The 2.4 L (2389 cc) KA24DE was used in many Nissan cars and trucks. Most KA24DEs bound for the US were built in Aguascalientes, Mexico, with the exception of the 240SX, which was manufactured in Fukuoka, Japan. The Nissan 240SX was a car introduced to the North American market by Nissan in 1989 and sold there until 1998. It replaced the 200SX (RWD) in 1989. The 240SX was equipped with a 2.4-litre inline 4 engine (KA24E from 1989-1990 and KA24DE from 1991-1998). Two distinct generations of the 240SX, the S13 (1989-1994) and the S14 (1995-1998), were produced from the Nissan S platform. The 240SX is closely related to other S vehicles: the Japanese-market Silvia and 180SX and the European/Australian-market 200SX. Many enthusiasts are turbocharging, creating the KA24DE(T) engine code.
