NOTE: Honda made a "Wing-Turbo" Legend marketed under the Honda name and was only available in the Japanese Domestic Market. It was very rare and it had the turbocharged C20AT engine in it. The turbocharger used was a Variable Geometry turbo that Honda developed. The turbo used aerofoil style flappers all around the the turbine housing. These "Wings", as Honda called them, were controlled by vacuum and by the Legend's ECU and they were constantly adjusted. Basically, at low speeds the wings would be nearly closed to speed and direct exhaust pressure precisely on the turbine wheel. At cruise speeds, the wings would be open and it would act like a much larger turbo to increase fuel economy. This car was really quick and really powerful, but the price premium over the standard Legend was too much for most so the car disappeared. This was one of the only production Hondas ever turbocharged from the factory, along with the new Acura RDX and the older Honda City's.
