1991-1994 Nissan 240SX Coupe (S13 facelift ) 2.4 (155 Hp)

The Nissan 240SX Coupe, specifically the S13 facelift model produced from 1991 to 1994, represents a pivotal point in the evolution of Nissan’s sporty compact offerings. This generation, often referred to as the “Zenki” (meaning “before” in Japanese, referring to the pre-1994 facelift), built upon the success of the initial S13 platform launched in 1989. The 2.4-liter (KA24DE) engine variant, producing 155 horsepower, occupied a middle ground in the 240SX lineup, offering a balance between performance and affordability. It was primarily marketed towards enthusiasts seeking a capable and customizable rear-wheel-drive coupe, a relatively rare offering in the American market at the time.

Introduction

The 1991-1994 Nissan 240SX Coupe, representing the facelift of the S13 chassis, was a two-door, four-seat coupe designed to appeal to a younger demographic. It was a direct successor to the previous generation 240SX (RS13) and shared its platform with other Nissan models of the era, including the Altima. The KA24DE 2.4-liter engine, producing 155 horsepower, was a key component of this variant. This engine and transmission combination was positioned as a more accessible entry point into the 240SX range, offering a balance of performance and fuel efficiency compared to the more powerful (and expensive) turbocharged SR20DET engine available in Japanese market models.

Powertrain & Engine Architecture

The heart of the 240SX Coupe 2.4 is the KA24DE engine. This 2.4-liter inline-four cylinder engine features a cast iron block and an aluminum cylinder head. It utilizes multi-port fuel injection, delivering fuel directly into each intake port for improved combustion efficiency. The engine employs a double overhead camshaft (DOHC) valvetrain, operating 16 valves (four per cylinder) to optimize airflow and enhance performance. The KA24DE is known for its relative simplicity and durability. The 240SX typically came equipped with a five-speed manual transmission, providing drivers with full control over gear selection. The transmission’s gear ratios were tuned to provide a balance between acceleration and cruising efficiency. While an automatic transmission was offered, the manual was favored by enthusiasts for its more engaging driving experience.

Driving Characteristics

The 240SX 2.4 with the five-speed manual transmission offered a responsive and engaging driving experience. While not exceptionally powerful, the 155 horsepower engine provided adequate acceleration for everyday driving and spirited backroad excursions. The rear-wheel-drive layout contributed to a balanced chassis and predictable handling. The manual transmission allowed for precise gear changes, maximizing the engine’s power output. Compared to the automatic transmission version, the manual offered a more direct connection between driver and machine. The automatic, while providing convenience, resulted in noticeable power loss and a less engaging driving experience. The 240SX’s relatively lightweight construction further enhanced its agility and handling characteristics.

Equipment & Trim Levels

The 240SX Coupe 2.4 typically came standard with features such as air conditioning, power steering, and an AM/FM stereo. Interior upholstery was typically cloth, with options for upgraded materials available. Dashboard configuration was relatively simple and functional, prioritizing driver information. Optional extras included a sunroof, upgraded sound system, and alloy wheels. The 240SX was not a luxury vehicle, but it offered a comfortable and well-equipped interior for its price point. Trim levels varied slightly depending on the year and region, but generally focused on cosmetic enhancements and convenience features.

Chassis & Braking

The 240SX Coupe utilized an independent McPherson strut suspension in the front, providing responsive steering and comfortable ride quality. The rear suspension employed a multi-link setup with coil springs and telescopic shock absorbers, contributing to stable handling and good road grip. Braking duties were handled by ventilated discs in the front and solid discs in the rear. The braking system was adequate for the vehicle’s weight and performance, but lacked the stopping power of more modern braking systems. A transverse stabilizer bar was included both front and rear to reduce body roll during cornering.

Market Reception & Comparison

The 1991-1994 Nissan 240SX Coupe was generally well-received by automotive critics. It was praised for its balanced handling, responsive steering, and affordable price. The KA24DE engine was considered reliable and durable, although not particularly powerful. Compared to the turbocharged SR20DET engine available in Japanese market models, the KA24DE offered less performance but greater reliability and lower maintenance costs. Fuel economy was respectable for a sports coupe of its era. The 240SX faced competition from other sporty coupes, such as the Mazda MX-5 Miata and the Toyota Celica, but its rear-wheel-drive layout and customizable nature set it apart.

Legacy

The Nissan 240SX Coupe has achieved a cult following among automotive enthusiasts. Its rear-wheel-drive layout, relatively simple mechanicals, and abundant aftermarket support have made it a popular platform for drifting, road racing, and street performance modifications. The KA24DE engine, while not as sought-after as the SR20DET, remains a reliable and capable powerplant. Today, well-maintained 240SX Coupes are becoming increasingly rare and valuable, particularly those in original condition. The 240SX’s enduring popularity is a testament to its timeless design and engaging driving experience. Finding a rust-free example is a significant challenge, as many vehicles have succumbed to corrosion over the years. However, for those willing to invest the time and effort, the 240SX Coupe remains a rewarding and enjoyable classic car.
