A stock-location, bolt-on journal bearing turbo meticulously developed over three years for EJ series engines. Designed for quick response and strong mid-range power. It produced 440 WHP and 460 WTQ on a Stage 3 2020 STI with tuning and fuel upgrades, an increase of 70 HP and 66 WTQ over a tuned stock turbo STI. Ideal for performance daily drivers and track-dedicated race cars.
