2.6L RB26DETT Twin Turbo - GT-R AWD
Petrol
While driving, listen closely for any metallic clunking from the ATTESA AWD system during tight, low-speed turns to ensure the transfer case is operating smoothly.
Check this by idling the car when fully warmed up; observe the oil pressure gauge, as low readings at idle in these RB26 engines may suggest that internal bearing clearances should be assessed.
While stationary, shift through all gears carefully, specifically feeling for any resistance or 'notchy' movement in the synchros, as heavy usage can impact the longevity of the Getrag 6-speed transmission.
Carefully inspect the strut towers and rear chassis rails for any signs of surface rust or previous stress fractures, which can occur in imported vehicles depending on their regional history.
Usually marks the point where original factory turbos and cooling hoses may show signs of perishing.
A common window where the timing belt and water pump assembly should be verified, regardless of the perceived condition.
Often the time to consider a professional health check on the internal engine seals and auxiliary sensors like the MAFs.
Perform a high-quality synthetic oil change every 5,000km to keep those twin turbos happy.
Keep a close eye on your coolant levels and the condition of the radiator hoses as the aging plastic parts can become brittle.
Regularly inspect the air filter elements; clean or replace them to ensure the RB26 breathes freely.
Ensure the ignition system is refreshed with high-quality spark plugs to maintain that smooth, iconic idle.
Check your battery terminal connections and earth points regularly, as electrical gremlins are known to hide in aged wiring looms.
Estimated repair costs if issues arise
If the car has seen spirited driving, you might eventually need to budget for a turbocharger refurbishment. This involves balancing the turbine wheels and replacing seals to maintain peak boost efficiency.
To keep the legendary AWD system functioning precisely, it is wise to plan for periodic fluid flushes and potential solenoid cleaning. It’s a specialized job that ensures your drive remains responsive.
Depending on the car's history, you might eventually need to budget for a cylinder head inspection, which includes valve clearance adjustments and new gaskets to keep the engine performing at its best.
