Mitsubishi has utilized the "Sigma" name on several different vehicles based on Mitsubishi Galant and Mitsubishi Diamante sold in various markets during this time. The GSX-R 2.0 turbo model was fitted with a Single Overhead Cam cyclone motor which was the precursor to the infamous 4G63T twin cam motor.
