The 1986 Nissan Skyline 2D Sport Coupe GTS-X Twincam 24V Turbo is a definitive machine of the R31 generation. It represents Nissan’s pivot toward a more technologically advanced and luxurious performance identity. The R31, launched in 1985, initially arrived only in sedan and hardtop forms. Therefore, the introduction of the two-door coupé body in May 1986 was a welcome return for enthusiasts. This specific GTS-X model became the range-topping twin-cam turbo coupé. It immediately established the R31’s credentials as a serious performance car, especially within the fiercely competitive Japanese market.
The Return of the Coupé and the R31 Lineage
For many, the coupé body style is essential to the Skyline nameplate’s heritage. The 1986 Nissan Skyline 2D Sport Coupe GTS-X Twincam 24V Turbo restored this crucial format to the line-up. It featured a more aggressive stance and revised bodywork compared to the standard sedan. This inclusion solidified the R31’s image. Furthermore, it created the platform necessary for the later development of the legendary GTS-R homologation special. The GTS-X played a vital role in keeping the performance flame alive before the R32’s arrival.
Twincam 24V Technology
The core of this model’s complex name lies in its engine technology: “Twincam 24V.” This signifies a dual overhead camshaft (DOHC) setup with four valves per cylinder. This was a significant upgrade over the single overhead cam (SOHC) engines found in lesser R31 models. The DOHC head allowed the engine to breathe far more efficiently at higher RPMs. Consequently, it delivered the high-revving performance character that enthusiasts expected from a true sports coupé. This configuration clearly demonstrated Nissan’s engineering commitment.
Advanced Chassis and Handling Systems
The R31 generation introduced one of Nissan’s most famous chassis innovations: HICAS. High Capacity Actively Controlled Steering was an early four-wheel steering system. This technology was designed to subtly turn the rear wheels to enhance the car’s stability and agility. The GTS-X models were typically equipped with this HICAS system as standard equipment. This further improved the car’s cornering abilities, especially during high-speed maneuvers. This focus on handling proved that the R31 GTS-X was a comprehensive performance package. The car was engineered to handle its turbo power with precision.
A Ceramic Turbocharger Boost
Another technical highlight of this era was the use of a ceramic turbine wheel in the turbocharger. This material was lighter than traditional metal alloys. The ceramic turbo spool allowed for a significant reduction in rotational inertia. Consequently, this engineering choice substantially minimized turbo lag. This gave the GTS-X a more immediate and responsive throttle feel. This focus on minimizing lag improved the overall driving experience. It ensured the car felt quick and eager, even at lower engine speeds.
Power, Engine Specs, and Performance
The 1986 Nissan Skyline 2D Sport Coupe GTS-X Twincam 24V Turbo was powered by the 2.0-liter RB20DET engine. This was a dual overhead cam, turbocharged, inline-six. This potent engine produced 132 kW, translating to 180 PS or approximately 177 horsepower, at 6400 rpm. The maximum torque was a strong 225 Nm, peaking at 3600 rpm. This power was sent to the rear wheels via a five-speed manual transmission or an automatic option. The GTS-X boasted excellent top speed and acceleration figures for its class. It offered genuine sports car performance in a coupé body.
The Bridge to the GT-R Legacy
The R31 GTS-X serves as a critical evolutionary link in the Skyline bloodline. It was a clear precursor to the legendary R32 GT-R that followed. The engineering philosophy and key components, particularly the RB engine and advanced chassis tech, were refined here. The GTS-X effectively set the stage for the return of the full GT-R badge. It proved that a sophisticated, luxurious, and technically advanced Skyline could also dominate the performance conversation. Enthusiasts recognize its vital contribution to the brand’s high-performance identity.
The 1986 Nissan Skyline 2D Sport Coupe GTS-X Twincam 24V Turbo stands as a landmark in Nissan’s history. It successfully merged luxury appointments with cutting-edge DOHC turbo performance. With its powerful RB20DET engine and innovative HICAS, the GTS-X proved the Skyline could be a world-class sports coupé. Its engineering set the foundation for future generations. The GTS-X is a revered icon, celebrated for its technical brilliance and pivotal role in the Skyline story.
