This model is especially famous for its participation in films, games and racing series, which made it legendary far beyond Japan.

In this article we will look at all the key technical specifications Skyline R34, including engines, transmission, suspension and electronics. You will find out how the versions differ GT-R, GT-T And 25GTwhat innovations did you use? Nissan in this model, and why it still remains one of the most sought after on the secondary market. If you are planning a purchase or are simply interested in the history of the Japanese automobile industry, this material is for you.

Nissan Skyline R34 engines: from naturally aspirated to turbo monsters

Heart Skyline R34 - this is a line of engines RB, which were famous for their reliability and potential for tuning. Basic versions were equipped with naturally aspirated engines, and top versions were equipped with legendary turbocharged units capable of delivering more 300 hp from the factory. Let's consider all the options in more detail.

The most famous engine is, of course, RB26DETT, which was installed on GT-R. This one 2.6-liter inline six-cylinder twin-turbocharged engine developed 280 hp by Japanese standards (actually about 320 hp) and had the potential for serious tuning. I wonder what Nissan artificially lowered official power figures due to a "gentleman's agreement" between Japanese automakers.

• 🔥 RB26DETT — 2.6 l, twin-turbo, 280+ hp (actually ~320 hp), installed on GT-R
• 💨 RB25DET — 2.5 l, single-turbo, 250–280 hp, versions GT-T And GT-X
• 🚗 RB20DE — 2.0 l, naturally aspirated, 155 hp, basic configuration 25GT
• ⚡ RB25DE — 2.5 l, naturally aspirated, 200 hp, versions 25GT Four And 25GT-X

Feature RB26DETT there was a system NICS (Nissan Induction Control System), which optimized the air supply to the cylinders, as well as durable closed cylinder deckallowing to withstand high loads. Turbines Garrett T25 as standard could be replaced with more efficient ones T28 or T3/T4 in tuned versions.

⚠️ Attention: Upon purchase Skyline R34 with engine RB26DETT Be sure to check the condition of the turbines and oil pump. These components often wear out due to aggressive use, and their replacement costs a tidy sum.

Transmission: from automatic to the legendary Getrag

Skyline R34 offered with three types of transmissions: 5-speed manual transmission, Getrag 6-speed manual transmission (only for GT-R) and 4-speed automatic. Each of them had its own characteristics and was intended for different driving styles.

The most desired was Getrag 6-speed manual, which was installed exclusively on GT-R. This box was renowned for its durability and precise shifting, making it ideal for the race track. I wonder what Nissan used double disc clutch paired with this gearbox for better torque transmission.

Transmission type	Models	Features	Max. torque
5-speed manual	25GT, GT-T	Standard mechanics, reliable, but less sporty	350 Nm
6-speed Getrag	GT-R	Reinforced gearbox with short gears, double-disc clutch	400+ Nm
4-automatic	25GT, GT-X	Classic torque converter, less dynamic	300 Nm

The automatic transmission, although considered less sporty, had its advantages: smooth operation and reliability. However, enthusiasts preferred the manual, especially given that Skyline R34 often used for drifting and drag racing. It's important to note that synchronizers Mechanical boxes wear out over time, so when purchasing a used one, it is worth checking their condition.

Suspension and handling: ATTESA E-TS and Super-HICAS technologies

One of the key features Skyline R34 was his suspension, combining comfort and sporty handling. Nissan used an independent multi-link suspension on all wheels, which provided excellent directional stability and responsiveness when cornering.

But the real "trick" GT-R became an all-wheel drive system ATTESA E-TS (Advanced Total Traction Engineering System for All-Terrain). This electronic system distributed torque between the axles depending on driving conditions, making the car extremely stable at high speeds and in corners. In addition, Skyline R34 GT-R equipped with a system Super-HICAS — active rear suspension control, which improved handling at the limit.

• 🔧 Front suspension - independent, multi-link, with springs and shock absorbers Bilstein (in sports versions)
• 🔧 Rear suspension - independent, multi-link, with system Super-HICAS (only GT-R)
• 🎯 ATTESA E-TS — electronic all-wheel drive with a multi-plate clutch in the transfer case
• 🛠️ Brakes - ventilated discs Brembo front (320 mm) and rear (297 mm) on GT-R

System Super-HICAS allowed the rear wheels to steer slightly when cornering, which reduced oversteer and made the car more predictable. However, this system also had a disadvantage: over time, the hydraulic hoses and pump wore out, requiring expensive repairs. Many owners have disabled HICAS when tuning, replacing it with rigid rods.

Dimensions, weight and aerodynamics: why the R34 is so stable

Skyline R34 It had compact dimensions by modern standards, which made it light and maneuverable. Body length was 4.67 meters, width - 1.78 meters, and the height is only 1.36 meters. Low center of gravity and even weight distribution (approx. 55:45 front and rear) provided excellent stability.

The weight of the car varied depending on the configuration:

• 🏋️ 25GT (aspirated) - ~1,450 kg
• 🏋️ GT-T (turbo) — ~1,520 kg
• 🏋️ GT-R — ~1,560 kg (due to all-wheel drive and reinforced parts)

Aerodynamics Skyline R34 was thought out to the smallest detail. Drag coefficient (Cx) was 0,30, which was an excellent indicator for the late 90s. Spoiler on the trunk lid (in version GT-R) not only gave an aggressive look, but also created downforce at high speeds. In addition, the front bumper had special air intakes for cooling brakes and radiator.

⚠️ Attention: When installing non-original body kits or spoilers, the aerodynamic characteristics may deteriorate, which will lead to a decrease in stability at speeds above 200 km/h. Always check the certification of tuning parts.

Electronics and on-board computer: what the R34 can do

Skyline R34 was equipped with advanced electronic systems for its time. In particular, GT-R had multifunctional on-board computer, which displayed data on boost pressure, oil temperature, lap time and even acceleration in G-forces. This information was displayed on digital display in the center console.

In addition, the car was equipped with:

• 📊 Traction Control System (TCS) — prevented wheel slipping
• 🔄 Adaptive suspension (optional) - automatically adjusted the stiffness of shock absorbers
• 🎵 Bose audio system - premium sound with 8 speakers
• 🔐 Immobilizer Nissan NATS - protection against theft

One of the unique features GT-R was R-Mode, which activated more aggressive engine and transmission settings. When it was turned on, a red light on the dashboard came on, and the throttle response became instantaneous. This feature was especially useful on the track or when overtaking.

How to activate hidden diagnostic mode?

To enter the service menu of the on-board computer, hold down the button TRIP and turn the ignition key to position ON. In the menu you can check engine errors, sensor status and even reset the service interval.

Options and features of different versions

Nissan Skyline R34 was produced in several trim levels, each of which had its own unique features. The most popular were GT-R, GT-T And 25GT, but there were other options, for example, GT-X with all-wheel drive or rare 40th Anniversary Edition.

Model	Engine	Drive	Features
GT-R	RB26DETT, 2.6 l, twin-turbo	ATTESA E-TS (full)	6-speed Getrag, Super-HICAS, reinforced brakes
GT-T	RB25DET, 2.5 l, single-turbo	Rear or full (optional)	5-speed manual or 4-speed automatic transmission, sports suspension
25GT	RB20DE or RB25DE, atmospheric	Rear	More comfortable setting, fewer sport options
GT-X	RB25DET or RB25DE	ATTESA (full)	All-wheel drive version without turbine (rare)

The most desirable for collectors is GT-R V-Spec II Nür - limited edition (about 1,000 copies), released in honor of victories Skyline on Nürburgring. This model had improved aerodynamics, a stiffer suspension and a unique color scheme. Midnight Purple II, which changed color over time.

Weaknesses and what to check when purchasing

Despite its legendary status, Skyline R34 has several typical problems, which are worth knowing before purchasing. Many of them are related to the age of the car and the specifics of the Japanese roads for which it was designed.

Main weaknesses:

• 🔥 Turbines - resource of original Garrett T25 is about 100,000 km, after which replacement is required
• 🛢️ Oil pump - often wears out at high speeds, leading to a drop in oil pressure
• 🔋 Electronics - problems with sensors (especially MAF And knock sensor)
• 🩹 Body — rust in arches, sills and under window seals

When inspecting a used vehicle, be sure to check:

1. Condition turbines (is there any play, oil drips)
2. Pressure oils at idle and high speeds
3. Job ATTESA (are there any errors in the all-wheel drive system)
4. Condition clutch (especially on GT-R with double disc clutch)

⚠️ Attention: Many Skyline R34 on the secondary market they have twisted mileage. Check the car's history through Japanese auctions (eg. USS or Beforward) and pay attention to the condition of the steering wheel, pedals and seats - they show real mileage.

FAQ: Frequently asked questions about the Nissan Skyline R34

🔧 Which engine is better for tuning: RB25DET or RB26DETT?

RB26DETT has more potential thanks to a durable block and twin turbocharging, but it is more expensive to maintain. RB25DET cheaper and easier to modify, especially if you are planning a single-turbo conversion. For beginning tuners, it is often recommended to start with RB25.

💰 How much does Skyline R34 cost in 2026?

Prices vary greatly depending on condition and equipment:

• 25GT (aspirated) - from 15 000$ (in poor condition) up to 30 000$ (clean copy)
• GT-T - from 25 000$ to 50 000$
• GT-R - from 80 000$ to 200 000+$ (for rare versions like Nür)

🚗 Is it possible to legally import Skyline R34 into Russia?

Yes, but with reservations. From 2023, new rules for customs clearance of cars older than 5 years will apply in Russia. Skyline R34 (1998–2002) falls under the “retro car” category, which simplifies the procedure, but requires registration vehicle type approval (VTA). It is also necessary to check compliance with environmental standards (the exhaust system often requires modifications).

⚡ What oil should I put in RB26DETT?

Recommended to use semi-synthetic or fully synthetic oil with viscosity 10W-40 or 5W-40 (for cold climates). Popular brands among owners:

• Motul 300V (for extreme loads)
• Liqui Moly Leichtlauf (good price/quality balance)
• Nissan Original Oil (if you want the original)

Important: change oil every 5,000–7,000 km, since turbocharged engines RB sensitive to the quality of the lubricant.

🎯 How to distinguish an original GT-R from a replica?

There are many fakes on the market, where GT-T or 25GT remodeled for GT-R. Signs of the original:

• Availability "GT-R" badge on the rear door and steering wheel
• VIN code should start with BNR34 (for GT-R)
• Getrag 6-speed gearbox (on replicas often 5-mortar)
• ATTESA E-TS (checked by test drive on a slippery surface)
• Twin turbines (on RB26DETT there are two of them, on RB25DET - one)

It is also worth checking the documents: original GT-R must have Japanese export certificate indicating the model BNR34.
