This Thunder Ranch 550 Spyder replica is powered by a turbocharged and intercooled 2,276cc air-cooled flat-four equipped with dual Dell’Orto DRLA carburetors, MSD ignition, a Turbosmart boost controller, and a Snow Performance methanol injection kit. It is finished in silver over red upholstery and equipped with 15″ steel wheels, four-wheel disc brakes, aluminum drum covers, a four-speed manual transaxle, a hydraulically-actuated clutch slave cylinder, and a Jamar Performance shifter as well as a driver’s helmet fairing, a left GT-style mirror, a Halon fire suppression system, and a dual-grille engine cover with leather hold-down straps. The car was assembled in the 1990s, refreshed in 2009, and acquired by the selling dealer in 2024. The fiberglass bodywork is mounted to a tubular steel frame and is finished in silver. Exterior details include a driver’s helmet fairing, gold-finished Porsche and Spyder badging, a GT-style mirror, mesh headlight grilles, Wendler fender badges, a Le Mans-style fuel filler, and a dual-grille engine cover with leather hold-down straps. Steel 15″ wide-five wheels are mounted with 195/50 front and 205/50 rear Yokohama tires. Stopping power is provided by four-wheel disc brakes with aluminum drum covers. The tires were replaced, the brake fluid was changed, and the front caliper slides were removed and lubricated in June 2024. The fixed-back bucket seats are trimmed red upholstery and are joined by color-coordinated carpeting and door panel inserts. Interior elements include a height-adjustable rearview mirror, a passenger grab handle, a Jamar Performance shifter, and a 550-style parking brake.
