Mitsubishi Aust chose not to do a lot of things like import performance cars that were being sold elsewhere. Turbocharging was only coming into popularity in the 80's so they took a car that was already in production and designed a carbied turbo setup inhouse - and the GH turbo was born. Then they did weird stuff like get the EU/US FWD Sigma and cut the biatch down the middle and turn it into a widebody variant - voila! Say hello to the Australian Magna. Our Starions (Conquest) got sohc 4G63 ECI turbos (WHICH WEREN'T WIDEBODY ), Cordias managed a 4G62 ECI turbo in FWD only. We did get VR4 Galant turbos which were, and still are, pretty awesome. After that it's EVO, EVO, EVO...
