Petrol
Check this by inspecting the boot floor and strut towers for any signs of surface rust or previous accident repairs, as these are common areas for older performance imports.
While driving at low speeds, gently apply the brakes to listen for any pulsating or uneven pedal feel, which may indicate the discs have warped due to past spirited driving.
During the cold start, observe the exhaust for any excessive blue or white smoke, as this is a common point to consider when assessing the health of the twin-turbo system and valve seals.
Check this by testing all electrical accessories, specifically the HICAS rear-wheel steering warning lights, as the complex wiring in these models can occasionally show its age.
Usually marks the point where original factory cooling hoses and rubber bushings have reached the end of their design life.
A common window where the RB26DETT may benefit from a professional compression test to verify ring and valve health.
Typically when internal sensors, like the Air Flow Meters (AFMs), might begin to show drifting voltage signals.
Keep the oil fresh with high-quality synthetic lubricants to keep the RB26 internals happy.
Check the coolant levels and the condition of the radiator to ensure the engine stays cool under pressure.
Monitor your spark plugs, as this engine thrives when the ignition system is firing perfectly.
Give the timing belt its due attention, as keeping this on schedule provides peace of mind for the heart of the engine.
Look after the ATTESA 4WD system by ensuring the hydraulic fluid is clean and functioning smoothly.
Estimated repair costs if issues arise
Given the age of these twin-turbo units, you might eventually need to budget for a rebuild if you notice sluggish boost or oil consumption, which involves stripping and reconditioning the internal cartridges.
To keep the RB26 running reliably, it is common practice to refresh the timing belt, tensioners, and water pump every 100,000km or every 7-10 years, whichever comes first.
If the clutch begins to feel heavy or slips during spirited driving, you might eventually need to budget for a replacement; choosing the right organic or multi-plate setup is key to retaining factory-like drivability.
