Building a 1979 Little Red Express from a Cummins diesel on out, including compound turbos; down the block from Ekstensive, the father-son team at Wide Open Garage builds a Samurai lake crosser from the ground up.

The father-son team at Wide Open Garage have their hands full converting a rusted shell of a Suzuki Samurai into a rock-crawling mega-truck; a customer arrives at Mod Mafia with a big problem: their Jeep Gladiator isn't safe to drive.

A request about a 1947 Ford truck becomes 1 Way Diesel Performance's next ground-up build; Mod Mafia jumps into uncharted territory with a Viper ACRX race car.

Mod Mafia transforms a fire-damaged M1038 Humvee ambulance into an extreme camping overlander; the Wide Open Garage team builds a bulletproof race car for the appropriately billed Death Car Race, in which drivers are blindfolded.

Looking into what happens if a Cummins diesel engine is put into a 2004 Lamborghini Gallardo; a customer wants Wide Open Garage to turn an old, rusted Chevy truck into a lifted, all-terrain truck on huge 74-inch tires.

Putting a twin-turbo Cummins into a 2004 Lamborghini Gallardo is a monster build unlike any other for 1 Way Diesel Performance. YouTube's "Unspeakable" star Nathan Graham asks Mod Mafia to help him out of a jam with his all-terrain, amphibious SHERP.
