Extreme Dimensions Carbon Fiber Wings Spoilers The 240SX is a two-door compact car that was introduced to the North American market by Nissan in 1988 for the following model year. It replaced the outgoing 200SX (S12) model. All versions of the 240SX were equipped with the 2.4-liter 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 based on the Nissan S platform. The 240SX is closely related to other S platform based vehicles, such as the Japanese-market Silvia and 180SX, and the European-market 200SX.
