Installation & Conversion Notes

• Fuel Quality: To protect your VVEL system and ensure optimal power delivery, it is mandatory to use 93+ octane premium fuel. A professional ECU calibration is recommended to account for local fuel quality and altitude.

• Fluid System Care: Drain and replace all shipping fluids immediately. We recommend high-grade 5W-30 synthetic oil for the engine and a high-quality 75W-90 GL-4 gear oil for the 6-speed manual transmission to ensure smooth shifting.

• Maintenance Upgrade: Prior to final installation, it is considered industry best practice to install a new rear main seal, a fresh water pump, and a performance-grade clutch and flywheel assembly, as these are critical wear components that are difficult to access once the drivetrain is mounted.

• Cooling: Ensure your cooling system is flushed and functional, as the VQ37VHR is a high-thermal-efficiency engine that performs best with a high-capacity radiator and high-flow coolant.
