Character

EJ20 Turbo

"WRX/STI legend. Unequal-length headers = boxer rumble. Head gasket concerns. Maintenance-intensive but rewarding."

EJ20 NA

"Impreza/Forester NA. Head gasket failure is THE Subaru issue (external leak). Oil consumption. Timing belt (interference). Strong with care. Replace head gaskets proactively."
