2.5L RB25DET Neo - AWD (RS Four V)
Petrol
Test drive task: Gently accelerate in 2nd or 3rd gear. | Observation: Be mindful of any hesitation or 'stuttering' under boost, as the factory coil packs on the Neo engine can show their age through ignition misfires.
Test drive task: Perform a few low-speed figure-eight maneuvers in a parking lot. | Observation: Listen closely for any clicking or binding sounds from the front CV joints, as the AWD system components are now reaching an age where wear is occasionally noted.
Check this by: Inspecting the coolant overflow tank and radiator fluid color. | Observation: It is common to look for signs of oil mixing or crusty residue, as these older cooling systems require consistent maintenance to keep the RB25DET operating at optimal temperatures.
Check this by: Checking for dampness under the floor mats in the footwells. | Observation: While less common, some examples may develop minor seal degradation around the windscreen or sunroof, so ensuring the cabin stays dry is a good practice during your inspection.
Usually marks the point where the first major timing belt service should have been completed; ensure the tensioner and water pump were addressed.
Often the time to evaluate the suspension bushings and arm joints, which may start to feel a bit tired compared to factory specifications.
Consider a comprehensive check of the turbocharger health and internal gasket seals, as the RB series engines often benefit from a 'freshen up' at this stage.
Prioritize oil changes every 5,000km to keep the Variable Valve Timing (VVT) solenoid happy.
Monitor the transmission fluid condition, especially if the car is used for regular city driving.
Keep an eye on the rubber intake piping for any cracks that could introduce vacuum leaks.
Ensure the earth points are clean and secure to prevent odd electrical gremlins often found in older Japanese imports.
Regularly inspect the condition of the radiator hoses as the original factory items may become brittle over time.
Estimated repair costs if issues arise
If the turbo shows signs of shaft play or excessive oil smoke, you might eventually need to budget for a rebuild or a high-quality replacement to maintain that signature boost response.
To keep the handling sharp and comfortable, it is common to consider replacing aged rubber bushings with polyurethane or new factory-style alternatives over time.
Because the RB25DET generates significant heat, planning for a radiator upgrade or full hose replacement is a wise move for long-term peace of mind in our NZ climate.
