The Toyota Supra is a legendary sports car known for its performance and tuning potential. For enthusiasts looking to push the limits and reach over 700 horsepower, modifications to the turbocharger and fuel system are essential. In this article, we will explore the necessary steps and components to achieve this power goal.
Understanding the Toyota Supra
The Toyota Supra, particularly the A80 model produced from 1993 to 2002, has gained a cult following due to its robust 2JZ engine. This inline-six engine is renowned for its durability and tuning capabilities, making it a favorite among car enthusiasts.
Turbocharger Upgrades
One of the most effective ways to increase horsepower in your Supra is by upgrading the turbocharger. A larger turbo can provide more airflow, which is crucial for achieving higher power levels.
Choosing the Right Turbocharger
When selecting a turbocharger, consider the following factors:
- Size: A larger turbo will support higher horsepower but may introduce lag.
- Type: Consider twin-scroll or single turbo options based on your power goals.
- Brand: Popular brands include Garrett, BorgWarner, and Precision Turbo.
Installation Considerations
Proper installation is crucial for maximizing the performance of your new turbocharger. Ensure that the following steps are taken:
- Use high-quality gaskets and seals to prevent leaks.
- Upgrade the intercooler to handle increased airflow.
- Consider a turbo manifold that enhances exhaust flow.
Fuel System Modifications
To support the increased airflow from a larger turbo, modifications to the fuel system are necessary. This includes upgrading the fuel pump, injectors, and potentially the fuel lines.
Upgrading the Fuel Pump
A high-performance fuel pump is essential for delivering the necessary fuel volume and pressure to the engine. Consider the following options:
- Brand: Look for reputable brands like Walbro or AEM.
- Flow Rate: Ensure the pump can support your horsepower goals.
Injectors and Fuel Lines
Upgrading the fuel injectors is crucial to ensure that the engine receives the right amount of fuel. Look for injectors that can handle the power you aim to achieve:
- Size: Consider injectors rated for at least 1000cc/min for 700+ hp.
- Type: High-impedance injectors are typically recommended for the Supra.
Additionally, consider upgrading the fuel lines to ensure they can handle the increased pressure and volume required by the new fuel pump and injectors.
Tuning Your Supra
After completing the turbocharger and fuel system upgrades, proper tuning is essential to ensure that your Supra runs efficiently and safely. A professional tune can help you achieve optimal performance and reliability.
Choosing a Tuner
Select a tuner with experience in high-performance applications, particularly with the Toyota Supra. Look for tuners who utilize advanced software and have a reputation for delivering reliable results.
Tuning Process
The tuning process typically involves:
- Baseline dyno run to measure current horsepower and torque.
- Adjusting fuel maps and ignition timing for optimal performance.
- Final dyno run to confirm the power output and make any necessary adjustments.
Conclusion
Reaching 700+ horsepower in your Toyota Supra is an achievable goal with the right modifications to the turbocharger and fuel system. By carefully selecting components and ensuring proper installation and tuning, you can unlock the full potential of your Supra and enjoy an exhilarating driving experience.
