Nissan SX 240 Generations & Specs: A Complete Guide

The Nissan 240SX is a sports compact car that was introduced to the North American market by Nissan in 1989 for the 1990 model year. It replaced the outgoing 200SX (S12) model. Most of the 240SXs were equipped with the 2.4-liter inline-four engine (KA24E from 1989 to 1990 and KA24DE from 1990 to 1998). The KA24E had a single overhead cam, while the KA24DE had dual overhead cams. Two distinct generations of the 240SX, the S13 (1989–1994) and the S14 (1994-1998), 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. Although their names are similar, the 240SX is unrelated to the 240Z or the 280ZX.

The 240SX is known for its popularity within drifting and tuner culture. However, due to the popularity of the S-chassis in drifting and related competitions, prices for vehicles and parts have greatly increased due to higher demand. This problem is sometimes known as “drift tax.”

First Generation (S13; 1989–1994)

The first generation of the 240SX can be divided into two distinct versions: the hatchback, which was offered in base, SE, and LE trims, and the coupé, which was offered in base, XE, LE, and SE trims. Both styles shared the same front bodywork as the Japanese-market Nissan 180SX, featuring a sloping front with pop-up headlights. This front bodywork distinguishes the coupé model from its Japanese-market counterpart, the Silvia, which featured fixed headlights. Both styles in all markets share the same chassis, and with few exceptions, most components and features are identical.

  • 1989-1990
    • Engine: KA24E
    • Power: 140 hp
    • Transmission: 5-speed manual / 4-speed auto
    • Features: Pop-up headlights, HUD in some trims

    • Power: 155 hp
    • Transmission: 5-speed manual / 4-speed auto
    • Features: Sports package with LSD and ABS

In 1991, the 240SX received some updates. The matte silver, teardrop wheels were replaced by polished aluminum 7-spoke wheels that had better brake cooling properties. The nose was smoothed out by getting rid of the non-functional slots, improving aerodynamics. A new “LE” hatchback trim package was added that included a leather interior. The SOHC KA24E was replaced by the DOHC KA24DE, now with 4 valves per cylinder, rated at 155 bhp at 5,600 rpm and 160 lb-ft of torque at 4,400 rpm. An optional sports package including ABS, a limited-slip differential, and Nissan’s HICAS four-wheel steering was now available on hatchback models.

Second Generation (S14; 1994–1998)

The second generation 240SX was released in the spring of 1994 as a 1995 model. The hatchback and convertible body styles were eliminated, leaving only the coupe. The wheelbase of the car grew by 2 inches, and the track width was also increased, while the overall length of the vehicle was slightly shorter than the previous generation.

  • 1995-1996
    • Engine: KA24DE
    • Power: 155 hp
    • Transmission: 5-speed manual / 4-speed auto
    • Features: Dual airbags, increased chassis stiffness
  • 1997-1998
    • Engine: KA24DE
    • Power: 155 hp
    • Transmission: 5-speed manual / 4-speed auto
    • Features: Kouki facelift, projector headlights

The S14 carried over the KA24DE engine from the S13, producing the same 155 hp and 160 lb-ft of torque, but featured internal revisions for improved throttle response and reduced shake and vibration. This generation of the 240SX suffered in sales due to competition from other car manufacturers and consumers choosing more practical vehicles, such as SUVs. In this generation, every 240SX was built in Kyūshū, Japan. The last 240SX rolled off the assembly line on July 23, 1998.

My Thoughts on the Nissan 240SX

The Nissan 240SX is one of the most influential JDM sports cars in North America. While the KA24E and KA24DE engines were not the most powerful, they were incredibly durable, making them perfect for modification. The S13 is more commonly used for drifting due to its lighter weight and pop-up headlights, which give it a classic 90s look. On the other hand, the S14 is more refined and better suited for street driving.

Despite their increasing rarity and the drift tax driving up prices, these cars remain a solid choice for enthusiasts looking for an engaging, rear-wheel-drive experience. The aftermarket support is immense, and with the right modifications, the 240SX can rival much more expensive sports cars in performance. Whether you prefer the raw and lightweight feel of the S13 or the more stable and modernized S14, the 240SX remains an icon in tuner culture.
