo outlet to exhaust system connection
- All hardware: Gaskets, clamps, bolts, studs
- Installation instructions: Fummins-specific guidance
What you'll need to supply (typical Fummins swap components):
- Completed Cummins engine swap with mounts and wiring
- Ford chassis and existing intercooler (or upgraded intercooler)
- Exhaust system from downpipe back
- Tuning for your Cummins ECM (12V needs injection pump setup, 24V/6.7L need ECM tuning)
Note: These are turbo system kits for already-swapped trucks. We do not provide engine mounts, transmission adapters, wiring harnesses, or other swap components—just the turbo performance system.
Ford chassis presents different clearance issues than Dodge trucks:
1. Steering system interference:
- Ford steering box and linkage are positioned differently than Dodge
- Turbo downpipe routing must clear Ford steering components
- Our kits account for Ford steering geometry
2. Crossmember and front axle clearance:
- Ford crossmember placement affects oil pan and downpipe routing
- 4WD front axle positioning differs from Dodge
- May require specific oil pan choice (consult during swap planning)
3. Hood clearance:
- Ford hoods have different contours than Dodge
- Tall compound setups may require hood modification or cowl hood
- We can advise on hood clearance based on your Ford year and turbo choice
4. Intercooler piping routing:
- Ford intercoolers mount differently than Dodge
- Custom charge piping path needed from turbo to Ford intercooler location
- Our kits include piping designed for Ford routing
5. A/C and power steering interference:
- Ford accessory drive layout differs from Dodge
- A/C compressor and power steering pump may need relocation or bracket changes
- Plan for this during swap—turbo upgrades work around existing setup
Our recommendation: Before ordering turbo kit, send us photos of your completed Fummins swap showing engine bay, clearances, and any custom work. We'll confirm fitment and recommend any adjustments.
Same EGT benefits as Dodge Cummins applications—200-300°F improvement.
Why Fummins owners love turbo upgrades for towing:
- Ford chassis + Cummins torque: Already a great towing platform, turbo upgrades make it exceptional
- EGT control: Single turbo drops EGTs 150-200°F, compounds drop 200-300°F
- Ford frame and suspension: Can handle heavy loads that Cummins power enables
- Reliability: Cooler EGTs protect your Cummins investment in the Ford chassis
Typical towing improvements:
- Before (stock Cummins turbo): 1,400°F towing 18k lbs up grades
- After (DPS single turbo): 1,200°F same load, better response
- After (DPS compounds): 1,050-1,150°F, massive confidence improvement
Fummins towing advantages:
- Ford Super Duty suspension handles weight well
- Cummins torque curve perfect for heavy loads
- With proper turbo setup, can outperform both stock Power Stroke and stock Dodge Cummins
