═══════════════════════════════════════════════════════

1987 marked a turning point in Japanese automotive history, ushering in a generation that would forever change the landscape of sports sedans. That's when the model was born Nissan Skyline R31, which not only updated the line, but set new standards for reliability and performance.

You've probably heard that it was with this car that the glory of the legendary RB series engines began, but few people know how revolutionary the suspension and electronics were at that time. If you're considering purchasing a classic Japanese sports car, understanding the specifics of that specific year is critical to a successful transaction.

In this article we will analyze the technical features, operating nuances and hidden problems that the owners of these machines face decades later. You have to find out why turbocharging this model was considered a breakthrough, and how to distinguish an original copy from a fake.

Historical context and emergence of the R31 generation

The R31 generation, which debuted in August 1985 and sold heavily into 1987, replaced the popular R30. Engineers Nissan set an ambitious goal: to create a car that would be both a comfortable sedan for the family and an aggressive racing car.

The external design has become more streamlined and aerodynamic compared to its predecessor, which has reduced the drag coefficient. However, the true revolution occurred under the hood, where the company abandoned the outdated L-series engines in favor of a new line RB-series.

This transition was not just a change in the cylinder block, but a fundamental change in the philosophy of engine design. The new architecture made it possible to implement technologies that were previously used only in professional motorsport, making them accessible to the mass consumer.

The heart of the car: RB series engines

The most important innovation of 1987 was the introduction of the RB series straight-six. Engines RB20E, RB20DE and RB20DET became the basis of the model range, providing an incredible balance between power and reliability. Unlike older engines, they had a cast-iron cylinder block and an aluminum head, which made them virtually indestructible with proper maintenance.

Particular attention should be paid to the turbocharged versions that were installed on the GTS and GTS-X modifications. Turbine Turbo in combination with an ignition control system, it made it possible to develop power unavailable to competitors in this class. Many enthusiasts are still looking for these particular versions, as their potential for improvement is enormous.

For those looking for maximum performance, a limited edition GTS-R was released in 1987. This car was equipped with a shortened cylinder block RB20DET-R with the NAPS-Z system, which provided instant throttle response. It was this engine that became the progenitor of the legendary RB26DETT, which later made the Skyline GT-R famous throughout the world.

It is important to understand that even in the factory version, these engines required high-quality fuel and timely oil changes. Ignoring maintenance regulations can lead to overheating of the turbine or stuck piston rings.

• 🔧 RB20E — naturally aspirated engine with distributed injection, ideal for city driving.
• ⚡ RB20DET - turbocharged version with power up to 190 hp, requires a reinforced transmission.
• 🏁 RB20DET-R - racing version with NAPS-Z system, rare and highly valuable on the market.

Specifications and transmission

The R31 transmission was offered in two main options: a classic manual transmission and a 4-speed automatic. Mechanics, especially 5-speed FS5W71C, was in great demand among drive enthusiasts thanks to its clear switching and reliable synchronizers.

The automatic transmission, although inferior to mechanics in dynamics, ensured a smooth ride and comfort in traffic jams. However, it is worth noting that old torque converters may require replacement or repair at high mileage. All-wheel drive system ATTESA appeared a little later, but the basic versions with rear-wheel drive already demonstrated excellent directional stability.

The suspension was built using a double wishbone design at the front and a multi-link at the rear. This design provided excellent handling, allowing the car to confidently corner even at high speeds. Levers bellows (hydromounts) provided comfort, but require replacement over time due to aging of the rubber.

Параметры двигателя RB20DET-R:
Блок цилиндров: Чугунный
Количество клапанов: 16 (4 на цилиндр)
Степень сжатия: 8.5:1
Мощность: 210 л.с. при 7000 об/мин
Крутящий момент: 250 Нм при 4800 об/мин

Features of the GTS-R model and racing ambitions

The GTS-R modification was created specifically for homologation (admission) in Group A racing. It was not just a marketing ploy, but a full-fledged racing car, adapted for public roads. Exactly 2,000 examples were produced in 1987, making them highly collectible today.

A distinctive feature of the GTS-R was a specific body kit, enlarged wheel arches and unique wheels. Under the hood was an engine with a modified cylinder head, a more efficient turbocharger and an intercooler. Engine management system NAPS-Z allowed the driver to choose engine operating modes, adapting it to different track conditions.

During the inspection, you need to carefully check the VIN code and the compliance of the engine and body numbers with the documentation.

⚠️ Attention: When purchasing a GTS-R, be sure to check for original JDM documents, as many cars have been converted to European or American standards, which reduces their historical value and reliability.

• 🚀 Acceleration 0-100 km/h: only 6.9 seconds, which was a record for 1987.
• 🛣️ Maximum speed: limited electronically, but realistically exceeds 230 km/h.
• ⚖️ Vehicle weight: about 1200 kg, which provided excellent weight distribution.

Operation and typical problems

Despite the reputation of reliable cars, age leaves its mark. The most common problem is corrosion of sills and arches, especially in regions with harsh winters. The chrome on the bumpers and grille is also prone to peeling if not maintained.

In the cooling system, you should pay attention to the condition of the pipes and thermostat. Old rubber hoses can crack, causing the engine to overheat. Also worth checking oxygen sensors and lambda probes, since their failure can lead to increased fuel consumption and loss of power.

The electrics in the R31 are considered one of the most reliable in its class, but the contacts oxidize over time. If you are having trouble starting or the dashboard lights are flashing, check the body ground and the condition of the relay in the mounting block.

⚠️ Attention: Do not buy a car with signs of “garage” suspension repair without a full diagnosis on a lift. Hidden defects in the levers can lead to loss of control at high speed.

Body, interior and ergonomics

The interior of the R31 is made in the style of the 80s: a lot of plastic, buttons and analog instruments. However, the ergonomics are thought out perfectly: all controls are at the driver’s fingertips. Seats with high lateral support provide good support during active driving.

Finishing materials, despite the years, can look decent if the car was not used for taxis or official purposes. A leather-wrapped steering wheel and wood instrument panel inserts are common on richer trim levels such as the GTS. Sound insulation was excellent for its time, but by modern standards it may seem insufficient.

The cosmetic condition of the interior often speaks volumes about how well the car was cared for by the previous owner. If the carpet is worn out and the plastic is scratched, most likely the car has traveled a significant mileage. Pay attention to the condition of the seat belts and their fixing mechanisms.

Features of the air conditioning system

In 1987, air conditioners were not as efficient as they are now. If you are buying a car with climate control, check the tightness of the system and the operation of the compressor, as repairs can be expensive due to the shortage of original parts.

Comparison with competitors and market position

In 1987, the Skyline's main competition was the Toyota Corona Mark II and Honda Vigor. However Nissan favorably differed in its sportier character and the presence of turbo engines. Toyota focused on comfort and reliability, and Honda on high revs, but the Skyline offered a unique balance.

In the sports coupe segment, the R31 competed with the Mazda Cosmo and Mitsubishi Galant VR-4. Thanks to advanced suspension technology and the RB engine, the Skyline often won handling tests. This laid the foundation for winning the World Rally and Endurance Championships.

Today, the price of these cars continues to rise. Original pieces with preserved history become investment assets. However, it is worth considering the cost of spare parts, since many parts are no longer produced and you have to look for them at disassembly sites in Japan.
