Was just reading up on the history of Hondas V6 (C)engine series From the C20A all the way to the C35B and I came across something interesting. Hondas 2nd production Turbo engine the C20AT V6 produced for only one year that was found as a high performance option over the C27A in the Honda Legend sports sedan. If the price jump for the turbo option wasnt so huge and the sales so poor that Honda may have went with the main stream in Japan at the time and started using Turbo engines in there sports cars, just think a C30AT & C32BT wow the NSX would have been unstoppable. The C20AT was a turbocharged version, called the Wing Turbo, producing 190 bhp (141.7 kW; 192.6 PS). Japan only: 1989 Honda Legend Honda replaced the variable length intake manifold with a variable geometry turbocharger to the C20A engine used in the Japanese Domestic Market Legend. The turbo with intercooler-equipped engine was the C20AT engine and are extremely rare. Honda pioneered variable-geometry turbo chargers. The Wing Turbo, as Honda called them, were controlled by an 8-bit processor ECU and they were constantly adjusting. Basically, at low speeds the wings surrounding the turbine wheel inside the compressor housing on the intake side would be nearly closed to speed and direct exhaust pressure precisely on the turbine wheel. At 2000 rpm, the wings would fluctuate and it would act like a much larger turbo to increase fuel economy as needed. This car was quick and powerful, but the price premium over the slightly longer and wider Legend with the 2.7 L naturally aspirated V6 was too much for most, so the car disappeared. This was one of the only production Hondas ever turbocharged from the factory (excluding turbo engines of kei car for the Japan domestic market), along with the K23A1 straight-4 engine used in the Acura RDX and the ER straight-4 engine used in the first generation Honda City.
