Engineering of the 1998 Subaru Impreza WRX STI
Under the skin, the 1998 STI relied on the EJ207, a 2.0-liter turbocharged boxer with forged components and a closed-loop boost system. Symmetrical all-wheel delivery and a short wheelbase translated into precise turn-in and confident cornering, hallmarks of Subaru’s motorsport background.

Externally, the 1998 STI was distinguished by larger bumpers, a subtle rear spoiler, and specific wheels that hinted at its rally pedigree. Inside, the cabin balanced race-inspired details with practical visibility, making it viable for spirited back-road drives as well as occasional track days.
Maintaining and Owning a 1998 STI

Original equipment tires and alignment settings were tailored for the era’s grip levels, so upgrading to modern rubber can improve safety without compromising the responsive chassis behavior. Keeping an eye on boost leaks and intercooler integrity is especially important for cars that have covered high mileage.
