The Yamaha OX66 is a naturally aspirated V6 racing engine that Yamaha developed and built in the 1980s. Development began in 1984 as a design for a lightweight, compact Formula Two engine with a wide power band, intended to beat Honda's V6 in the Japanese series. It has a 75 degree bank angle, an aluminium block with replaceable cast iron wet liners, and a five valve head with three intake and two exhaust valves per cylinder, driven by timing belts. It was announced for the 1985 season and reached works and customer teams in 1986, the year Geoff Lees won the Grand Champion Series with it. Teams found its upkeep two to three times that of a BMW F2 engine, and the replacement of Formula Two by Formula 3000 ended its main career.
