In 1987 Nissan Skyline experienced one of the most iconic updates in its history - the debut of a generation R31, which became a bridge between the classic "round headlights" R30 and the revolutionary R32 with the system ATTESA E-TS. This car, released at the height of the era of Japanese technological breakthroughs, combined an aggressive design, advanced series engines for its time RB and unique philosophy rear-wheel drive sports sedan.
Today Skyline R31 - this is not just a rarity, but an object of cult worship among enthusiasts JDM (Japanese Domestic Market). He is appreciated for aluminum RB20DET cylinder head capable of handling up to 500 hp. after tuning without major repairs, for the legendary gearbox FS5R30A, and for that same “analog” drive that cannot be reproduced on modern machines. But before buying, you should know: this car requires not only financial investments, but also deep technical knowledge - especially when it comes to turbocharged versions.
Technical characteristics of the 1987 Nissan Skyline R31
Generation R31 offered with a wide range of engines - from naturally aspirated RB20E to turbocharged RB20DET and even diesel LD28. However, it is RB-series became the calling card of the model. Let's look at the key technical parameters:
| Modification | Engine | Power (hp) | Gearbox | Drive |
|---|---|---|---|---|
| HR31 GTS-R | RB20DET (2.0L Turbo) | 210 | 5-speed manual / 4-speed automatic transmission | Rear |
| HR31 GTS | RB20DE (2.0L Atkinson) | 155 | 5-speed manual / 4-speed automatic transmission | Rear |
| HR31 GX | RB20E (2.0L SOHC) | 130 | 5-speed manual / 4-speed automatic transmission | Rear |
| DR31 (diesel) | LD28 (2.8L) | 95 | 5-speed manual | Rear |
The version deserves special attention GTS-R with motor RB20DET. This engine was equipped with a turbine Garrett T25, intercooler and injection system NICS (Nissan Induction Control System), which made it possible to develop 210 hp at 6400 rpm. For comparison: atmospheric RB20DE with the system Atkinson gave out everything 155 hp, but was incredibly reliable and economical.
Transmission on Skyline R31 was also varied:
- 🔧 5-speed manual transmission FS5R30A — the most desirable option for tuning, can withstand up to
400 Nmtorque. - ⚙️ 4-speed automatic transmission RE4R01A - less reliable, but suitable for everyday use.
- 🔄 Limited slip differential (LSD) - installed on version GTS-R And GTS.
⚠️ Attention: Models with automatic transmission RE4R01A often suffer from overheating when driving aggressively. If you are planning tuning, be sure to install an additional transmission oil cooler!
Design and interior: why the R31 looks futuristic even today
Appearance Nissan Skyline R31 became revolutionary for its time. The car has lost the “round” features of its predecessor R30 and found aerodynamic lines, which later became standard for Japanese sports cars in the 90s. Key design elements:
- 🚗 Hidden headlights - a unique feature that Nissan only used on the R31 and R32.
- 💨 Shark fin ass — a high spoiler and vertical lights gave the car an aggressive look.
- 🔥 Extended arches - on versions GTS-R they were wider by
20 mmon each side.
Inside Skyline R31 combines luxury and sporty spirit. Basic versions received velor upholstery and manually adjustable seats, while top versions GTS-R equipped with:
- 🪑 Sports seats with lateral support (optional Recaro).
- 📉 Digital dashboard with LCD display (on export models).
- 🎛️ Three-spoke steering wheel with leather braid (diameter
360 mm).
Interesting fact: in Japan Skyline R31 offered with option "Auto Climate Control" — one of the first automatic climate control systems in the segment. However, today these electronics often fail due to outdated chips.

Weaknesses and typical problems of Skyline R31
Despite its legendary status, Nissan Skyline R31 has a number design flaws, which every potential owner should know about. The main problems are related to:
- Body corrosion - are especially vulnerable:
- 🚘 Thresholds — rust from the inside, often requiring complete replacement.
- 🚪 Rear wheel arches - accumulate dirt and moisture.
- 🔩 Bumper mounts - the metal becomes thinner to holes.
- RB series engines:
- 🔥 RB20DET - suffers from oil starvation at high speeds (solution: installing an oil pump with R32).
- ⚡ RB20DE - problems with the system Atkinson (valves require adjustment every
40,000 km). - 🛢️ Leaking camshaft seals - a common disease of all RB engines.
- Electronics:
- 💡 Relays and fuses - often burn out due to power surges.
- 📡 Radio antenna — the lifting mechanism breaks down in 90% of cases.
- 🔋 Generator - a weak point on cars with air conditioning.
⚠️ Attention: If you buy Skyline R31 with engine RB20DET, be sure to check the condition Garrett T25 turbines. The service life of the original turbocharger is no more than 150,000 km, after which a replacement or upgrade is required T28.
Another critical issue is suspension. Stock shock absorbers Kayaba nurse no more 80,000 km, and the silent blocks of the rear beam often “die” without warning. Many owners recommend immediately installing kits from Tein or Cusco.
☑️ What to check before buying Skyline R31
Tuning and modifications: how to unlock the potential of the RB20DET
The main reason why Skyline R31 is still in demand - this huge potential for tuning. Engine RB20DET with the right approach can produce 400+ hp without loss of resource. Let's consider the main directions of modifications:
1. Increase engine power
Standard 210 hp - this is just the beginning. To increase power, owners usually go through the following steps:
- 🔥 Stage 1 (300-350 hp):
- Replacing the turbine with Garrett T28 or T3/T4.
- Installing a larger intercooler (for example, from R32).
- ECU firmware (chips from Haltech or Apexi Power FC).
- ⚡ Stage 2 (350-400 hp):
- Forced pistons and connecting rods (sets from JE or Wiseco).
- Improved fuel injectors (
550 ccor740 cc). - Exhaust manifold
4-2-1(for example, from HKS Hi-Power).
2. Transmission and suspension
Stock box FS5R30A withstands up to 400 Nm, but for greater reliability it is recommended:
- 🔧 Install enhanced grip (For example, Nismo or Spec).
- ⚙️ Replace the differential with Cusco LSD 1.5-way for better handling.
- 🏁 Lower suspension on springs Tein S-Tech or BC Racing.
⚠️ Attention: When tuning up to 400+ hp be sure to strengthen the subframe! The stock design is not designed to withstand such loads and may become deformed.
What happens if you don’t change the oil pump on the RB20DET?
At high speeds (6500+ rpm), the standard oil pump does not provide enough pressure, which leads to oil starvation and scoring on the cylinder walls. In critical cases, the engine may seize beyond repair.
How much does a Nissan Skyline R31 cost in 2026?
Prices for Skyline R31 vary greatly depending on condition, modification and market. In Japan, where these cars can still be found in original condition, prices start from ¥800 000 (about $5 500) for the tired version with engine RB20E.
