Petrol
Check the transmission response | Detail: During your test drive, observe if the CVT transmission shifts smoothly under load, as these units can occasionally show hesitation or 'judder' in vehicles of this vintage.
Listen for timing chain rattle | Detail: On a cold start, pay close attention to the engine bay for any metallic rattling sounds; while the SR20 engine is robust, age-related wear on chain tensioners can happen.
Test the sliding door mechanisms | Detail: Operate the sliding doors manually and electronically; if they catch or stall, it may indicate that the rollers or the power-door cables require some routine lubrication or adjustment.
Inspect the dashboard electronics | Detail: Check that all climate control and infotainment displays are fully illuminated, as aging interior electronics can sometimes suffer from display fade or pixel dropouts in older Japanese imports.
Usually marks the point where suspension bushings and engine mounts might start showing their age.
Recommended timeframe to verify that the turbocharger's oil feed lines are clear and functioning optimally.
Consider a comprehensive review of the cooling system, including the radiator and hoses, to prevent overheating risks.
Prioritize regular engine oil changes every 5,000km to keep the turbocharger healthy.
Check the condition of the CV boots for any cracking or grease leaks.
Ensure the coolant is fresh and the cooling system is bled correctly to avoid air locks.
Inspect the spark plugs regularly, as the SR20DET is sensitive to ignition health.
Keep an eye on the transmission fluid color and ensure it is serviced according to age, not just mileage.
Estimated repair costs if issues arise
Given the age of the M12 series, the turbo seals may eventually wear. It's wise to set aside some funds in case you need a professional rebuild or a core replacement.
If the ride feels a bit 'loose' or clunky over bumps, you might eventually need to budget for new shocks and control arm bushings to bring that comfortable ride quality back.
Keeping the transmission fluid fresh is the best way to extend the life of the unit. You might eventually need to budget for a professional flush and filter replacement.
