2.0L (EJ20) - Twin Turbo RS/GT
Petrol
Check the boost delivery while accelerating in 3rd gear. | Description: Ensure the transition between the primary and secondary turbo is smooth. Hesitation or a sudden loss of power during the 'transition zone' around 4,000-4,500 RPM suggests the complex vacuum solenoid system may need attention.
Monitor the coolant temperature gauge during city driving. | Description: It is worth keeping an eye on the needle to ensure it stays steady. Fluctuations in traffic could indicate a cooling system that is starting to tire or a potential head gasket issue, which is a known consideration for EJ-series engines of this era.
Perform a cold start with the bonnet open. | Description: Listen for any rhythmic tapping sounds. While these engines can be a bit 'chatty' when cold, persistent loud tapping may suggest that the hydraulic lash adjusters or valve clearances could benefit from a professional assessment.
Verify the transmission engagement at a standstill. | Description: When shifting from Park to Drive or Reverse, note any delay or harsh clunking. A healthy gearbox should engage promptly without significant shuddering.
Major timing belt service, idler pulleys, and water pump replacement are essential at this interval.
Expect to inspect suspension bushings and potential replacement of wheel bearings, which often show wear by this stage.
Consider a comprehensive cooling system refresh, including radiator and hoses, as plastics become brittle over two decades.
Prioritize high-quality synthetic engine oil changes every 5,000km to keep those turbochargers happy.
Regularly check the vacuum hoses in the engine bay, as the rubber can perish over time due to the high under-bonnet heat.
Keep the fuel system clean by using 98 octane petrol to prevent pre-detonation in the twin-turbo setup.
Inspect the CV joint boots for any tears or grease leaks to avoid premature axle failure.
Ensure your coolant is replaced with genuine Subaru Long Life coolant to protect the engine internals from internal corrosion.
Estimated repair costs if issues arise
If the previous owner hasn't provided documented proof, you'll want to plan for this immediately to ensure engine safety. This job involves replacing the belt, tensioner, and pulleys.
Given the age, the seals on the twin turbos might eventually show signs of wear. If you notice blue smoke or a drop in boost pressure, it's time to budget for professional testing or a rebuild.
The Legacy's handling is a highlight, but original struts and bushings may feel 'tired'. Replacing these with quality aftermarket or OEM parts will bring back that crisp steering feel.
