JDM to USDM Installation & Swap Guide

To ensure 100% compatibility and a "Plug-and-Play" installation into your USDM Legacy, professional installers must follow these "External Swap" steps:

  1. Intake, Exhaust Manifold & Sensors: You must swap your original USDM Intake, Exhaust Manifold, PCV Valve and all sensors (MAP, TPS, etc.) onto the JDM block. JDM wiring plugs often differ from US-spec harnesses.

  2. AVCS Solenoids: Ensure the JDM AVCS solenoids match your USDM plugs; if they differ, transfer your original USDM solenoids to the JDM heads.

  3. Wiring Harness: Always retain and use your vehicle's original USDM Engine Wiring Harness.

  4. Water Crossover Pipe: Inspect the coolant pipe and thermostat housing; if the angles differ, swap your USDM components to ensure your radiator hoses fit correctly.
