Known Issues
Timing Drift and Ignition Instability€400-1,200 · 80,000-150,000 kmHIGH
The RB26DETT is known to exhibit timing instability, particularly on aged or modified units. Timing drift can cause misfires, detonation and potential engine damage if left unaddressed. Worn distributor components, aged coilpacks and stretched timing components all contribute.
Misfires under load
Rough idle
Timing wander visible on timing light
Power loss at high RPM
DIY: Moderate
Turbocharger Wear and Oil Feed Issues€800-2,500 · 100,000-180,000 kmHIGH
The twin ceramic-wheeled Garrett turbochargers are aging on all surviving units. Oil feed and return lines degrade over time, starving bearings. Ceramic compressor wheels are brittle and can shatter under boost or heat cycling, sending debris into the engine.
Turbo whine or grinding
Blue smoke at startup or under boost
Loss of boost pressure
Oil leaks at turbo flanges
DIY: Hard
Aged Rubber Hoses and Coolant System Degradation€300-900 · 80,000-160,000 kmHIGH
All R32 GT-Rs are now 30+ years old. Original rubber coolant, boost and vacuum hoses are brittle, cracked or collapsing internally. Thermostat housings and water pump seals are frequently weeping. Cooling system failures can cause rapid overheating and head gasket damage.
Coolant loss without visible leak
Overheating under load
Collapsed boost hoses causing boost drop
Visible cracking on hoses
DIY: Moderate
Unstable Idle and Fuel Delivery Issues€200-700 · 70,000-140,000 kmMODERATE
Aged fuel injectors, the NISMO fuel pressure regulator and the original ECU wiring harness can all contribute to rough or unstable idle. The RB26's six individual throttle bodies require balanced synchronisation; vacuum leaks from aged intake boots cause lean conditions.
The factory wiring harness on R32-era vehicles is now extremely aged. Insulation becomes brittle and cracks, connectors corrode, and the ECU connector pins oxidise causing intermittent faults. This is compounded on any car that has been modified or imported with wiring alterations.
Intermittent ECU faults
Random sensor errors
Electrical gremlins with no pattern
Connector corrosion visible
DIY: Hard
Oil Leaks from Cam Cover and Rear Main Seal€150-600 · 80,000-160,000 kmMODERATE
The RB26DETT's cam covers and rear main seal are common leak points on aged engines. Gaskets harden over decades and minor leaks are nearly universal on unrestored examples. Not immediately catastrophic but can contaminate the exhaust and become a fire risk.
Oil smell when engine is warm
Visible oil weeping from cam cover rail
Oil residue on bell housing area
Smoke from exhaust manifold area
DIY: Easy
Previous Tuning and Abuse History€0-5,000 · 0-100,000 kmLOW
The vast majority of surviving R32 GT-Rs have been modified or tuned. Engines that have been run on incorrect maps, cheap boost controllers or oversized turbos without supporting upgrades may have hidden internal damage including spun bearings or worn ring lands.

Buying Checklist
Perform a full compression and leakdown test on all six cylinders — anything below 150 psi or more than 10% variance is a red flag
Check both turbos for shaft play and inspect oil feed and return lines for cracking, blockage or leaks
Pressure test the entire cooling system and physically inspect every rubber hose for brittleness, cracking or internal collapse
Inspect the engine bay wiring harness for cracked insulation, corroded connectors and evidence of amateur modification or re-wiring
Obtain full tuning and modification history — request dyno sheets, ECU map version and a list of all engine work performed
Check crankcase breather output for excessive blowby smoke which indicates worn rings or bearings from past abuse
Service Reality
Community oil interval5,000 km
Oil specification10W-40 or 15W-50 full synthetic; many owners use 5W-40 full synthetic in cooler climates. Short drain intervals are critical on a forced-induction engine of this age.
Est. ownership cost (2yr)€2,500–6,000 per year depending on condition at purchase, modification level and whether deferred maintenance needs addressing

Buying Advice
The R32 GT-R with RB26DETT is a genuine icon but every surviving example is now over 30 years old, meaning mechanical condition varies enormously and budget for restoration rather than just purchase price. Prioritise cars with documented maintenance and honest tuning histories over low-mileage claims that cannot be verified. Budget a minimum of €3,000–5,000 on top of the purchase price for cooling system, hose and seal refreshment on any unrestored car. The engine itself is genuinely capable and long-lived when cared for, but neglected or abused examples can carry catastrophic hidden damage that only a thorough inspection will reveal.
