As an enthusiast, you understand the importance of proper engine cooling. The ’96 Supra Twin Turbo, with its twin-turbocharged 2JZ-GTE engine, generates immense heat during high-performance drives. Here are six tips to maximize cooling and keep your engine running smoothly:

  1. Upgrade Radiator and Fans: Start by replacing your stock radiator with a high-performance aluminum radiator. Aluminum radiators offer superior heat dissipation and are more efficient than their stock counterparts. Additionally, consider installing high-flow electric fans for enhanced airflow, ensuring better cooling efficiency.

  2. Optimize Airflow: Improving airflow to the radiator is crucial for efficient cooling. Make sure the front grille is clean and not obstructed by dirt or debris. You can also opt for a vented hood or add hood vents to improve airflow and reduce engine bay heat buildup.

  3. Upgrade Coolant and Water Pump: Switch to a high-performance coolant specifically designed for turbocharged engines. This coolant will have a higher boiling point and better heat transfer properties. Upgrading the water pump to a high-flow unit will also aid in circulating coolant efficiently, keeping temperatures in check.

  4. Invest in a Thermostat: Consider upgrading to a low-temperature thermostat. This modification allows coolant to flow through the engine at lower temperatures, helping to prevent overheating during intense driving conditions.

  5. Upgrade Intercooler and Piping: As the Supra Twin Turbo’s engine generates more power, the stock intercooler might struggle to keep up. Upgrading to a larger intercooler with better cooling efficiency will help lower intake air temperatures, resulting in improved engine performance and reliability. Replace the intercooler piping with larger diameter pipes to reduce pressure drop and improve airflow.

  6. Add an Oil Cooler: High-performance driving puts a significant strain on the engine oil, leading to increased temperatures. Installing an oil cooler will help dissipate that heat and maintain optimal oil temperature, reducing the risk of engine damage.
