1999 Nissan Skyline R34: JDM Legend with RB26DETT and GT-R

Released in 1999 Nissan Skyline R34 became the last generation of the legendary series, which was produced until 2002. This model is an iconic symbol of Japanese engineering, combining aggressive design, advanced technology and a legendary engine. RB26DETT. Versions are especially appreciated GT-R, which thanks to the all-wheel drive system ATTESA E-TS Pro and active rear differential Super HICAS still dominate the track and drift competitions.

1999 was a turning point: Nissan introduced an updated version with improved aerodynamics, modified headlights and a new engine management system. However, even basic modifications Skyline R34 (For example, 25GT-T with motor RB25DET Neo) remain in demand among enthusiasts. In this article we will analyze technical features, typical problems, operating nuances and current prices on the 2026 market - including rare versions like GT-R V-Spec II Nür.

Technical characteristics of the 1999 Nissan Skyline R34

The 1999 model range included several modifications, differing in engines, gearboxes and suspension settings. Basic versions were equipped with naturally aspirated engines RB20DE (2.0 l, 155 hp) and RB25DE Neo (2.5 l, 200 hp), but the turbocharged options are of real interest:

• 🔥 25GT-T: RB25DET Neo (2.5 l, turbine Garrett T28, 280 hp according to Japanese standards).
• 🏁 GT-R: RB26DETT (2.6 l, twin turbo IHI RHF55B, 280 hp "gentleman's agreement", realistically ~320–330 hp).
• ⚡ GT-R V-Spec: same RB26DETT, but with a stronger clutch, an improved cooling system and a limited slip differential.

All GT-R equipped with a 6-speed manual transmission Getrag 260, while other versions could be equipped with a 5-speed manual or 4-speed automatic RE4R01A. Drive - all-wheel drive (ATTESA E-TS) or rear (for base models). Suspension - multi-link rear and struts MacPherson front, with the option of installing an active steering system Super HICAS.

Modification	Engine	Power (hp)	Box	Drive
25GT	RB25DE Neo	200	5MT/4AT	Rear
25GT-T	RB25DET Neo	280	5MT/4AT	Rear/Full
GT-R	RB26DETT	280 (actually ~330)	6MT	Full (ATTESA)
GT-R V-Spec	RB26DETT	280 (actually ~330)	6MT	Full (ATTESA Pro)

Weaknesses and typical problems

Despite its legendary status, Skyline R34 has a number of “diseases” that any potential owner should be aware of. The main problem is corrosion. Body panels, especially wheel arches, sills and underbody, actively rust even with slight contact with moisture. The second "Achilles heel" - turbines: original Garrett T28 (for 25GT-T) and IHI RHF55B (for GT-R) wear out by 150–200 thousand km.

Other common faults:

• ⚠️ Oil pump: on RB26DETT often fails after 100 thousand km, which leads to oil starvation and scuffing on the crankshaft.
• 🔧 Clutch: on GT-R it breaks down already at 50–80 thousand km (especially if the previous owner was involved in drifting).
• 🔥 Ignition coils: they break at high speeds, which leads to misfires.
• 💧 Seal leaks: crankshaft, camshafts and rear oil seal - a standard problem for everyone Skyline with mileage.

⚠️ Attention: If upon purchase GT-R The seller claims that the engine has "never been opened", which is cause for skepticism. Most RB26DETT by 2026 they have already been renovated - check the documents for the capital!

Electronics also do not last forever: sensors often fail MAF, AFM and control unit ECU. Systems are especially vulnerable ATTESA And HICAS — their repair costs 100–300 thousand rubles. One more nuance: original turbochargers on GT-R designed for 0.8–1.0 bar of boost. Exceeding this value without upgrading the fuel system and intercooler leads to detonation and engine destruction.

Prices for 1999 Nissan Skyline R34 in 2026

Cost Skyline R34 on the secondary market varies from 800 thousand to 15 million rubles - depending on modification, mileage and history. Basic 25GT with naturally aspirated engines can be found for 1–1.5 million rubles, but their purchase is rarely justified: the demand for them is low, and spare parts cost almost as much as for GT-R. Turbocharged 25GT-T are estimated at 1.8–3.5 million rubles - the key factor here is the condition of the turbine and engine.

Prices for GT-R start at 4 million rubles for “tired” copies with a mileage of under 200 thousand km. Versions V-Spec And V-Spec II Nür (with factory body kit and improved suspension) cost 8–15 million rubles. Cars with mileage less than 50 thousand km stand apart - their owners ask for 20–30 million, but such offers are almost always fraudulent (twisted mileage or “assembled” cars from several donors).

Modification	Condition	Mileage (thousand km)	Price (2026), RUB million
25GT	Satisfactory	150–200	1.0–1.5
25GT-T	good	80–120	2.5–3.5
GT-R	Good (after capital)	100–150	5.0–7.0
GT-R V-Spec II Nür	Excellent (collectible)	<50	12.0–15.0

⚠️ Attention: There are a lot of "gray" ones on the market Skyline R34smuggled from Japan. Check history via JDM Export or CarVertical — a car without official documents cannot be registered in Russia!

Tuning and modifications: what can be done with the R34

Skyline R34 is one of the most tuning-friendly platforms in the world. Even basic 25GT-T with motor RB25DET Neo capable of producing 400+ hp. after installing the turbine Garrett GT2860, fuel injectors Nismo 550cc and firmware ECU (For example, Haltech Elite or Link G4+). However, the real potential comes from GT-R:

• 💨 Stage 1 (400–450 hp): Replacement of turbines with Tomei M82, intercooler GReddy, exhaust 3.5" without catcollector, firmware.
• 🔥 Stage 2 (500–600 hp): Forged pistons JE, connecting rods Eagle, turbines Garrett GT3076, fuel pump Walbro 450.
• ⚡ Stage 3 (700+ hp): Block RB30, head Tomei 264, turbines BorgWarner EFR 9174, box OS Giken.

The suspension also requires attention: standard shock absorbers Bilstein on GT-R can withstand up to 100 thousand km, after which it is better to replace them with Tein Super Street or Ohlin DFV. Kits are popular for drifting Wisefab with caster angle up to 70°. Brakes - weak point: original Brembo (4-piston front) quickly overheat, so they are replaced with Nismo 380mm or AP Racing.

What happens if you install turbines from an R35 GT-R on an RB26DETT?

Original turbines IHI RHF55B from R34 GT-R are designed for 0.8–1.0 bar, while turbines from R35 GT-R (Garrett GT-R) require a pressure of 1.5+ bar. Without preparing the engine (forged pistons, reinforced connecting rods) and fuel system, this will lead to detonation, burnout of the pistons and destruction of the block. In addition, a complete rework of the exhaust system and tuning will be required ECU for new turbine characteristics.

How to choose a Nissan Skyline R34: buyer's checklist

Purchase Skyline R34 - this is always a risk, especially if the car was imported unofficially. Here are the key points to pay attention to:

Pay special attention engine:

• 🔧 On RB26DETT check the condition oil pump — when worn, the oil pressure at idle drops below 1.5 bar.
• 💧 Inspect the oil for metal shavings (a sign of turbine or bearing wear).
• 🔥 Start the engine “cold” - if blue smoke comes out of the exhaust, this is a sign of wear on the turbine or oil rings.

No less important transmission:

• On GT-R Check the 1st and 2nd gear synchronizers - they often wear out during aggressive driving.
• Make sure ATTESA distributes torque correctly (when the front wheels slip, the rear axle should engage smoothly).
• On automatic transmissions (RE4R01A) check the kicks when switching - this is a sign of wear on the solenoids.

Operation and maintenance: tips for owners

Service Skyline R34 - an expensive pleasure. For example, replacing a timing belt with RB26DETT costs 30–50 thousand rubles (including work), and a major overhaul of the engine costs from 500 thousand rubles. Here are the key recommendations:

• 🛢️ Oil: Use only synthetics 5W-40 or 10W-50 (For example, Motul 300V or Liqui Moly Leichtlauf). Change every 5–7 thousand km.
• ⚡ Candles: On GT-R install NGK BCP7ES or Denso IK20 (gap 0.8–1.0 mm).
• 🔥 Turbine: After a long drive, let the engine idle for 1-2 minutes to cool the turbo.
• 💧 Cooling: Change antifreeze every 2 years (Nissan Long Life Coolant) and flush the radiator.

For GT-R it is critical to monitor all-wheel drive system:

• Oil in transfer case (ATTESA) and rear differential change every 60 thousand km.
• Check the condition of the drive shafts - their seals often leak after 100 thousand km.
• If the car is used for drifting, install reinforced axle shafts (Nismo or Cusco).

⚠️ Attention: Never turn off the system HICAS without flashing ECU! This leads to incorrect steering operation and increased wear of the front suspension.

Alternatives to Nissan Skyline R34: what to choose instead

If Skyline R34 seems too expensive or difficult to maintain, consider alternatives from the same segment:

Model	Engine	Pros	Cons
Nissan Skyline R33 GT-R	RB26DETT	30–50% cheaper, easier to repair	Less rigid body, worse handling
Toyota Supra RZ (JZA80)	2JZ-GTE	More reliable motor, potential 1000+ hp.	Heavy body, expensive spare parts
Mitsubishi Lancer Evolution VI	4G63T	Lighter, cheaper to maintain	Less prestigious, weaker suspension
Subaru Impreza WRX STI (GC8)	EJ207	All-wheel drive out of the box, good handling	Problems with the cylinder head, corrosion

If you need exactly Skyline, but R34 too expensive, please note R33 GT-R (1995–1998). It is 30–50% cheaper, and is almost as dynamic as R34 (acceleration to 100 km/h in 5.0–5.2 seconds versus 4.8–5.0 seconds). The main disadvantage is a less rigid body and a more archaic system ATTESA E-TS (without function Pro).

For those looking for reliability, it is better to consider Toyota Supra JZA80 with motor 2JZ-GTE. This engine can handle up to 1000 hp. without major repairs, and spare parts for it are cheaper than for RB26DETT. However Supra 200–300 kg heavier, which affects handling.

FAQ: Frequently asked questions about the 1999 Nissan Skyline R34

Is it possible to legally import the Skyline R34 into Russia in 2026?

Officially, no. Skyline R34 is not certified for Russia, so it can only be imported under the status of “collector car” (over 30 years old) or through “gray” schemes (which is fraught with problems with registration). An alternative is to buy a car that has already been imported and registered before 2015.

How much horsepower does the GT-R R34 really have?

Officially - 280 hp. (according to Japanese standards), but real power RB26DETT is 320–330 hp. on stock firmware. After removing the limiter (for example, by flashing Mine's or HKS) power increases to 380–400 hp. without additional modifications.

What is the service life of the RB26DETT engine?

With careful use and regular maintenance RB26DETT withstands 200–250 thousand km before major repairs. However, most of the copies have already been repaired by 2026 - the original pistons and rings rarely “survive” up to 150 thousand km. After capitalization with forged parts, the engine is capable of driving another 100–150 thousand km.

What kind of oil to put in the GT-R R34 gearbox?

For 6-speed manual Getrag 260 gear oil recommended Nissan MT-XZ (75W-85) or analogues (Red Line MT-90, Motul Gear 300). Volume - 2.8 liters. Change every 50–60 thousand km.

Is it possible to drive the Skyline R34 in winter?

Technically yes, but it's not a good idea. Body R34 poorly protected from corrosion, and salt and reagents accelerate rusting. In addition, the system ATTESA not designed for ice - all-wheel drive only engages when slipping, which can be dangerous on slippery surfaces. If winter driving is unavoidable, install winter tires 225/45 R17 and treat the body with anticorrosive.
