The 1991 Porsche 911 Carrera 4 has been radically reimagined by Russell Built into “Baja Prototype 01,” a machine that redefines the Safari-style aesthetic. Originally a cabriolet, this vehicle was converted into a lightweight coupe with a composite widebody and a chromoly tube chassis grafted onto the factory tub. Debuted at the 2019 SEMA show, this build emphasizes extreme durability and off-road capability without sacrificing Porsche’s legendary air-cooled soul. It serves as a functional masterpiece of rally engineering, currently showing 6k miles and offered with a clean Indiana title.
Rally-Ready Widebody and Composite Aerodynamics
The silhouette of this 911 has been transformed with louvered fenders, a carbon fiber roof scoop, and a massive whale-tail rear spoiler. Its functional tech includes an auxiliary light pod integrated into the hood, LED headlights with polycarbonate covers, and steel bumper guards for protection against harsh terrain. The undercarriage is equally prepared, featuring comprehensive skid plates and red accent lighting to highlight the intricate suspension work. While the body exhibits minor blemishes from its adventurous life, the custom mudflaps and textured rock guard panels confirm its readiness for high-speed desert crossings.
Carbon-Fiber Racing Cockpit with Olive Leather
Inside, the cabin is a blend of motorsport utility and bespoke craftsmanship, housing Sparco SPX carbon-fiber bucket seats. These seats are trimmed in unique olive green leather with black quilted Alcantara inserts, secured by red six-point harnesses. A 4130 chromoly roll cage protects the occupants, while the dashboard and door panels are wrapped in matching leather. Technical controls include a Tilton Racing pedal assembly, a 7-inch MoTeC digital instrument panel, and custom switchgear. This environment is specifically insulated with spray-in ceramic coating to manage heat and noise during grueling off-road stages.
Rothsport Racing Power and Long-Travel Suspension
Mechanical performance is anchored by a 3.8L flat-six built by Rothsport Racing, featuring individual throttle bodies and a MoTeC ECU. While exact output figures are not provided, this engine delivers a visceral, high-revving response paired with a GT3-style exhaust. The car utilizes an all-wheel-drive system and a six-speed manual transaxle sourced from a 996 Turbo. The suspension is the highlight of the build, offering 12 inches of front travel and 14 inches of rear travel via three-way adjustable Elka Stage 5 shocks. This setup allows the 1991 Porsche 911 Carrera 4 to benchmark against dedicated desert trophy trucks.

It benchmarks favorably against the Porsche 911 Dakar or the Lamborghini Huracán Sterrato, offering a more raw, air-cooled experience with superior suspension articulation. As “Prototype 01,” it holds significant historical value as the car that launched one of the most respected names in modern Porsche tuning.
Engineering Excellence for Desert Durability
Ownership of Baja Prototype 01 provides a level of capability that few street-legal vehicles can match. The fuel system is modernized with a fuel cell and Radium Engineering surge tank, ensuring consistent delivery during high-G maneuvers. The 16-inch white Rotiform wheels are wrapped in Toyo Open Country A/T tires, designed to provide maximum traction across diverse surfaces from sand to silt. With its Indiana title and damage-free Carfax history, this Porsche is ready for its next owner to either continue its show-winning legacy or put its 14 inches of travel to the ultimate test in the Southwest deserts.

The Russell Built 1991 Porsche 911 Carrera 4 Safari is a breathtaking fusion of 964-generation heritage and modern off-road racing technology. Every component, from the olive leather upholstery to the Elka shocks, has been selected to serve a dual purpose of form and function. It is a vehicle that commands attention at SEMA and respect on the rally trail.
