The Nissan 240SX (also known as the 180SX in Japan) 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.
Automatic models featured Nissan's "DUET-EA" system, an electronic link between the engine control module (ECM) and the transmission designed to facilitate smoother, more controlled shifts. Many users have been known to circumvent this system however in favor of a more "sports car" feeling to the ride, similar to that of an aggressively shifted manual transmission.
As the cars have aged, Japanese I-4 SR20DET, I-4 CA18DET, I-6 RB series, and V-6 VQ35DE engine swaps have become an increasingly popular 240SX modification. At the same time, a large community has developed of owners turbocharging the 2.4-litre KA engines. The stout stock rear end and accommodating engine bay has even lead to rarer, more drastic engine swaps, included the V-6 Nissan VQ series and V-8 General Motors LS series.
It is also popular for owners to import body parts from the Japanese-market S13 Silvia and install them onto their S13s (to make a Sileighty out of the hatchback and Silvia clone for the coupe and convertible) or the 1996-1998 Kouki 180SX Type X and install them on their S13s. Owners of 1995-96 240SXs often change the exterior to the S14a Kouki look. Since the three modern S-chassis cars (S13, S14, and S15) have similar widths, there are aftermarket conversion kits that allow buyers to add the front clip of one generation to be attached to another generation S-car. These conversions include the S13.4 (S13 chassis with S14 front end) S13.5 (S13 chassis with S15 Silvia front end), and S14.5 (S14 chassis with S15 Silvia front end). Other swaps have been recorded such as a 240Z front end on a S13, an S14 with S13 (pop-up headlights) front end (S14.3), and a S13 with R32-chassis Skyline front end. Wikipedia |
