just like the old old celica were called 2000GT (2.0 liter straight 4)... the 3.0 GT supras were called 3000GT (3.0 liter straight 6)... In the US the mitsubishi 3000GT are called GTO in Japan and everywhere else.. because of the copyright stuff with the GM.. Pontiac GTO.. they had to use the 3000GT name since it was not used... the 3000GT is also sold as Dodge Stealth..
remember the old gran turismo games where you can tune your GTO to 939 hp or something n it killed every other cars > p
