The Toyota A90 Supra B58 has captured the hearts of car enthusiasts with its sleek design and powerful engine. With a stock horsepower of around 335, many owners are looking to push their vehicles to the next level. This article will explore the top intake, exhaust, and intercooler support modifications that can help you achieve 450 horsepower.
Understanding the B58 Engine
The B58 engine is a 3.0-liter inline-six turbocharged engine that is known for its smooth power delivery and tuning potential. This engine is part of BMW’s modular engine family and shares components with other successful engines. Understanding its strengths and weaknesses is crucial for making effective modifications.
Top Intake Modifications
Improving airflow into the engine is essential for increasing horsepower. Here are some top intake modifications for the A90 Supra B58:
- Cold Air Intake System: Upgrading to a cold air intake system can significantly enhance airflow, resulting in better throttle response and increased power.
- High-Performance Air Filter: Replacing the stock air filter with a high-performance variant can improve filtration while allowing more air to flow into the engine.
- Intake Manifold Upgrade: Consider upgrading the intake manifold for improved airflow distribution and performance gains.
Exhaust Modifications for Maximum Power
An efficient exhaust system is critical for maximizing power output. Here are some recommended exhaust modifications:
- Cat-Back Exhaust System: Upgrading to a cat-back exhaust system can reduce back pressure and improve exhaust flow, leading to increased horsepower.
- High-Flow Catalytic Converter: A high-flow catalytic converter can provide better exhaust flow while maintaining emissions compliance.
- Headers: Installing aftermarket headers can significantly improve exhaust scavenging and overall performance.
Enhancing Intercooler Performance
The intercooler plays a vital role in cooling the intake air, which is crucial for performance. Here are some modifications to consider:
- Upgraded Front Mount Intercooler: A larger front mount intercooler can provide better cooling efficiency, allowing for denser air to enter the engine.
- Intercooler Piping Upgrade: Replacing the stock intercooler piping with larger, smoother pipes can reduce turbulence and improve airflow.
- Water/Methanol Injection: Consider adding a water/methanol injection system to further reduce intake temperatures and increase power.
Tuning for Optimal Performance
After making these modifications, tuning the engine is essential to unlock the full potential of your A90 Supra B58. A professional tune can adjust fuel maps, ignition timing, and boost levels to ensure optimal performance and reliability.
Conclusion
Building a 450 horsepower A90 Supra B58 is an exciting journey that requires careful planning and execution. By focusing on intake, exhaust, and intercooler modifications, along with proper tuning, you can achieve your performance goals while enjoying the thrill of driving one of the most iconic sports cars on the market.
