Nismo (abbreviated from Nissan Motorsport International Limited (, Nissan Mt Suptsu Intnashonaru 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 and the Blancpain GT Series.
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 mori Works (Special Car Testing Division), within its mori 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.
Nismo designs and manufactures a range of aftermarket performance parts for Nissan cars including Aerodynamics parts such as spoilers and diffusers, alloy wheels, engine and suspension parts. The 2017 Infiniti Q60, being much criticized for its mild exhaust sound, about six months after its introduction had a specially tuned Nismo muffler made available through Infiniti dealers as an aftermarket item.
Most Datsun, Nissan, and Infiniti branded cars have performance parts available from Nismo, either in production or as old stock. For example, Nismo sells parts such as unground cam billets, performance cams, pistons, etc. for the KA24E engine, which was used in the Nissan small pickup truck for several years and also used for the 1989 and 1990 model years of 240SX, a popular car among Import scene enthusiasts (especially Drifters) in North America.
In Japan, the V35 Skyline and Z33 Fairlady have both received several levels of Nismo tuning packages (E-Type, S-Tune, R-Tune, and S1 packages), with a full track spec Fairlady Z debuted at the 2005 Nismo Festival of Speed held at (formerly) Fuji International Raceway.
In February 2007, Nismo announced the launch of the Nismo 380RS. The Nismo 380RS is a factory modified version of the Nissan Z33 Fairlady Z tuned by both Nismo and Autech. Two versions were released, the first was a track-only model called the 380RS-C (C for competition), the second is a street model being sold at Nissan dealers. Both versions use a Nissan VQ series V6 engine, bored and stroked to 3.8L. The track-only 380RS-C makes 400 hp (298 kW), and the street version makes approximately 350 hp (261 kW). The Nismo 380RS was only sold in Japan.
