Nissan Skyline R34 GTT vs GT-R: The Budget Skyline Import Guide

The Nissan Skyline R34 GT-R is a JDM legend that commands $50,000-$200,000+ at auction. But what if you could get 80% of the Skyline R34 experience for 20% of the price? Enter the R34 GTT (25GT Turbo), the overlooked twin of the GT-R that shares the same iconic body, similar interior, and a turbocharged RB engine, all for a fraction of the cost. For buyers who want a Skyline from Japan without the GT-R price tag, the R34 GTT is the smartest choice in 2026.

R34 GTT vs GT-R: Key Differences Explained

The R34 Skyline lineup was extensive, but the two models most buyers care about are the GTT (ER34) and the GT-R (BNR34). Here's how they compare on the specifications that matter:

Engine

• R34 GTT: RB25DET NEO inline-six, 2.5L single turbo, 280 hp / 289 lb-ft
• R34 GT-R: RB26DETT inline-six, 2.6L twin turbo, 280 hp / 293 lb-ft (actual output ~320 hp)

On paper, both cars produce the same 280 hp (gentleman's agreement). In reality, the GT-R's RB26DETT puts out approximately 320 hp stock, while the GTT's RB25DET NEO is closer to 250-260 hp at the wheels. However, the RB25DET is no slouch. It responds extremely well to modifications and can reliably produce 350-400 hp with bolt-on upgrades.

Drivetrain

• R34 GTT: Rear-wheel drive (FR), 5-speed manual or 4-speed automatic
• R34 GT-R: ATTESA E-TS Pro all-wheel drive, 6-speed Getrag manual only

This is the biggest functional difference. The GT-R's ATTESA system provides legendary all-weather traction and launch capability. The GTT's rear-wheel drive makes it lighter, simpler, and more playful. For drifting enthusiasts, the GTT is actually the preferred choice. Many JDM drift car builds start with an R34 GTT chassis.

Weight & Dimensions

• R34 GTT (4-door): 1,430 kg, 4,675mm length
• R34 GTT (2-door): 1,410 kg, 4,580mm length
• R34 GT-R: 1,560 kg, 4,600mm length

The GTT is 130-150 kg lighter than the GT-R, which significantly improves handling response and braking. That weight difference is equivalent to removing a passenger. Less weight also means better fuel economy, less brake wear, and less stress on suspension components.

R34 GTT Variants: Which One to Buy

The R34 GTT was available in several configurations. Understanding these helps you find the right car:

• 25GT Turbo (ER34, 2-door coupe): The most desirable GTT variant. Same coupe body style as the GT-R, RB25DET NEO, 5MT or 4AT. Best for tuning builds and GT-R visual conversion
• 25GT Turbo (ER34, 4-door sedan): Same engine and drivetrain as the coupe but with rear doors. More practical, significantly cheaper at auction, and still looks stunning with proper modifications
• 25GT (non-turbo, ER34): RB25DE naturally aspirated, 200 hp. Budget option that can be turbo-swapped, but starting with a factory turbo car is recommended
• 25GT-V (HR34): RB25DE with HICAS four-wheel steering. Interesting tech but adds maintenance complexity

R34 GTT Prices in 2026

Here's where the GTT really shines. While GT-R prices continue to climb, the GTT remains relatively affordable:

• R34 GTT 2-door (manual): ¥2,000,000-¥5,000,000 ($13,200-$33,000 USD)
• R34 GTT 2-door (auto): ¥1,500,000-¥3,500,000 ($10,000-$23,000 USD)
• R34 GTT 4-door (manual): ¥1,000,000-¥2,500,000 ($6,600-$16,500 USD)
• R34 GTT 4-door (auto): ¥600,000-¥1,800,000 ($4,000-$12,000 USD)
• R34 GT-R (BNR34) for comparison: ¥8,000,000-¥30,000,000+ ($53,000-$200,000+ USD)

The price difference is staggering. A clean R34 GTT 2-door manual costs roughly what a heavily damaged GT-R goes for at auction. For detailed R34 GT-R pricing, see our R34 GT-R Import Guide.

Tuning the R34 GTT: RB25DET Build Guide

The RB25DET NEO in the R34 GTT is a robust engine with excellent tuning potential. Here's a realistic power progression:

Stage 1: Bolt-Ons (300-350 hp)

• Aftermarket exhaust (downpipe + cat-back): $800-$1,500
• Boost controller (raise to 1.2 bar): $200-$400
• Cold air intake: $200-$400
• ECU tune (Power FC or Link): $1,000-$2,000
• Total: $2,200-$4,300 for 300-350 hp

Stage 2: Turbo Upgrade (400-500 hp)

• Garrett GT3076R or equivalent: $1,500-$2,500
• 550cc or 740cc injectors: $400-$600
• Fuel pump upgrade (Walbro 255): $150
• Intercooler upgrade: $500-$1,000
• Standalone ECU tune: $1,500-$2,500
• Total: $4,050-$6,750 for 400-500 hp

Stage 3: Forged Internals (500-700 hp)

• Forged pistons & rods (CP/Manley): $2,000-$3,000
• Head studs & gasket: $500-$800
• Larger turbo (GT35R or equivalent): $2,000-$3,500
• Full fuel system upgrade: $1,000-$1,500
• Total: $5,500-$8,800 for 500-700 hp

R34 GTT to GT-R Conversion: Is It Worth It?

A popular approach is converting an R34 GTT to look like a GT-R. The most common conversion includes fitting a BNR34 front bumper, GT-R bonnet, and GT-R rear wing. Some owners go further with RB26DETT engine swaps and ATTESA AWD conversions, though this adds significant cost and complexity.

Visual conversion cost is typically ¥500,000-¥1,000,000 ($3,300-$6,600 USD) for genuine Nissan GT-R body parts. Full mechanical conversion (RB26 swap + ATTESA + Getrag 6MT) can exceed ¥3,000,000 ($20,000 USD), at which point the total investment approaches GT-R territory. Most enthusiasts agree that keeping the GTT's RB25DET and RWD layout while doing a visual conversion offers the best value.

R33 GTS-t: The Even More Affordable Alternative

If the R34 GTT is still beyond your budget, consider the R33 GTS-t (ECR33). It uses the earlier RB25DET (non-NEO) with very similar power output and tuning potential. R33 GTS-t prices start at just ¥400,000-¥1,200,000 ($2,600-$8,000 USD) at Japanese auction, making it one of the most affordable ways into the Skyline family. The R33 GTS-t is fully 25-year-rule eligible for US import and shares the same iconic round taillight design.

Importing an R34 GTT: Current Eligibility

The R34 Skyline was produced from 1998-2002. As of 2026, R34 GTT models from 1998-2001 are 25-year-rule eligible for US import. By 2027, all R34 production years will be importable. For other markets, the R34 GTT can typically be imported to the UK, Australia, and Canada through standard compliance channels. Detailed procedures are in our JDM import guide.

Frequently Asked Questions

What is the difference between R34 GTT and GT-R?

The R34 GTT uses a 2.5L RB25DET single-turbo engine with rear-wheel drive, while the GT-R has a 2.6L RB26DETT twin-turbo with ATTESA all-wheel drive. The GT-R also features a 6-speed Getrag manual, Brembo brakes, and stiffer suspension. The GTT is 130-150 kg lighter and costs 75-90% less at auction. Both share the same body shell, interior, and iconic R34 Skyline styling.

How much HP can an R34 GTT make?

Stock, the R34 GTT produces approximately 250-260 hp at the wheels. With bolt-on modifications and a tune, 300-350 hp is easily achievable. A turbo upgrade pushes output to 400-500 hp. With forged internals and a large turbo, 600-700 hp is possible. The RB25DET's iron block is strong enough for 500+ hp on stock internals with proper tuning.

Is the R34 GTT good for drifting?

The R34 GTT is an excellent drift platform. Its rear-wheel drive layout, turbocharged engine, and 50:50 weight distribution make it naturally suited for sideways driving. The 4-door sedan version is especially popular in grassroots drifting due to its lower price. Many professional D1GP drivers have used ER34 chassis in competition.

Can I make an R34 GTT look like a GT-R?

Yes. The most common visual conversion involves fitting a BNR34 front bumper, GT-R hood with NACA duct, and GT-R rear wing. Genuine Nissan parts cost ¥500,000-¥1,000,000 ($3,300-$6,600 USD). Aftermarket replica parts are available for less. The conversion is bolt-on for most exterior components, though some modifications to bumper supports may be needed.

Is the R34 GTT legal to import to the USA?

R34 GTT models from 1998 and 1999 are currently 25-year-rule eligible for US import. The 2000 model year becomes eligible in 2025, and all R34 production years (through 2002) will be legal by 2027. No special exemptions or show/display permits are needed for 25-year-eligible vehicles.
