The A90 Toyota Supra has gained a reputation for its impressive performance and tuning potential. With the B58 engine at its core, many enthusiasts are looking to push the limits of this powerhouse. In this article, we will explore how to build a 700 HP A90 Supra by upgrading to the Garrett GTX3076 turbocharger and reinforcing the fuel system.
Understanding the B58 Engine
The B58 engine is a 3.0-liter inline-six turbocharged engine that delivers a strong foundation for performance upgrades. It features a robust design, including an aluminum block and a forged steel crankshaft, making it capable of handling significant power increases.
Key Features of the B58 Engine
- Inline-six configuration for smooth power delivery.
- Single twin-scroll turbocharger for quick spool times.
- Direct and port fuel injection for improved efficiency.
Choosing the Right Turbo: Garrett GTX3076
The Garrett GTX3076 turbocharger is a popular choice among tuners looking to achieve high horsepower figures. Known for its efficiency and performance, this turbo can support power levels well beyond 700 HP.
Benefits of Upgrading to GTX3076
- Increased airflow for higher power potential.
- Better spool characteristics for improved throttle response.
- Durable construction for reliability under high boost conditions.
Reinforcing the Fuel System
To support the increased power output, it is crucial to upgrade the fuel system. The stock fuel system may not be adequate for 700 HP, necessitating the installation of high-flow fuel injectors and a more powerful fuel pump.
High-Flow Fuel Injectors
Upgrading to high-flow fuel injectors ensures that the engine receives the necessary fuel volume to match the increased air from the upgraded turbo. It is essential to choose injectors that can handle the power demands.
Upgraded Fuel Pump
An upgraded fuel pump is vital for maintaining the correct fuel pressure under high load. A pump capable of delivering sufficient fuel at higher flow rates will prevent lean conditions, which can be detrimental to engine health.
Tuning the A90 Supra
After installing the Garrett GTX3076 turbo and reinforcing the fuel system, proper tuning is essential to maximize performance and ensure reliability. A professional tuner can adjust the engine’s parameters to optimize power delivery and efficiency.
Importance of Custom Tuning
Custom tuning allows for adjustments based on the specific modifications made to the vehicle. This ensures that the engine runs smoothly and efficiently, reducing the risk of damage from improper air-fuel ratios.
Conclusion
Building a 700 HP A90 Supra B58 requires careful consideration of upgrades, particularly when it comes to the turbocharger and fuel system. By choosing the Garrett GTX3076 and reinforcing the fuel system, enthusiasts can unlock the full potential of this impressive engine. With the right tuning, the A90 Supra can deliver exhilarating performance on the road and track.
