4.8L V8 Twin-Turbo - Turbo S
Petrol
Listen closely for any rhythmic clicking or knocking while turning at low speeds; the air suspension compressors and control arms on these 957 models are components that can show signs of age after many years on Kiwi roads.
Check this by idling the vehicle for a few minutes while parked and observe the exhaust; on high-performance V8 units, it is common to monitor for excess smoke, which might suggest that the turbo seals could eventually benefit from professional inspection.
While driving at various speeds, perform a heavy braking test in a safe area; the massive calipers are powerful, but ensure the pedal feels firm, as worn brake rotors can be a costly maintenance item on the Turbo S specification.
Operate every interior electronic feature, specifically the infotainment and climate controls, as the aging wiring looms and complex electronic modules can occasionally exhibit intermittent behavior in cars of this vintage.
Usually the time to evaluate the health of the cooling system components and plastic coolant pipes which are common points of focus for preventative maintenance.
Consider a full inspection of the drivetrain mounts and the driveshaft center support bearing to ensure the smooth delivery of the V8's significant power.
A major milestone where a comprehensive service history is vital, focusing on the timing chain tensioners and complete fluid flush cycles for the transmission and differentials.
Ensure the service history includes regular oil changes using high-quality synthetic lubricants, as the twin-turbo setup relies on clean oil for longevity.
Verify that the cooling system has been serviced, specifically checking for any signs of brittle or aged plastic connectors.
Check the condition of the tires and ensure they are a matching set of high-performance rubber, which is crucial for handling the weight and power of the Turbo S.
Ask the seller if the spark plugs and ignition coils have been replaced recently, as these are critical for maintaining the engine's smooth power delivery.
Inspect the undercarriage for any signs of past oil leaks or moisture around the air struts to maintain the vehicle's signature ride quality.
Estimated repair costs if issues arise
If the vehicle begins to sit unevenly or the compressor becomes loud, you might eventually need to budget for the replacement of air struts or the compressor unit. It's a common consideration for vehicles of this age.
Depending on the car's history, you might eventually need to budget for a turbo service or refurbishment. This involves inspecting the seals and bearings to ensure the twin-turbos continue to perform as intended.
The Turbo S features large-diameter braking systems. If these components reach the end of their service life, it is wise to factor in the cost of high-performance replacement parts for future budget planning.
