Nissan Skyline R34 Special Editions: Z-Tune, NISMO 400R, V-Spec & Nur Guide

The Nissan Skyline R34 GT-R is already a JDM legend, but within the BNR34 lineup exists a hierarchy of special editions that represent the absolute pinnacle of Nissan's engineering. From the track-focused V-Spec to the impossibly rare BNR34 Z-Tune, these limited-production models are the holy grail for Skyline collectors. Understanding the differences between V-Spec, V-Spec II, V-Spec II Nur, NISMO 400R, and the R34 Z-Tune is essential for any serious GT-R buyer.

R34 GT-R V-Spec: The Track-Ready Standard

The V-Spec (Victory Specification) was available from launch in 1999. Nissan positioned it as the performance-oriented variant of the standard R34 GT-R, building on the successful V-Spec formula established with the R32 and R33 generations.

V-Spec Key Upgrades Over Standard GT-R

• ATTESA E-TS Pro with Active LSD: Enhanced all-wheel-drive system with electronically controlled limited-slip differential at the rear, providing sharper turn-in and better traction out of corners
• Brembo brakes: Gold-painted Brembo calipers with larger rotors (324mm front, 300mm rear)
• Carbon fiber rear diffuser: Functional aero piece reducing rear lift at high speeds
• Stiffer suspension: Revised spring rates and damper settings tuned for circuit use
• 17-inch forged RAYS wheels: Lighter than standard wheels with wider rear fitment (9J front, 9.5J rear)

The V-Spec produced the same 280 hp (actual ~320 hp) RB26DETT as the standard GT-R, but the chassis improvements made it noticeably faster on track. It was approximately ¥500,000 more expensive than the standard model when new.

R34 GT-R V-Spec II: The Refined Evolution

Released in 2000, the V-Spec II refined the V-Spec formula with several meaningful upgrades that addressed feedback from owners and racing teams.

• Carbon fiber bonnet (hood): NACA-ducted carbon hood saving approximately 5 kg over the steel original. This is the easiest visual identifier of a V-Spec II
• Revised N1 water pump: More durable coolant pump addressing a known weakness in earlier R34s
• Upgraded brake pads: Higher-temperature compound for sustained circuit use
• Revised ECU mapping: Slightly improved throttle response and boost control
• Gold-painted engine cover: V-Spec II specific detail (standard cars have black covers)

The V-Spec II is widely considered the best "standard production" R34 GT-R. The carbon bonnet became so desirable that many standard GT-R and V-Spec owners retrofitted it, making visual identification unreliable. Always verify with chassis number and Nissan build records.

R34 GT-R V-Spec II Nur: The Final Standard R34

The V-Spec II Nur (Nurburgring edition) was released in February 2002 as the final evolution of the standard-production R34 GT-R. Limited to approximately 750 units, it was Nissan's farewell to the RB26DETT era and is named after the Nurburgring Nordschleife where the GT-R earned its reputation.

Nur-Exclusive Upgrades

• N1-spec RB26DETT engine: Hand-balanced, individually dyno-tested engine blocks with tighter tolerances. Each engine came with a numbered plate signed by the builder
• Reinforced engine block: Thicker cylinder walls and strengthened main bearing caps, rated for higher boost levels
• HKS turbochargers (optional): Some Nur models came with factory-fitted HKS turbos producing an estimated 330+ hp
• Exclusive Millennium Jade (color code: JW0): The most iconic Nur color, a deep metallic green exclusive to V-Spec II Nur and M-Spec Nur models
• All V-Spec II features included: Carbon bonnet, Active LSD, Brembo brakes, carbon diffuser

Millennium Jade V-Spec II Nur examples are among the most valuable R34 GT-Rs in existence, with auction prices regularly exceeding ¥30,000,000-¥50,000,000 ($200,000-$330,000+ USD). Even in other colors, the Nur commands a significant premium over the V-Spec II. For general R34 GT-R buying advice, see our R34 GT-R Import Guide.

R34 GT-R M-Spec and M-Spec Nur

Often overlooked in the V-Spec vs Nur debate, the M-Spec (Mizuno Specification, named after GT-R chief engineer Kazutoshi Mizuno) took a different approach. Rather than maximizing track performance, the M-Spec focused on grand touring comfort while maintaining GT-R performance.

• Ripple control dampers: Softer, more compliant suspension for road comfort
• Leather Recaro seats: Semi-reclining leather sport seats unique to M-Spec
• Gold-painted calipers: Matching V-Spec Brembo setup
• No rear diffuser: Cleaner rear aesthetic
• M-Spec Nur variant: Combined M-Spec comfort with Nur's N1 engine and Millennium Jade option

M-Spec production was limited to approximately 285 units, and M-Spec Nur to around 164 units. These are among the rarest factory R34 GT-Rs and prices reflect their scarcity, typically ¥25,000,000-¥45,000,000 ($165,000-$300,000 USD) for clean examples.

NISMO 400R: The Factory Supercar

The NISMO 400R is not technically an R34, it was based on the R33 GT-R (BCNR33), but it deserves mention as the pinnacle of NISMO's GT-R program and the direct predecessor to R34-based NISMO creations. Only 44 units were ever produced, making it one of the rarest Skylines in existence.

400R Specifications

• Engine: RB-X GT2, a completely rebuilt 2.8L RB26 with N1 block, increased stroke, forged internals, and twin IHI turbochargers producing 400 PS (394 hp) at 6,800 rpm and 47.8 kgm (346 lb-ft) at 4,400 rpm
• Transmission: Strengthened Getrag 6-speed manual with short-throw shifter
• Suspension: Fully adjustable NISMO-spec coilovers with pillow ball mounts
• Brakes: NISMO-spec Brembo 4-pot front, 2-pot rear with slotted rotors
• Aero: Full NISMO 400R body kit including front bumper with integrated oil cooler ducts, extended side skirts, rear diffuser, and adjustable carbon fiber GT wing
• Wheels: NISMO-specific LMGT1 18-inch forged wheels
• Weight: 1,468 kg (approximately 90 kg lighter than standard R33 GT-R)
• Top speed: 300 km/h (186 mph), hence the "400" name representing combined PS + top speed

NISMO 400R values have skyrocketed in recent years. The few examples that have traded hands publicly have sold for ¥80,000,000-¥150,000,000+ ($530,000-$1,000,000+ USD). They are true collector-grade vehicles that rarely appear on the open market. Most are held in private collections in Japan and the Middle East.

BNR34 Z-Tune: The Ultimate Skyline GT-R

The BNR34 Z-Tune is the undisputed king of the Skyline GT-R lineage. Created by NISMO in 2004-2005 as the ultimate expression of RB26 power, only 19 units were ever built (plus 1 prototype), making it one of the rarest and most valuable Japanese cars ever produced.

Z-Tune Build Process

Each Z-Tune started as a used R34 GT-R that was completely stripped to a bare shell at NISMO's Omori Factory. The cars were then rebuilt from the ground up with race-derived components:

• Engine: Z2 engine, a complete NISMO rebuild of the RB26DETT featuring a stroked 2.8L bottom end (same spec as the 400R's RB-X GT2), IHI turbochargers, and individual throttle bodies. Official output: 500 PS (493 hp) at 7,200 rpm and 540 Nm (398 lb-ft) at 5,200 rpm
• ECU: NISMO-programmed Motec M800 standalone engine management system
• Transmission: Strengthened Getrag 6-speed with OS Giken triple-plate clutch
• Suspension: Sachs racing dampers with NISMO-spec springs, adjustable front and rear
• Brakes: NISMO-spec Brembo 6-pot front, 4-pot rear with 2-piece floating rotors
• Aero: Complete Z-Tune body kit with carbon fiber bonnet (featuring signature Z-Tune NACA duct), extended front fenders, unique front bumper, and rear diffuser
• Wheels: NISMO LMGT4 forged wheels, 18x9.5 front and 18x10.5 rear
• Weight: 1,600 kg (heavier than standard due to extensive strengthening)
• Color: All Z-Tunes were finished in Z-Tune Silver (KY0)

Z-Tune Performance

NISMO's target was to create a GT-R capable of lapping the Nurburgring Nordschleife in under 7 minutes and 30 seconds, a time that would have been competitive with contemporary supercars like the Porsche 911 GT3 and Ferrari 360 Challenge Stradale. The Z-Tune achieved a verified 0-100 km/h time of approximately 3.8 seconds and a top speed exceeding 290 km/h.

Z-Tune Value and Market

The BNR34 Z-Tune is the most valuable Skyline GT-R ever built. In recent private sales, Z-Tunes have reportedly traded for ¥150,000,000-¥300,000,000+ ($1,000,000-$2,000,000+ USD). The prototype Z-Tune (chassis #0) was reportedly offered for over $2.5 million. These are investment-grade vehicles in the same category as classic Ferraris and Porsches.

How to Verify Authentic Special Editions

With values this high, fakes and misrepresented cars are a real concern. Here's how to verify authenticity:

• Chassis number: V-Spec models use BNR34-00xxxx with specific number ranges. The Nissan heritage department can verify build specifications from chassis number
• NISMO plate: Z-Tune and 400R have individual NISMO serial number plates in the engine bay
• Build sheet: Request the original Japanese build sheet (kouin-sho) showing factory-specified options
• Carbon bonnet: Genuine V-Spec II/Nur carbon bonnets have a specific weave pattern and weight. Aftermarket carbon hoods are common replacements
• Millennium Jade paint code: JW0 should appear on the compliance plate. This color was exclusively available on Nur models
• Engine number: Nur models have N1-block engines with specific casting numbers and individual build plates

For any serious purchase above ¥20,000,000, commissioning a professional pre-purchase inspection through a Nissan Prince dealer or NISMO Omori Factory is strongly recommended. Many auction agents offer this service. See our auction guide for more on the buying process.

Frequently Asked Questions

What is the rarest R34 GT-R?

The NISMO R34 GT-R Z-Tune is the rarest, with only 19 production units plus 1 prototype ever built. Each was hand-assembled at NISMO's Omori Factory from 2004-2005. The NISMO 400R (R33-based) is also exceptionally rare at 44 units. Among standard-production R34s, the M-Spec Nur (approximately 164 units) is the rarest variant.

How much is a BNR34 Z-Tune worth?

BNR34 Z-Tune values currently range from ¥150,000,000-¥300,000,000+ ($1,000,000-$2,000,000+ USD) in private sales. The prototype Z-Tune has been reportedly valued at over $2.5 million. As only 20 examples exist worldwide (including the prototype), prices are expected to continue appreciating as collector interest in Japanese sports cars grows.

What is the difference between V-Spec and V-Spec II?

The V-Spec II added a carbon fiber NACA-ducted bonnet (saving approximately 5 kg), a revised N1 water pump for improved cooling reliability, upgraded brake pads rated for higher temperatures, and revised ECU mapping. Both share the ATTESA E-TS Pro with Active LSD, Brembo brakes, and carbon rear diffuser. The V-Spec II is generally considered the better buy for its improved reliability features.

What does Nur mean on the R34 GT-R?

Nur stands for Nurburgring, the famous German racing circuit where the Skyline GT-R earned its legendary performance reputation. The V-Spec II Nur and M-Spec Nur were the final production R34 GT-Rs, released in 2002, featuring the hand-built N1-spec RB26DETT engine with strengthened internals. The Nur is Nissan's tribute to the track that defined the GT-R's legacy.

Can I import a V-Spec II Nur to the USA?

The V-Spec II Nur was produced in 2002, which means it becomes 25-year-rule eligible for US import in 2027. As of 2026, 1998-2001 R34 GT-Rs are importable. For Nur models specifically, you'll need to wait until 2027 or explore show/display exemptions through NHTSA. For other countries like the UK, Australia, and Canada, import is generally possible now through standard compliance procedures.
