1996 Nissan 240sx Se Technical Specifications Review

The 1996 Nissan 240SX SE remains a highly sought-after vehicle, not just for its iconic status in drifting and performance tuning, but also for its fundamentally sound engineering. This review delves into the technical specifications of the SE model, providing an in-depth analysis suitable for both curious readers and amateur engineers eager to understand its inner workings.

Engine & Drivetrain

The heart of the 1996 240SX SE is the KA24DE engine, a 2.4-liter (2389cc) inline-four cylinder, dual overhead cam (DOHC) engine. This powerplant, while not as technologically advanced as some of its competitors at the time, offered a robust and reliable foundation for performance enhancement.

Engine Specifications:

Engine Code: KA24DE
Configuration: Inline-4, DOHC, 16-valve
Displacement: 2.4 liters (2389cc)
Bore x Stroke: 89.0 mm x 96.0 mm (3.50 in x 3.78 in)
Compression Ratio: 9.5:1
Fuel Delivery: Electronic Fuel Injection (EFI)
Horsepower: 155 hp @ 5600 rpm
Torque: 160 lb-ft @ 4400 rpm

The KA24DE's relatively long stroke contributes to its strong low-end torque, making it a popular choice for drivers who appreciate immediate throttle response. The cast-iron block provides excellent durability, while the aluminum alloy cylinder head helps reduce weight.

The engine management system is a key component. It precisely meters fuel and controls ignition timing based on sensor inputs like manifold absolute pressure (MAP), throttle position, engine speed, and coolant temperature. This system ensures optimal performance and fuel efficiency under various driving conditions.

Two transmission options were available: a 5-speed manual and a 4-speed automatic. The 5-speed manual, often preferred by enthusiasts, offers a direct connection to the engine and allows for greater control over gear selection. The gear ratios are designed to maximize the engine's torque output. The automatic transmission, while offering convenience, sacrifices some of the performance potential of the manual. It features electronically controlled shifting for smoother transitions. Regardless of the transmission, power is delivered to the rear wheels via a limited-slip differential (LSD) on SE models, which significantly improves traction and handling, especially in slippery conditions or during aggressive cornering. The LSD is a crucial factor in the 240SX's appeal for drifting.

Chassis & Suspension

The 240SX's chassis is a unibody construction, providing a good balance of rigidity and weight. The suspension system is a four-wheel independent design, featuring MacPherson struts in the front and a multi-link setup in the rear. This setup offers excellent handling characteristics and helps to maintain stability during cornering.

Suspension Specifications:

Front Suspension: MacPherson struts with coil springs and stabilizer bar
Rear Suspension: Multi-link independent with coil springs and stabilizer bar

The MacPherson strut design in the front is relatively simple and cost-effective, but it can be prone to bump steer if not properly maintained or modified. The multi-link rear suspension provides more precise control over wheel movement, improving grip and handling. The stabilizer bars, both front and rear, help to reduce body roll during cornering, further enhancing stability.

The SE model benefits from slightly stiffer springs and dampers compared to the base model, resulting in a more responsive and controlled ride. These improvements contribute to the car's sporty handling characteristics.

Braking System:

Front Brakes: Ventilated discs
Rear Brakes: Solid discs
Anti-lock Braking System (ABS): Optional

The braking system consists of ventilated discs in the front and solid discs in the rear, providing adequate stopping power for everyday driving. An optional ABS system was available, which helps to prevent wheel lockup during hard braking, improving safety and control. However, many enthusiasts disable the ABS system for drifting purposes, preferring the ability to lock the rear wheels intentionally.

Exterior & Interior

The exterior design of the 1996 240SX SE is characterized by its sleek, aerodynamic lines and pop-up headlights. The car's low stance and wide track give it a sporty and aggressive appearance. The SE model typically features a rear spoiler and side skirts, further enhancing its visual appeal.

Inside, the 240SX SE offers a driver-focused cockpit with a simple and functional layout. The seats are supportive and comfortable, providing adequate bolstering for spirited driving. The instrument panel is easy to read, with clearly marked gauges for speed, RPM, fuel level, and coolant temperature. While not luxurious, the interior is well-built and durable, with quality materials used throughout.

Dimensions & Weight:

Wheelbase: 97.4 inches
Length: 176.6 inches
Width: 66.5 inches
Height: 52.0 inches
Curb Weight: Approximately 2700-2800 lbs (depending on options)

The 240SX's relatively light weight is a significant factor in its agility and performance. Combined with its well-balanced chassis and responsive engine, this makes it a fun and engaging car to drive.

Electrical System

The electrical system of the 1996 240SX SE is a standard 12-volt system. It includes a battery, alternator, starter motor, ignition system, lighting system, and various sensors and actuators. The engine control unit (ECU) is the brain of the electrical system, controlling fuel delivery, ignition timing, and other engine functions.

The wiring harness is relatively simple and straightforward, making it relatively easy to diagnose and repair electrical problems. However, due to the age of the vehicle, it's common to encounter issues with corroded connectors and damaged wiring.

Modifications & Tuning

The 1996 Nissan 240SX SE is a highly popular platform for modifications and tuning. Its robust engine, well-balanced chassis, and readily available aftermarket parts make it an ideal choice for enthusiasts looking to improve performance and handling.

Common modifications include:

Engine Upgrades: Turbocharging, supercharging, camshaft upgrades, intake and exhaust modifications
Suspension Upgrades: Lowering springs, adjustable coilovers, upgraded sway bars, aftermarket bushings
Brake Upgrades: Larger rotors, performance brake pads, stainless steel brake lines
Drivetrain Upgrades: Upgraded clutch, lightweight flywheel, stronger axles

Many enthusiasts also swap the KA24DE engine for more powerful engines, such as the SR20DET or even V8 engines. These swaps require significant modifications to the engine bay and drivetrain, but can result in a significant increase in performance.

It's important to note that any modifications should be done carefully and professionally to ensure safety and reliability. Proper tuning is also essential to maximize the performance benefits of any modifications.

Conclusion

The 1996 Nissan 240SX SE remains a relevant and desirable vehicle due to its inherent qualities. Its robust engine, well-engineered chassis, and responsive handling make it a rewarding car to drive. While it may not be the most technologically advanced car on the road today, its simplicity and durability have made it a favorite among enthusiasts for decades. Its potential for modification and tuning further enhances its appeal, allowing owners to personalize their cars to suit their individual needs and preferences. The 240SX SE is more than just a car; it's a platform for self-expression and a testament to the enduring power of good engineering.
