The eighth generation Nissan Skyline, known around the world as the R31, marked a turning point in the history of the Japanese automobile industry. It was this model that marked the transition from simple carburetor engines to complex injection systems and the introduction of the legendary in-line six series RB. For many enthusiasts, the R31 is considered the “golden mean”, where classic design was combined with advanced technologies for the late 80s.

If you are considering purchasing this car today, it is important to understand that Nissan Skyline R31 is not just an old foreign car, but a cult object with a unique history. It became the platform for the creation of the first mass-produced turbo engines in the Skyline family and proved that reliability can go hand in hand with high performance.

Historical context and body design

Presentation Nissan Skyline R31 took place in 1985, and the model immediately attracted attention with its understated but aggressive aesthetics. Designers abandoned the overly rounded shapes of its predecessor, moving towards more angular lines that became the harbingers of the style of the 90s. The front optics deserve special attention: the famous “square” headlights, which are often called “robot eyes,” have become the hallmark of the generation.

Body styles ranged from a utilitarian sedan to a sports coupe and even a convertible. For owners of cars with bodies Hardtop It was especially lucky: the lack of a center pillar created a feeling of spaciousness and lightness, which was rare for Japanese sedans of that time. The interior has also undergone changes: the dashboard has become more informative, and the ergonomics have become more convenient for long trips.

It is important to note that it was in this generation Skyline gained access to 4WD technologies, which was a revolutionary step for a rear-wheel drive sedan. System HICAS (High Capacity Active Steering) allowed the rear wheels to turn at small angles, significantly improving high-speed maneuverability and cornering stability.

⚠️ Attention: When inspecting the body of the R31, pay special attention to the sill and rear wheel arches. Corrosion in these areas is the most common problem and can render a vehicle unsuitable for restoration without significant expense.

The interior design was made in a strict style typical of Japanese business culture of the 80s. However, even in the basic trim levels one could find options such as electric windows and climate control, which was a luxury for that time. Sports versions received leather steering wheels and firmer seats, emphasizing the sporty nature of the car.

Engines: The era of the legendary RB

With my heart Nissan Skyline R31 became an inline six-cylinder engine RB20E, which replaced the outdated FJ series. This was the first mass-produced engine with electronic fuel injection in the Skyline family. The power was about 110-125 hp, which for a heavy sedan was quite enough for comfortable city driving. However, the real breakthrough was the appearance of turbocharged versions.

Version RB20DET turbocharged has become a legend. From the factory it produced 185 hp, but thanks to the robust block design and cylinder head, this engine easily tolerated the installation of more powerful turbines. It was on the basis of the R31 that the foundations of Japanese street racing began to take shape, where tuning RB engines became the de facto standard.

A limited edition was released for the most demanding customers. GTS-R, equipped with a motor RB20DET-R. This unit had a modified intake system, reinforced pistons and a Garrett T25 turbine, which made it possible to develop up to 210 hp. The RB20DET-R was the first Japanese production engine designed specifically for Group A racing. Its production was limited to just 5,000 examples, making these cars now extremely valuable collector's items.

  • 🔥 RB20E - naturally aspirated engine for a quiet ride, highly reliable and easy to maintain.
  • 🚀 RB20DET — a turbocharged version with excellent opportunities for tuning and modifications.
  • 🏆 RB20DET-R - a rare sports version with reinforced components and high power.

In addition to the RB series, the line also included less powerful 4-cylinder engines of the CA series, which were installed on the basic configurations. They're economical, but don't deliver the emotional impact that a straight-six promises. The choice of engine directly depends on your goals: daily use or participation in drift seasons.

⚠️ Attention: Turbocharged versions of the R31 require high-quality oil and regular turbine replacement. Ignoring service intervals can cause the turbocharger bearings to seize and leak oil into the engine.

Transmission and Suspension: Handling and Dynamics

The R31 transmission range offered both manual gearboxes and classic torque converter automatics. Manual transmission 5-speed had clear inclusions and a short stroke, which made driving sporty. Automatic transmissions, although reliable, often suffered from hesitation under hard acceleration, which was not in keeping with the spirit of the model.

The car's suspension has been designed with an emphasis on comfort without sacrificing handling. The front type design was used McPherson, and at the rear there is a multi-link design. This ensured excellent wheel performance on uneven surfaces and high stability on the track. The presence of the HICAS (active rear-wheel steering) system on the top versions made the car incredibly responsive when cornering.

Many owners modify the suspension by installing coilovers or stiffer anti-roll bars. This allows you to turn a comfortable sedan into a track tool without losing its everyday practicality. It is important to choose the right settings so as not to overload the body.

The braking system on the R31 was adequate for its time, but as tuning power increases, it requires upgrading. Standard calipers and discs may not be able to cope with prolonged braking at high speeds. It is recommended to install larger discs and calipers from more powerful models, for example, from Stagea or 350Z.

  • 🛑 Front brakes — ventilated discs, effective at standard power.
  • 🔧 Modernization — replacing the calipers with 4-piston ones will significantly improve braking.
  • 🛣️ Stabilizers — installation of more rigid elements will reduce roll in corners.
