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.
