The Toyota A90 Supra has become a popular platform for car enthusiasts and tuners alike, particularly due to its powerful B58 inline-six engine. With the right modifications, it is possible to achieve over 700 horsepower, making it a formidable contender on both the street and the track. This article will explore the essential components and modifications needed to maximize the power output of the A90 Supra, focusing on methanol injection and upgraded fuel pumps.
Understanding the B58 Engine
The B58 engine is a 3.0-liter inline-six engine that features a twin-scroll turbocharger, making it capable of producing impressive power and torque figures. This engine is known for its robust construction and tuning potential, which is why many enthusiasts are eager to push its limits. To achieve 700+ horsepower, several key modifications are necessary.
Essential Modifications for 700+ HP
- Upgraded Turbocharger
- High-Performance Intercooler
- Enhanced Exhaust System
- Methanol Injection System
- Upgraded Fuel Pumps
- ECU Tuning
Upgraded Turbocharger
To reach 700+ horsepower, the stock turbocharger may not be sufficient. Upgrading to a larger turbocharger allows for increased airflow and boost pressure, which is essential for maximizing power. Popular options include the Pure Turbos and ETS turbo kits, which have been proven to support high horsepower builds.
High-Performance Intercooler
An upgraded intercooler is crucial for maintaining optimal intake temperatures. A larger, more efficient intercooler will help reduce heat soak, allowing the engine to maintain performance under load. Brands like Mishimoto and CSF offer high-performance options for the A90 Supra.
Enhanced Exhaust System
A free-flowing exhaust system is essential for reducing back pressure and improving engine efficiency. Upgrading to a cat-back exhaust system not only enhances sound but also contributes to increased horsepower. Look for systems from reputable manufacturers such as Akrapovic or Remus.
Methanol Injection System
Methanol injection is a game-changer when it comes to maximizing power. By injecting methanol into the intake, you can significantly increase the amount of fuel available for combustion, allowing for higher boost levels and preventing knock. Systems from Snow Performance or AEM are popular choices among tuners.
Upgraded Fuel Pumps
To support the increased fuel demands of a high-powered setup, upgrading the fuel pumps is critical. High-flow fuel pumps can ensure that the engine receives the necessary fuel at higher boost levels. Brands like Walbro and DeatschWerks offer reliable options for the A90 Supra.
ECU Tuning
After all the hardware modifications, proper ECU tuning is essential to unlock the full potential of the A90 Supra. A custom tune will optimize fuel maps, timing, and boost control to ensure that the engine runs smoothly and safely at high power levels. Tuning services from companies like EcuTek or Cobb Tuning are recommended.
Conclusion
Reaching 700+ horsepower on an A90 Supra B58 is an achievable goal with the right modifications. By upgrading the turbocharger, intercooler, exhaust system, and incorporating methanol injection along with upgraded fuel pumps, enthusiasts can unlock the true potential of this impressive engine. Remember, proper tuning is essential to ensure reliability and performance at these power levels. With dedication and the right parts, the A90 Supra can become a powerhouse on the road or track.
