Nismo (abbreviated from Nissan Motorsport International Limited (ニッサン・モータースポーツ・インターナショナル株式会社 Nissan Mōtā Supōtsu Intānashonaru Kabushiki-gaisha)) is the in-house tuning, motorsports and performance division of Nissan. Formed in 1984 as a result of a merger of two motorsport departments, Nismo cars have participated in JSPC, JTCC, 24 Hours of Le Mans and 24 Hours of Daytona. They currently participate in the Super GT, the Blancpain GT Series and WeatherTech SportsCar Championship.
In 1984, Nissan decided that it wanted to merge its two motorsport divisions, founded through the 1960s, they were Oppama Works(known as Publication Division 3), based in its Oppama factory, responsible for the needs of privateer teams and Ōmori Works (Special Car Testing Division), within its Ōmori plant, responsible for its factory operations. The company's intention following the merger was to specialize in sportscar racing, but it also provided support for teams competing in the domestic F3 series.
In 1988, NISMO built its first car, the Saurus for motorsport use for its one-make series. The following year they developed the Skyline GT-R for racing as well as building the 500 evolution editions for road use.
