Intercooler Type:
Top-mounted air-to-air intercooler
Oil Change:
Every 3,000-5,000 miles or 3-6 months, depending on driving conditions.
Timing Belt:
Replace every 60,000-100,000 miles or 7-10 years (critical component).
Engine Oil:
API SG or higher, SAE 10W-30 or 10W-40 recommended (consult manual for exact specs).
Coolant:
Subaru Super Coolant or equivalent ethylene glycol-based coolant.
Transmission Fluid Manual:
API GL-5, SAE 75W-90 synthetic gear oil.
Differential Fluid Front:
API GL-5, SAE 75W-90 synthetic gear oil.
Differential Fluid Rear:
API GL-5, SAE 75W-90 synthetic gear oil (check for limited-slip if applicable).
Engine Head Gaskets:
While more prevalent in later naturally aspirated models, early EJ20G engines can experience head gasket issues with age and high performance use.
Turbocharger Wear:
Turbocharger can experience wear over time, especially with improper maintenance or abuse. Oil leaks and loss of boost are common symptoms.
Clutch Wear:
Performance driving can lead to accelerated clutch wear.
Suspension Bushings:
Rubber bushings in suspension and drivetrain can degrade over time, leading to noise and poor handling.
