The A90 Supra, equipped with the B58 engine, has garnered significant attention for its performance potential. As enthusiasts push the limits of this platform, achieving over 650 horsepower becomes a common goal. However, reaching such power levels requires careful consideration of supporting modifications, particularly in the areas of transmission reinforcement and cooling system upgrades.
Importance of Supporting Mods
When increasing horsepower, it is crucial to ensure that the vehicle can handle the additional stress. Without proper supporting modifications, the risk of failure in key components rises dramatically. Two critical areas that require attention are the transmission and the cooling system.
Reinforced Transmission Options
The stock transmission in the A90 Supra is not designed to handle extreme power levels. To achieve reliable performance at 650+ horsepower, consider the following reinforcement options:
- Transmission Upgrade Kits: Various manufacturers offer kits that include stronger clutches, upgraded torque converters, and improved valve bodies.
- Aftermarket Transmission Controllers: These controllers can optimize shifting patterns and improve overall responsiveness.
- Strengthened Drivetrain Components: Upgrading driveshafts and differentials can help manage increased power and torque effectively.
Popular Transmission Brands
Several brands have made a name for themselves in the performance transmission market. Here are a few to consider:
- ShepTrans: Known for their high-performance transmission builds, ShepTrans offers a range of options for the A90 Supra.
- Pure Turbos: Their transmission upgrades focus on durability and performance, making them a popular choice among enthusiasts.
- Torque Solutions: They provide a variety of components aimed at enhancing the overall transmission performance.
Upgraded Cooling System
With increased horsepower comes the need for improved cooling. The stock cooling system may struggle to keep temperatures in check under high-performance conditions. Here are some essential upgrades:
- High-Performance Radiators: Upgrading to a larger, more efficient radiator can significantly improve cooling capacity.
- Oil Coolers: Adding an oil cooler helps maintain optimal oil temperatures, crucial for engine longevity.
- Upgraded Intercoolers: A larger intercooler reduces intake temperatures, improving performance and efficiency.
Cooling System Brands to Consider
When selecting components for your cooling system, consider these reputable brands:
- Mishimoto: Known for high-quality radiators and intercoolers, Mishimoto products are a favorite among performance enthusiasts.
- CSF Radiators: They offer a wide range of cooling solutions designed specifically for performance applications.
- Grimmspeed: Their products focus on enhancing cooling efficiency and performance reliability.
Conclusion
Achieving 650+ horsepower in the A90 Supra B58 requires careful planning and execution of supporting modifications. Reinforcing the transmission and upgrading the cooling system are essential steps to ensure reliability and performance. By investing in quality components and reputable brands, enthusiasts can enjoy the full potential of their high-powered Supra while minimizing the risk of failure.
