Photo 3/22 | 2004 Ford Excursion Engine Full | At the heart of this awesome swap is a 6.7L Cummins engine that was pulled from a donor vehicle with only 30,000 miles on it. The heavily modified powerplant makes an estimated 600 hp, all the while knocking down 17 to 18 mpg on the freeway.
Photo 4/22 | 2004 Ford Excursion Compound Turbos | A big contributor to the engine’s impressive power is this compound turbocharger setup, which was built by Destroked.com. The smaller of the two turbos is a 64mm ’charger, which is fed by a 75mm S400. Capable of up to 70 psi of boost, the turbos spool just fine in high altitude, thanks to the 6.7L’s extra cubic inches.
Photo 5/22 | 2004 Ford Excursion Edge Cts | Monitoring of the drivetrain is done through a single Edge CTS monitor, which most of the time is set to display boost, EGT, fuel pressure, and engine coolant and oil temperatures.

Photo 8/22 | 2004 Ford Excursion Dual Cp3 | An ATS Performance Diesel dual CP3 kit features a custom pulley from Destroked.com. The twin pumps feed a set of 120hp injectors from Dynomite Diesel Performance.
Photo 9/22 | 2004 Ford Excursion Electonics | The 6.7L's computers were swapped into the Excursion’s engine bay in a way that makes everything almost look like Excursions were equipped with Cummins engines from the factory. Tuning is handled by a MADS Smarty Performance programmer.
Photo 10/22 | 2004 Ford Excursion Radiator And Intercooler | Marshall incorporated as many stock parts into the build as possible for maximum reliability. One piece that was upgraded, however, is the intercooler, which is a higher-flowing unit designed for Excursions by Banks Power.
Photo 11/22 | 2004 Ford Excursion Exhaust | There's not much at the rear of the truck that clues folks in about what's going on under the hood. A simple 4-inch exhaust built by Destroked.com sends engine gases away from the SUV.
Photo 12/22 | 2004 Ford Excursion Trans Pan | Marshall really wanted a six-speed transmission, so an Allison 1000 automatic got the nod for the project. Built by Destroked.com, the transmission features a low-stall converter and stand-alone controller that allows it to run with the Cummins engine and in the Ford chassis without any issues.
Photo 13/22 | 2004 Ford Excursion Wheels And Tires | With the effort Marshall put into building his dream SUV, he wasn't about to leave the suspension alone. He wanted a Lincoln Town Car ride, along with increased capabilities, so a set of custom-arched springs from Deaver was installed, which give the truck roughly a 3-inch lift. The wheels are from KMC, while the tires are 285/75R18 Nitto Terra Grapplers.
Photo 14/22 | 2004 Ford Excursion King Shocks | In addition to the custom springs, King shocks were added to all four corners of the Excursion for added on- and off-road handling performance.
Photo 15/22 | 2004 Ford Excursion Rear Airbags | Since the truck tows on a regular basis, air springs were installed in the rear to keep everything level when the SUV is loaded down.
Photo 16/22 | 2004 Ford Excursion Multi Plug For Trailer | A lot is going on in the back of the Ford. There are off-road lights, a multi-plug trailer/brake controller assembly, and fittings for quickly filling the rear airbags.

Photo 18/22 | 2004 Ford Excursion Interior Shot Full | Marshall went with the if it isn't broken, don't fix it, motto with the interior, which, other than a few extra switches, is just factory Ford Excursion.
Photo 19/22 | 2004 Ford Excursion Veggie Oil Tank | For extended trips up in the mountains, Marshall designed his own vegetable-oil fuel system, which he uses after the engine is warmed up and has run for a while on regular diesel.
