This Mini was built by Retropower in Hinckley, England. The company rebuilt the small car with a 2.1 L C20XE inline-four that makes 240 horsepower. The engine features CP forged pistons, Williams Motorsports steel rods, ported head, Isky double valve springs, Arrow solid lifters, upgraded camshafts, and Jenvey direct-to-head throttle bodies. Power goes to the front wheels through a Vauxhall F20 transmission with a Quaife gear set and Gripper LSD. Other upgrades include Corsa electric power steering rack and KAD disc brakes front and rear.
