The A90 Supra has gained significant attention among car enthusiasts and tuners for its performance potential. One of the most effective ways to enhance the power output of this vehicle is through aftermarket modifications, particularly camshafts and fuel systems. In this article, we will compare various aftermarket camshafts and fuel systems available for the A90 Supra, focusing on how these components can maximize power.
Understanding Camshaft Functionality
Camshafts play a crucial role in the engine’s performance by controlling the timing and amount of air and fuel that enters the combustion chamber. The design of the camshaft can significantly influence engine characteristics such as torque and horsepower. In the A90 Supra, upgrading the camshaft can lead to improved engine breathing, which is essential for maximizing power.
Types of Aftermarket Camshafts
- Performance Camshafts: Designed for higher RPM performance, these camshafts increase lift and duration to enhance airflow.
- Stage 1 Camshafts: Ideal for daily drivers, these camshafts provide a balance of performance and drivability.
- Stage 2 and 3 Camshafts: These options are tailored for high-performance builds, focusing on maximizing horsepower at the expense of some low-end torque.
Choosing the right camshaft depends on the intended use of the vehicle. For those looking to maximize power, a performance camshaft that suits the overall build is essential.
Fuel System Upgrades
The fuel system is another critical component when it comes to achieving maximum power in the A90 Supra. Upgrading the fuel system ensures that the engine receives the necessary fuel supply to support increased power levels from modifications like camshaft upgrades.
Components of an Upgraded Fuel System
- Fuel Injectors: High-flow fuel injectors can deliver more fuel to the engine, which is essential for higher horsepower levels.
- Fuel Pump: An upgraded fuel pump is necessary to maintain proper fuel pressure, especially under high-performance conditions.
- Fuel Lines: Larger diameter fuel lines can reduce restrictions and improve fuel flow to the engine.
When upgrading the fuel system, it is vital to ensure compatibility with the engine’s modifications. Proper tuning is also necessary to optimize performance and prevent engine damage.
Comparing Aftermarket Options
Now that we understand the importance of camshafts and fuel systems, let’s compare some popular aftermarket options available for the A90 Supra.
Aftermarket Camshaft Options
- BC Racing Camshafts: Known for their aggressive profiles, these camshafts provide significant power gains at higher RPMs.
- HKS Camshafts: HKS offers a range of camshafts designed for both street and track applications, providing a good balance of performance and drivability.
- GSC Power-Division Camshafts: These camshafts are designed for high-performance builds, focusing on maximizing airflow and power output.
Each of these options has its unique characteristics and benefits, making it crucial to choose one that aligns with your performance goals.

Integrating Camshafts and Fuel Systems
For maximum power gains, it’s essential to integrate both camshaft and fuel system upgrades effectively. The synergy between these components can lead to optimal performance and efficiency.
Tuning for Performance
After installing aftermarket camshafts and fuel systems, proper tuning is critical. This ensures that the engine runs efficiently and can handle the increased airflow and fuel delivery. A professional tune can help achieve the best performance results, maximizing power output while maintaining reliability.
Common Mistakes to Avoid
- Neglecting Tuning: Failing to tune the engine after modifications can lead to poor performance and potential engine damage.
- Overlooking Supporting Mods: Upgrading camshafts and fuel systems without considering other supporting modifications can limit performance gains.
- Choosing Incompatible Parts: Always ensure that components are compatible with each other to avoid issues during installation and operation.
By avoiding these common pitfalls, you can ensure that your A90 Supra performs at its best with the new upgrades.
Conclusion
In conclusion, upgrading the camshaft and fuel system of the A90 Supra can significantly enhance its power and performance. By carefully selecting aftermarket options and ensuring proper integration and tuning, enthusiasts can unlock the full potential of their vehicles. Whether you’re aiming for daily drivability or track-ready performance, the right combination of camshafts and fuel systems will make all the difference.
