Installation & Notes

• USDM Conversion: Use as long block and must transfer your original USDM intake & exhaust manifolds, coil packs, spark plugs, fuel rail, wiring harness and all sensors to this JDM unit to ensure 100% ECU compatibility.

• EGR Port: Some JDM units lack the EGR port on the driver-side head; you may need to perform a simple block-off modification.

• Maintenance: We highly recommend a new timing belt kit, water pump, and spark plugs prior to installation.

• Oil: Use 5W-30 Full Synthetic Motor Oil.
