Description

Torque Solution Big Bore 76mm Throttle Body Adapter for Subaru EJ engines using a big bore intake manifold. Our adapter allows you to swap to a Toyota 76mm big bore throttle body which provides a 25% increase in size over OEM. Made from CNC billet aluminum that we anodize for corrosion resistance, provide o-ring gaskets for a leak free seal, and all the necessary hardware to complete the install.

  • Important Install Notes:
    • Intended for high HP builds.
    • First consult with your tuner to ensure they will be able to make this TB setup work for you.

    • Must have FMIC piping (piping modification may be necessary).
    • You will need a new transition coupler and clamp to fit the big bore TB (3.5") to your piping.
    • You will need an aftermarket MAP sensor and relocate it to the intake manifold or a vacuum block.
