The Technigold motor is perhaps the most known Tamiya motor still. It’s the descendant of the Technipower and Technituned motors released about 1,5 years earlier. The Technigold took a big step forward in performance, with massive increase in torque with still great RPM. The motor was supplied as standard in: • 58057 Bigwig • 58059 Porsche 959 • 58046 Toyota Celica • 58072 Avante.
