This 1971 Mazda RX-2 was built by Curran Brothers Racing in New Zealand. Many will recognize both the name and car as they have been serious contenders in rotary drag racing for years.

When the RX-2 was first built it was powered by a twin-turbo two-rotor 13B. Soon after the engine was changed to a three-rotor peripheral-ported 20B..via(engineswapdepot)

With that engine the crew ran both a twin-turbo and triple-turbo setup. The engine produced around 1,300+ horsepower.

The engine was fitted with a huge single GT60 turbocharger and was capable of producing 1,600+ whp on 30-32 psi of boost.With this level of power the real failure point was the transmission. So CBR went with a Lenco CS3 air-shifted five-speed transmission.
