As a result, the Tacoma X-Runner RTR is a “parts bin” build with all but a few components currently available on Toyota products (traction bars and drive-line shaft are the only two non-Toyota parts).
Power comes from a completely stock, current-generation Tundra 5.7-liter V-8 engine, which is matched to a six-speed automatic transmission. A Toyota Racing Development (TRD) supercharger kit was added, bringing output to 504 horsepower and 550 pound-feet of torque.
To improve drivability, a narrowed Tundra rear axle, with a 4.3 ratio and 10.5-inch ring gear, was added, as well as a TRD prototype mechanical limited slip differential that was designed by Eaton. The truck rides on current generation Tacoma 15 inch styled steel wheels that were modified to 10 inches wide in the rear and wrapped by Goodyear Eagle Dragway Specials. The front wheels are 4.5-inches wide and mounted to Goodyear Eagle Front Runners.
Other modifications include a lowering kit, which drops the vehicle 4.5 inches, a custom exhaust system, and a new silver and red paint scheme applied by Five-Axis.
Inside, all non-essential equipment was removed to make the vehicle as light as possible, including the audio head unit, speakers, air conditioner, power windows, front fog lamps, windshield water bottle, and rear seats. The stock front seats remain but are covered with classic Toyota fabric trim found on 1980s era vehicles. Added interior features include a custom TRD steering wheel, Tundra stock accelerator and brake pedals, and a stock Tundra gated shifter with sport shift mode. A TRD designed removable roll bar was also installed.
Look out for this wild Tacoma at this year’s SEMA show, which kicks off on November 2.
