When they talk about the golden era of the Japanese automobile industry, it is impossible to ignore Nissan Skyline generation R31, and in particular its most powerful modification - GTS-R. This car was the answer to the challenges of the Group A racing world and forever cemented its status as an icon of drifting and circuit racing in the late 80s.
You may not be interested in collectible cars, but even a casual glance at the silhouette R31 GTS-R makes the heart beat faster. This was the moment when engineering Nissan merged with the uncompromising demands of racing regulations to create a car that looked aggressive and performed even tougher.
Birth of a Legend: The History of the GTS-R
In the mid-1980s, Japanese motorsport was booming and Group A regulations required 500 road-going versions to be produced for racing. That's why Nissan created Skyline R31 GTS-R as a special homologation model. This was not just a marketing ploy, but a necessity to win the JTCC championship.
Development took less than a year, and the engineers set themselves the task of creating a coupe that was lightweight, agile and incredibly powerful. Unlike standard versions, GTS-R received unique aerodynamics, including a characteristic rear spoiler and a front bumper with a powerful air intake, which became the calling card of the model.
You have to understand that production was strictly limited. Only 500 examples were produced, and each one bore a unique serial number on a metal plaque in the interior. It is because of this strict 500 unit limit that the GTS-R is one of the most desirable and expensive models for collectors today..
Heart of the Legend: RB20DET-R Engine
The most important aspect for which this car was purchased was the engine. Under the hood Nissan Skyline R31 GTS-R the famous inline six-cylinder engine was hiding RB20DET-R. It was a twin-turbo version, which was an advanced solution for production cars.
System Sequential Twin Turbo used one small turbo for instant response at low revs and one large one for maximum power at the top of the range. This made it possible to avoid the “turbo lag” characteristic of that time, making acceleration smooth and continuous.
Despite the modest nameplate data of 210 hp, the real potential of the engine was much higher. With proper adjustment and replacement of nozzles, this unit can withstand pressure up to 250-280 hp. without major intervention in the cylinder block.

ECUwas adapted specifically to work with a twin turbine. - 💨 Turbines HKS (or original Hitachi) worked in tandem, shifting at 3500 rpm.
- ⚙️ Cylinder block RB20 It has a cast iron sleeve, which makes it incredibly reliable.
Body and chassis design
To compensate for the weight of the engine and turbines, engineers Nissan took radical measures to lighten the body. The roof, hood and trunk were made of aluminum, which reduced the total weight of the car to 1150 kg. This is critical for dynamics and handling.
Chassis GTS-R was tuned much tougher than usual SKYLINE. Rear suspension type Multi-Link provided excellent stability on the trajectory, and the front strut MacPherson with reinforced levers to withstand high loads during aggressive driving.
You need to pay attention to the rims. Original wheels 15 inches with tires 195/50 R15 provided excellent grip, but today they are difficult to find in perfect condition. Many owners replace them with more modern alloy wheels, maintaining the original spoke design.
⚠️ Attention: Aluminum body panels on R31 GTS-R are susceptible to corrosion at the mounting points, especially if the car has passed through regions with salty roads in winter. Inspect the sills and arches before purchasing.
The interior was purely utilitarian, but functional. Seats Bride or Nissan with high lateral support were standard for this version. The instrument panel included a tachometer with a red zone of up to 7000 rpm, which emphasized the sporty character of the car.
Specifications and comparison
For visual comparison GTS-R with other versions SKYLINE R31, we have prepared a table of the main parameters. This will help you understand exactly why this model stood out from its peers.
| Model | Engine | Power | Drive | Weight |
|---|---|---|---|---|
| Skyline R31 GTS | RB20E (atmo) | 155 hp | Rear | 1250 kg |
| Skyline R31 GTS-4 | RB20DET | 190 hp | Full | 1320 kg |
| Skyline R31 GTS-R | RB20DET-R | 210 hp | Rear | 1150 kg |
| Skyline R32 GT-R | RB26DETT | 280 hp | Full | 1430 kg |
As can be seen from the table, GTS-R was lighter and more powerful than usual GTS, but at the same time he was inferior to the future GT-R (R32) in absolute power. However, its advantage lay in its weight-to-power ratio, which made it very exciting to drive.

Features of service and tuning
Possession Nissan Skyline R31 GTS-R today is not only the pleasure of driving, but also a certain responsibility. Spare parts for this model are not easy to find, since it was not officially supplied to many countries, including the USA and Europe in large quantities.
The first step is to check the cooling system. The twin-turbo design generates a lot of heat, and old radiators often fail to cope with the loads in traffic jams. Installing a more efficient intercooler is one of the first and most necessary modifications.
- 🔧 Replace all rubber pipes with silicone ones to improve reliability.
- 🛢️ Use only high quality synthetic oil with approval
5W-40or10W-40. - 🔋 Regularly check the condition of the ignition coils, as they are subject to wear from high temperatures.
If you are planning tuning, then the most popular direction is replacing the exhaust system and reflashing ECU. This will unlock the potential of the turbines and improve the exhaust sound, which RB20DET-R initially very musical.
⚠️ Attention: When tuning, do not forget about the transmission. Standard 5-speed manual transmission FS5W71C has weak synchronizers and is not designed for long-term operation with power above 250 hp.
☑️ Checklist before purchasing
What is HICAS?|HICAS (High Capacity Active Steering) is an active rear-wheel steering system that was used on more expensive versions of the Skyline. This was omitted from the GTS-R, making the car more predictable and easier to drive for racing, but less nimble at low speeds compared to the all-wheel drive GTS-4.-->
Collectible value and market
