Our Story
SigmaTurbo.com.au was founded in 1998 by a small group of passionate owners who recognised that the Mitsubishi Sigma Turbo GH Series was a truly special piece of Australian automotive history — and one that risked being forgotten.
Built between 1980 and 1983, the GH Series Sigma Turbo was one of the first turbocharged family cars sold in Australia. Powered by the Mitsubishi G54B 2.6-litre turbocharged four-cylinder engine, it offered genuine performance in a practical package — and earned a loyal following that continues to this day.
Today our community includes owners, restorers and enthusiasts from across Australia and around the world. Whether you're hunting for a rare parts diagram, looking for advice on a restoration, or simply want to connect with people who share your passion for this cult classic — you're in the right place.
