The A90 Supra B58 is a remarkable vehicle, known for its impressive performance and tuning potential. However, when pushing the limits to 500+ horsepower, the fuel system must be optimized to ensure reliability and performance. In this article, we will explore the best fuel system modifications for the A90 Supra B58.
Understanding the Fuel System Needs
Before diving into specific modifications, it’s essential to understand the fuel system’s role in achieving high horsepower. The fuel system is responsible for delivering the correct amount of fuel to the engine, ensuring optimal combustion and performance.
- Fuel pumps
- Fuel injectors
- Fuel lines
- Fuel pressure regulators
Essential Modifications for Fuel System
Upgrading the Fuel Pump
The stock fuel pump may struggle to keep up with the demands of a tuned B58 engine. Upgrading to a high-performance fuel pump is crucial for maintaining fuel pressure and flow at higher power levels.
- Walbro 450 LPH Fuel Pump
- DeatschWerks DW300c
- Radium Engineering Fuel Pump Upgrade Kit
High-Flow Fuel Injectors
To accommodate the increased fuel demand, high-flow fuel injectors are necessary. These injectors ensure that the engine receives an adequate fuel supply, preventing lean conditions that can lead to engine damage.
- Injector Dynamics ID1050X
- FIC 1000cc Injectors
- DeatschWerks 1000cc Fuel Injectors
Upgrading Fuel Lines
As power levels increase, the stock fuel lines may not be sufficient to handle the higher flow rates. Upgrading to larger diameter fuel lines can help reduce restrictions and ensure consistent fuel delivery.
- AN-6 or AN-8 fuel lines
- Stainless steel braided lines
- Quality fuel fittings
Fuel Pressure Regulators
A fuel pressure regulator is vital for maintaining optimal fuel pressure under various engine loads. Upgrading to an adjustable fuel pressure regulator allows for fine-tuning, ensuring the engine receives the correct fuel pressure.
- AEM Adjustable Fuel Pressure Regulator
- Radium Engineering Fuel Pressure Regulator
- Fuel Lab Adjustable Regulator
Supporting Mods for Enhanced Performance
In addition to the primary fuel system modifications, several supporting mods can enhance overall performance and reliability.
- Upgraded intercooler
- High-performance air intake
- ECU tuning
Conclusion
Ensuring the reliability of the A90 Supra B58 at 500+ horsepower requires a well-thought-out approach to the fuel system. By upgrading the fuel pump, injectors, lines, and pressure regulators, enthusiasts can achieve their performance goals while maintaining engine safety and reliability.
