The A90 Supra has garnered a reputation for its impressive performance and sleek design. However, to unlock the full potential of this sports car, upgrading the intercooler is essential. An upgraded intercooler can enhance power output and improve reliability, especially under demanding conditions.
Understanding the Intercooler
An intercooler is a crucial component in forced induction systems. It cools the air entering the engine after it has been compressed by the turbocharger. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which can lead to increased power and efficiency.
Benefits of Upgrading the A90 Supra Intercooler
Upgrading the intercooler on the A90 Supra can provide several advantages:
- Increased Power Output: A larger intercooler can significantly improve power by reducing intake temperatures.
- Improved Reliability: Better cooling helps prevent engine knock and reduces the risk of overheating.
- Enhanced Performance: Consistent performance under various driving conditions, including track days and spirited driving.
- Better Tuning Potential: Allows for more aggressive tuning options without the risk of damaging the engine.
Choosing the Right Intercooler
When selecting an intercooler for the A90 Supra, consider the following factors:
- Core Size: A larger core size can improve cooling efficiency but may require modifications for fitment.
- Material: Look for intercoolers made from high-quality materials like aluminum for better heat dissipation.
- End Tank Design: Efficient end tank designs can improve airflow and reduce pressure drop.
- Brand Reputation: Choose reputable brands known for quality and performance in the automotive community.
Installation Process
Installing an upgraded intercooler on the A90 Supra can be a straightforward process with the right tools and knowledge. Here’s a general overview of the steps involved:
- Gather Tools and Materials: Ensure you have all necessary tools, including sockets, wrenches, and clamps.
- Remove the Front Bumper: This may be necessary to access the intercooler and ensure a clean installation.
- Disconnect the Old Intercooler: Carefully detach any hoses and clamps connected to the stock intercooler.
- Install the New Intercooler: Position the new intercooler in place and secure it with the provided hardware.
- Reconnect Hoses: Ensure all hoses are reconnected securely to prevent any boost leaks.
- Reinstall the Front Bumper: Once everything is in place, reattach the front bumper and ensure proper fitment.
Tuning After Installation
After upgrading the intercooler, it’s crucial to tune the engine to take full advantage of the new setup. A proper tune can optimize air-fuel ratios and ignition timing, resulting in improved performance and reliability.
- ECU Remapping: Consider remapping the ECU to accommodate the increased airflow and cooler intake temperatures.
- Dyno Tuning: A dyno session can help fine-tune the vehicle’s performance and ensure everything is running smoothly.
- Monitoring: Use gauges or an OBD-II scanner to monitor engine parameters and ensure safe operating conditions.
Common Issues and Solutions
While upgrading the intercooler can provide numerous benefits, some common issues may arise:
- Boost Leaks: Ensure all connections are tight and check for leaks after installation.
- Fitment Issues: If the intercooler doesn’t fit properly, additional modifications may be required.
- Increased Turbo Lag: A larger intercooler may introduce some turbo lag; tuning can help mitigate this.
Conclusion
Upgrading the A90 Supra intercooler is a worthwhile investment for those looking to enhance performance and reliability. With the right intercooler, installation process, and tuning, drivers can unlock the full potential of their vehicle, ensuring a thrilling driving experience for years to come.
