Nissan Skyline GT-R R32/R33/R34, The Complete Buying Guide

Overview

The Nissan Skyline GT-R, R32 (1989-1994), R33 (1995-1998), and R34 (1999-2002), is the most iconic Japanese performance car ever built. The RB26DETT twin-turbocharged inline-six, the ATTESA E-TS all-wheel-drive system, and the Super-HICAS four-wheel steering made the GT-R a technological tour de force that embarrassed European supercars at a fraction of the price. In Australia, the GT-R is royalty. It won Bathurst. It defined an era. And now it costs more than most houses did when it was new.

All three generations share the same RB26DETT engine, a 2.6-litre twin-turbo inline-six that was factory-rated at 206 kW (276 hp) but actually produced closer to 220-240 kW at the flywheel. Nissan deliberately understated the output to comply with the Japanese gentleman’s agreement. The engine is a masterpiece: an iron block, alloy head, individual throttle bodies for each cylinder, and twin ceramic-wheeled T28 turbochargers.

For the Australian buyer in 2026, the GT-R market is eye-watering. R34 GT-Rs are $150,000-300,000+. R32s have climbed to $60,000-120,000. Even the “unloved” R33 commands $50,000-100,000. These are serious sums that demand serious inspection. The GT-R has a deserved reputation for toughness, but it also has specific failure modes that can cost five figures to repair.

What to Look For

Engine, RB26DETT

The RB26DETT is a legendary engine, but it is not invincible. Here is what kills them.

Oil pump failure (R32 and R33, CRITICAL): This is the single most important thing to check on any R32 or R33 GT-R. The factory oil pump uses a drive collar that can shear, causing instant oil starvation and catastrophic engine failure. The aftermarket oil pump collar modification (Nismo or aftermarket) addresses this, a hardened collar replaces the factory item. Ask the seller directly: “Has the oil pump collar been upgraded?” If they do not know what you are talking about, walk away. If the car does not have the collar mod done, budget $500-1,000 to have it fitted (requires gearbox removal on some setups). This is a non-negotiable modification for any R32 or R33 GT-R.

The R34 uses a revised oil pump design that is less susceptible to this failure, but many owners fit the collar mod as insurance regardless.

Turbo condition: The stock T28 turbochargers use ceramic turbine wheels. Ceramic wheels are lighter than steel (which improves spool) but they are brittle. Under high boost or high exhaust temperatures, the ceramic wheel can shatter, sending fragments through the engine. Any car running above stock boost levels MUST have steel-wheeled turbo upgrades. Even on a stock-boost car, ceramic turbos that are 25+ years old should be treated with suspicion.

Check for: turbo shaft play (grab the compressor wheel and feel for radial movement, slight movement is normal, excessive movement means rebuild), oil smoke from the exhaust on boost (turbo oil seal failure), and whining or grinding noises from the turbo housings.

Compression and leak-down: These engines should show 150-170 psi compression across all six cylinders with no more than 10% variation. Low compression on one or two cylinders could indicate worn rings, a damaged head gasket, or, on high-boost modified cars, cracked ring lands. A leak-down test is more diagnostic than a compression test: above 10% leak-down on any cylinder warrants further investigation.

Boost leaks: The RB26’s factory piping and intercooler system is notorious for boost leaks. The factory rubber joins and clamps deteriorate with age. A boost leak test (pressurising the intake system and listening for leaks) should be part of any pre-purchase inspection. Boost leaks cause sluggish performance and can mask other problems.

Head gasket: The RB26 head gasket is the weak point of the engine, particularly on modified cars. The factory multi-layer steel (MLS) gasket is good for stock boost levels but will fail above approximately 1.0-1.2 bar. Signs of head gasket failure: white smoke from the exhaust, coolant loss, milky oil, overheating. On a modified car running above stock boost, an upgraded head gasket (Tomei, HKS, or similar) should have been fitted.

General checks:

• Oil condition: Should be clean and golden/dark brown. Metallic particles in the oil indicate bearing wear.
• Coolant: Check for cross-contamination (oil in coolant or coolant in oil).
• Idle quality: The RB26 should idle smoothly at approximately 800-850 rpm. Hunting or rough idle suggests boost leaks, injector issues, or ECU problems.
• Exhaust smoke: Blue smoke = turbo seals or worn engine. White smoke = head gasket. Black smoke = running rich (AFM issue, injector leak, or poor tune).

ATTESA E-TS (All-Wheel Drive)

The ATTESA E-TS system is what makes the GT-R handle like nothing else from its era. It uses an electronically controlled multi-plate transfer clutch to distribute torque between the rear and front wheels, with the front only receiving power when the rear wheels lose traction.

What to check:

• ATTESA warning light on the dash. If it is illuminated, the system has a fault. Common causes: low transfer case fluid, failed G-sensor (under the centre console), or a faulty ATTESA control unit.
• Drive the car hard through corners. The ATTESA should engage seamlessly, you should feel the front wheels pulling the car through the turn under power. If the car feels exclusively rear-wheel drive, the ATTESA may not be engaging.
• Transfer case fluid: Should be changed every 40,000 km with Nissan-specified ATF. Neglected transfer cases develop bearing wear and clutch pack deterioration.

Super-HICAS (Four-Wheel Steering)

HICAS (High Capacity Actively Controlled Steering) provides rear-wheel steering at higher speeds. Many owners delete it.

Why people delete it:

• The hydraulic HICAS system (R32, R33) develops leaks, and the rear steering can become unpredictable when the system is faulty.
• The electronic HICAS (R34) is more reliable but still adds complexity.
• For track use, fixed rear geometry is preferred for predictability.

What to check:

• HICAS warning light on the dash. If illuminated, the system has a fault.
• Drive the car at highway speed and make gentle lane changes. The rear should feel stable and planted. If the rear feels vague or wanders, the HICAS may be malfunctioning.
• If HICAS has been deleted, check that it was done properly with a lock bar kit, not just by disconnecting hoses and leaving the system to leak.

Rust

GT-Rs are Japanese-built cars that spent their lives in a country that salts its roads in winter. Grey-imported cars (which is the vast majority of GT-Rs in Australia) can have serious rust.

Critical areas:

• Rear wheel arches: The inner and outer arches rust from road spray. Check carefully, the rear quarters on a GT-R are an expensive repair.
• Boot floor: Lift the carpet and spare wheel cover. Water ingress through the boot seal causes corrosion.
• Front subframe and chassis rails: Get under the car and inspect the subframe, control arm mounting points, and chassis rails. Surface rust is normal; structural rust is not.
• Sills (rocker panels): Tap the sills with a screwdriver. Solid metal = good. Hollow or crumbly = bad.
• Turbo heat shield area: The area around the turbochargers and downpipes gets extremely hot. Rust forms on the inner guards and firewall near these heat sources.

The honest truth about Japanese rust: Japan salts its roads more aggressively than most countries. A GT-R that spent its life in Hokkaido or the northern prefectures will have significantly more rust than one from Okinawa or Kyushu. The import auction sheet (if available) lists the auction grade and should note any rust. Grade 3.5 or higher is generally acceptable; below 3.0, expect issues.

Transmission

The GT-R uses a Getrag V160 6-speed manual (R34) or Getrag 6-speed (R32/R33). These are strong transmissions but not indestructible.

What to check:

• Synchro condition: Test every gear, including 1st through 6th and reverse. Grinding or crunching, particularly on 2nd and 3rd, indicates synchro wear.
• Clutch: The factory clutch handles stock power but not much more. If the car is modified, it should have an upgraded clutch. Check for clutch slip under load (engine revs climb but speed doesn’t increase).
• Transfer case: Part of the ATTESA system. Listen for whining or grinding noises.

Electrical and Electronics

• CAS (Crank Angle Sensor) failure: The CAS is located inside the front timing cover and is driven off the exhaust camshaft. It provides the signal for ignition timing and fuel injection. When it fails, the engine will misfire, lose power, or refuse to start. CAS failure is common on all RB26-equipped GT-Rs. Replacement: $300-600. Some aftermarket trigger kits eliminate the CAS entirely.
• AFM (Airflow Meter): The GT-R uses twin AFMs. They can become dirty or faulty, causing rich or lean running. Cleaning with MAF sensor cleaner can help; replacement AFMs are expensive ($300-500 each).
• Boost controller: If the car has an aftermarket boost controller, check that it is properly installed and tuned. A poorly set up boost controller can over-boost the engine and destroy the turbos or engine.

Import History and Compliance

The vast majority of GT-Rs in Australia are grey imports, privately imported from Japan and converted to meet Australian Design Rules (ADR). This is perfectly legal but the compliance process matters.

What to check:

• Compliance plate: The car must have an Australian compliance plate. This confirms it has been inspected and modified to meet ADR requirements (headlight alignment, side intrusion bars, child restraint anchorage, etc.).
• Import approval: The car should have been imported under the Registered Automotive Workshop Scheme (RAWS) or through the now-defunct SEVs scheme.
• Odometer: Japanese domestic market (JDM) cars have odometers in kilometres, which is convenient. However, odometer fraud is not unheard of in the import chain. The Japanese auction sheet records the mileage at time of sale, if the seller has the auction sheet, check that the current odometer is consistent.
• Service history: Japanese owners tend to keep detailed service records. If the car came with Japanese service books, have them translated, they contain valuable information about the car’s maintenance history.

Modified cars are generally worth less than stock equivalents, unless the modifications are documented, professional, and reversible. A heavily modified R32 is worth less than a stock one.

Running Costs

Parts availability: Good for mechanical components. Nismo still produces many parts for the RB26DETT and GT-R chassis. The Australian aftermarket scene (HKS, GReddy, Tomei, Turbosmart) provides extensive support. Body panels and unique GT-R trim pieces are becoming scarce and expensive.

Servicing: Oil changes (5W-30 fully synthetic, 5.0L capacity, use quality oil, Motul or Penrite HPR are popular): $80-120 DIY. Full service: $300-500 DIY, $600-1,200 at a specialist.

Fuel economy:

• Stock: 13-16 L/100 km mixed driving
• Modified (400+ kW): 16-25+ L/100 km depending on how you drive
• All models require 98 RON premium unleaded

Insurance: These cars are expensive to insure. Agreed-value comprehensive insurance is essential. Budget $2,000-5,000+/year depending on the agreed value, your age, and your driving record.

Common repairs to budget for:

• Oil pump collar mod (if not done): $500-1,000
• Turbo rebuild or upgrade to steel-wheel: $2,000-5,000
• CAS replacement: $300-600
• Clutch replacement (upgraded): $1,500-3,000
• Coil pack replacement: $400-800 (set of 6)
• ATTESA transfer case service: $300-500
• HICAS delete kit: $200-400

Which Variant?

R32 GT-R: The original “Godzilla.” The lightest, the rawest, and the most engaging to drive. It is also the one most likely to have the oil pump collar problem, and it has the most basic interior. The R32 is the driver’s choice, it has the most analogue feel of the three generations.

R33 GT-R: The forgotten middle child, and arguably the best value in 2026. It is larger and more refined than the R32, with improved suspension geometry and better straight-line stability. The R33 set a production car lap record at the Nurburgring. It is undervalued relative to the R32 and R34 and offers the most car for the money.

R34 GT-R: The poster child. The most advanced GT-R, with the Multi-Function Display (MFD) showing turbo boost, oil and water temperature, and G-forces. The R34 is the most collectible, the most desirable, and the most expensive. It is also the most likely to have been stored rather than driven, many R34s have spent their lives as garage queens.

V-Spec: Available on all three generations. Adds ATTESA E-TS Pro (with an active rear limited-slip differential), Brembo brakes, firmer suspension, and specific wheels. The V-Spec is the driver’s variant and commands a consistent premium.

The Verdict

The GT-R is one of the truly great performance cars. The RB26DETT engine, the ATTESA all-wheel-drive system, and the overall engineering quality make it a car that can embarrass much more expensive machinery. But at 2026 prices, you are buying an asset as much as a car. Have any prospective purchase inspected by a GT-R specialist, not a generic mechanic, not your mate who is “good with cars,” but someone who works on GT-Rs every day. The oil pump collar, the turbo condition, the ATTESA health, and the rust assessment all require specific knowledge.

Buy with your head, not your heart. The GT-R will look after you if you look after it. Neglect it, and it will punish you with repair bills that match its price tag.
