Installation & Technical Notes

The 8AR-FTS is a highly sophisticated engine utilizing both direct and port injection. To ensure a successful installation and maintain your warranty, please follow these technical guidelines:

 

• Long Block Conversion: This sale includes the engine block, cylinder head, and internal components. You must transfer your original USDM turbocharger assembly, intake manifold, exhaust manifold, and wiring harness to ensure 100% compatibility with your vehicle's ECU and vacuum system.

• D-4ST Fuel System: Retain your original high-pressure fuel pump and injectors from your USDM engine. This ensures the fuel maps remain calibrated correctly and prevents potential fueling errors.

• Turbo Cooling: The 8AR-FTS utilizes a complex water-cooling system for the integrated manifold. Ensure all coolant and oil feed lines to the turbocharger are flushed and free of debris before connecting them to this engine.

• Essential Maintenance: We strongly recommend replacing the following parts during the swap:

  • Spark Plugs: Use only OEM Lexus/Denso high-heat range turbo plugs (FK20HBR8).

  • Engine Oil: 0W-20 Full Synthetic oil only.

  • Coolant: Genuine Toyota/Lexus Pink Super Long Life Coolant.

• ECU Reset: After installation, a professional scan tool should be used to clear all adaptation values and perform a "Memory Reset" so the ECU can learn the new engine's parameters and timing curves.
