The Toyota A90 Supra has garnered a reputation for its impressive performance and sleek design. However, for enthusiasts looking to boost their horsepower without breaking the bank, there are several cost-effective upgrades available. In this article, we will explore performance upgrades for the A90 Supra that can be achieved for under $2,000, each capable of adding 100+ horsepower.
1. ECU Tune
One of the most effective and simplest ways to increase horsepower is through an ECU (Engine Control Unit) tune. This upgrade optimizes the engine’s performance parameters, allowing for a significant boost in power.
- Cost: Approximately $500 – $1,000
- HP Gain: 50 – 100 HP
- Notes: Ensure the tune is designed specifically for the A90 Supra and consider professional installation for best results.
2. Cold Air Intake System
A cold air intake system helps improve airflow to the engine, which can enhance performance and efficiency. By replacing the stock air intake with a high-performance system, you can expect noticeable gains.
- Cost: Approximately $300 – $600
- HP Gain: 10 – 20 HP
- Notes: Look for reputable brands that offer quality materials and filtration.
3. High-Performance Exhaust System
Upgrading the exhaust system can significantly reduce back pressure and improve exhaust flow. A high-performance exhaust not only enhances horsepower but also gives the car a more aggressive sound.
- Cost: Approximately $800 – $1,500
- HP Gain: 15 – 25 HP
- Notes: Consider a cat-back system for the best results and sound.
4. Upgraded Intercooler
An upgraded intercooler can provide better cooling for the intake air, which is crucial for maintaining performance, especially during high-load conditions. This upgrade can help prevent heat soak and improve overall efficiency.
- Cost: Approximately $600 – $1,200
- HP Gain: 20 – 40 HP
- Notes: Ensure compatibility with your existing setup and consider professional installation.
5. Lightweight Wheels
While not a direct horsepower gain, upgrading to lightweight wheels can significantly improve acceleration and handling. Reducing unsprung weight allows the vehicle to respond better and can enhance driving dynamics.
- Cost: Approximately $800 – $1,500
- HP Gain: Indirect performance improvement
- Notes: Look for reputable brands that focus on performance and durability.
6. Performance Spark Plugs
Upgrading to performance spark plugs can improve combustion efficiency and throttle response. This simple upgrade can enhance the overall performance of the engine.
- Cost: Approximately $100 – $200
- HP Gain: 5 – 10 HP
- Notes: Choose plugs that are designed for high-performance applications.
Conclusion
With these cost-effective performance upgrades, A90 Supra owners can achieve significant horsepower gains without exceeding a $2,000 budget. From ECU tunes to exhaust systems, each upgrade contributes to a more powerful and enjoyable driving experience. Always consider professional installation and quality parts to ensure the best results and longevity of your upgrades.
