Installation & Technical Notes (EJ25 to EJ20 Swap)
To ensure a "plug-and-play" installation and satisfy your vehicle's ECU, you must perform the following component transfers from your original 2.5L engine:
-
Intake Manifold & Sensors: Transfer your original USDM intake manifold, fuel injectors, and wiring harness. This ensures all electrical plugs and vacuum lines match your vehicle exactly.
-
Crank & Cam Gears: You must swap your original USDM Crankshaft Sprocket and Left-Hand (Driver Side) Camshaft Sprocket. The JDM trigger points are often different; using your original gears ensures perfect ignition timing and prevents "Check Engine" lights.
-
Flex plate/Flywheel: Transfer your original flex plate (Automatic) or flywheel (Manual) to ensure the starter and transmission mate correctly.
-
Essential Maintenance: We strongly recommend replacing the following parts during the swap:
-
Timing Belt & Water Pump: Highly recommended while the engine is out.
-
Spark Plugs: NGK G-Power (BKR6EGP).
-
Oil Cooler/Filter Housing: Inspect for leaks and use a fresh Subaru OEM Blue filter.
-
Rear Main Seal: A low-cost part that is best replaced before the engine is mated to the transmission.
-
