1998-2001 Nissan Skyline X (R34) 2.0 i 24V (155 Hp)

The Nissan Skyline X (R34) 2.0 i 24V (155 Hp) represents a crucial variant within the tenth generation of the iconic Nissan Skyline lineage, produced from 1998 to 2001. While the R34 generation is most famously associated with its high-performance GT-R variant, the 2.0 i 24V model served as a foundational offering, providing a blend of everyday practicality, renowned Japanese engineering, and the distinctive styling that made the R34 a global phenomenon. Primarily developed for the Japanese Domestic Market (JDM), this sedan variant showcased Nissan’s commitment to delivering a well-rounded and engaging driving experience, even in its more accessible configurations.

Powertrain & Engine Architecture

At the core of the Nissan Skyline X (R34) 2.0 i 24V lies the venerable RB20DE engine. This 2.0-liter (1998 cm3 or 121.93 cubic inches) naturally aspirated inline-six powerplant is a testament to Nissan’s engineering prowess, offering a smooth and refined power delivery characteristic of the RB series. Unlike the more potent turbocharged RB engines found in higher-tier Skylines, the RB20DE was designed for efficiency and reliability in daily driving scenarios.

The engine produces a respectable 155 horsepower at 6400 rpm, translating to a power-per-liter output of 77.6 horsepower per liter. Torque is rated at 137.19 lb.-ft. (186 Nm) peaking at 4400 rpm, providing adequate thrust for city driving and highway cruising. Power is routed to the rear wheels via a precise 5-speed manual transmission, offering an engaging and direct connection between the driver and the machine. This rear-wheel-drive architecture, combined with a well-balanced chassis, contributes to the Skyline’s reputation for enjoyable handling, even in its less powerful forms.

With a compression ratio of 9.5:1 and a DOHC (Double Overhead Camshaft) valvetrain featuring four valves per cylinder, the RB20DE engine is a sophisticated unit for its era. Its multi-port manifold injection system ensures efficient fuel delivery, contributing to its smooth operation. The engine utilizes a cast iron block and an aluminum cylinder head, a common configuration for durability and weight reduction. The RB20DE is known for its relatively simple design, making it easier to maintain and repair compared to more complex turbocharged engines.

Driving Characteristics

The 2.0 i 24V’s driving experience is characterized by smooth, linear power delivery. While it lacks the explosive acceleration of the GT-R, the RB20DE provides sufficient power for confident overtaking and comfortable highway cruising. The 5-speed manual transmission offers precise shifts and allows the driver to fully utilize the engine’s powerband. Compared to the turbocharged RB25DET found in higher trims, the RB20DE feels less stressed and more predictable. The lower power output also results in less torque steer, making it easier to control for less experienced drivers.

The gear ratios are tuned for everyday usability, with a relatively tall fifth gear for fuel efficiency on the highway. The rear-wheel-drive layout provides a balanced feel and allows for predictable handling. While not a dedicated sports car, the 2.0 i 24V offers a rewarding driving experience, particularly for those who appreciate the smoothness and refinement of an inline-six engine.

Equipment & Trim Levels

The Nissan Skyline X (R34) 2.0 i 24V typically came equipped with a respectable level of standard features for its time. Interior upholstery was generally cloth, although optional leather seats were available. The dashboard featured a straightforward layout with analog gauges for speed, tachometer, fuel level, and coolant temperature. Power windows, power door locks, and air conditioning were standard amenities. An AM/FM radio with cassette player was also typically included.

Optional extras included a CD player, upgraded sound system, sunroof, and alloy wheels. Higher trim levels within the 2.0 i 24V range might have featured additional comfort and convenience features, such as automatic climate control and woodgrain interior trim. The overall interior design prioritized functionality and durability, reflecting the car’s intended role as a practical daily driver.

Chassis & Braking

The R34 Skyline X (R34) 2.0 i 24V utilizes a MacPherson strut suspension setup at the front and a multi-link suspension at the rear. This configuration provides a good balance between ride comfort and handling performance. Coil springs and shock absorbers are used at all four corners. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.

Braking duties are handled by ventilated discs at the front and solid discs at the rear. An Anti-lock Braking System (ABS) is standard, enhancing safety and control under hard braking. The hydraulic power-assisted rack and pinion steering system provides precise and communicative feedback to the driver. The chassis is relatively lightweight, contributing to the car’s nimble handling characteristics. The suspension tuning is geared towards comfort and everyday usability, rather than outright performance.

Market Reception & Comparison

Critics generally viewed the Nissan Skyline X (R34) 2.0 i 24V as a competent and well-engineered sedan. It was praised for its smooth engine, comfortable ride, and engaging handling. However, it was often noted that its performance was not as exhilarating as the higher-powered GT-R variants. Fuel economy was considered to be reasonable for a 2.0-liter inline-six engine, typically achieving around 22-26 mpg in mixed driving conditions.

Compared to the turbocharged RB25DET-powered Skylines, the 2.0 i 24V offered improved reliability and lower maintenance costs. The simpler engine design and lower power output reduced stress on the drivetrain components. It also appealed to a wider audience, including those who preferred a more understated and practical vehicle. In terms of reliability, the RB20DE is generally considered to be a robust and durable engine, capable of high mileage with proper maintenance.
