JDM to USDM Long Block Installation Notes

To ensure a seamless swap and prevent Check Engine Lights (CEL), follow these critical conversion steps using components from your original USDM engine:

1. Cam Gear Trigger Plates: Crucial Step. You must swap the trigger plates on the cam phasers from your USDM engine to the JDM engine. The JDM pattern is different and will cause timing/sync errors if left as-is.
2. Oil Pan & Level Sensor: JDM FA20DITs often lack the oil level sensor found in USDM WRXs. Swap your USDM upper and lower oil pans to maintain your oil level warning system.
3. Engine Wiring Harness: Always reuse your original USDM wiring harness. JDM connectors for the alternator and various sensors may differ.
4. Intake Manifold & Sensors: Transfer your USDM intake manifold, TGV (Tumble Generator Valve) assemblies, and all sensors (MAP, MAF, etc.) to the JDM long block.
5. Turbo & Accessories: Reuse your USDM turbocharger, intercooler, and alternator if they are in good condition, as JDM mounting points or electrical plugs can vary slightly by year.
