Tomei Subaru Impreza WRX (94-20) & WRX STI (94-07) EJ20 & EJ25 Single Scroll MX7960F Journal Bearing Turbocharger with Billet Actuator

Introducing the Tomei Arms Mx7960F Turbocharger, a pinnacle of engineering excellence designed for the Subaru EJ20 and EJ25 platforms. This turbocharger is not merely an upgrade; it represents a meticulous evolution of Tomei's original M-Series design, integrating cutting-edge technology and premium materials to deliver unparalleled performance and reliability.

Design & Engineering
At the heart of the Mx7960F is a newly engineered billet compressor wheel, crafted from aerospace-grade A261 aluminium. This innovative component features thinner blades and a larger surface area, resulting in significantly enhanced airflow and rapid turbo spool. The transition from traditional cast wheels to this advanced billet design marks a notable leap forward in turbocharger efficiency and responsiveness.

Multi-Range Billet Actuator
The turbocharger is equipped with a large-capacity multi-rate billet actuator, constructed from reinforced forged billet material. This actuator includes six springs for precise boost adjustments, allowing the user to customize their setup by combining up to three springs for optimal performance. The swivel-type nipple further enhances flexibility in hose routing, ensuring a clean and efficient installation.
