The SW20 MR2 Turbo is a beloved sports car known for its mid-engine layout and agile handling. One of the most effective ways to enhance its performance is by upgrading to a 3-inch OEM turbo exhaust system. This modification can yield significant horsepower gains, often cited around 30 HP, making it a popular choice among enthusiasts.
Why Upgrade to a 3-Inch Exhaust?
Upgrading to a 3-inch exhaust system offers several advantages that contribute to improved engine performance:
- Increased Flow: A larger diameter exhaust allows for better exhaust gas flow, reducing back pressure.
- Enhanced Turbo Response: Improved flow can lead to quicker turbo spool times, increasing overall efficiency.
- Sound Improvement: A 3-inch exhaust can provide a deeper, more aggressive exhaust note.
Key Features of a 3-Inch OEM Turbo Exhaust
The 3-inch OEM turbo exhaust is designed with specific features that cater to performance and durability:
- High-Quality Materials: Typically made from stainless steel, ensuring longevity and resistance to corrosion.
- Precision Engineering: Designed to fit the SW20 MR2 Turbo perfectly, minimizing installation issues.
- Optimized Design: Features such as mandrel bends help maintain exhaust flow efficiency.
Installation Process
Installing a 3-inch OEM turbo exhaust may require some mechanical knowledge and tools. Here’s a basic overview of the installation process:
- Gather Tools: You will need basic hand tools, a jack, and jack stands.
- Remove the Old Exhaust: Start by safely lifting the vehicle and removing the existing exhaust system.
- Install the New Exhaust: Position the new 3-inch exhaust and secure it in place, ensuring all connections are tight.
- Check for Leaks: Once installed, start the engine and check for any exhaust leaks.
Performance Gains
Upgrading to a 3-inch OEM turbo exhaust can lead to substantial performance improvements. Here are some expected gains:
- Horsepower Increase: Many users report gains of up to 30 HP, depending on other modifications.
- Torque Improvement: Enhanced torque delivery can improve acceleration and overall drivability.
- Better Fuel Efficiency: Improved exhaust flow can lead to better fuel economy under certain driving conditions.
Considerations Before Upgrading
Before proceeding with the upgrade, consider the following factors:
- Budget: Ensure you have allocated enough funds not only for the exhaust but also for potential installation costs.
- Compatibility: Confirm that the exhaust is compatible with your specific MR2 model and year.
- Other Modifications: Consider whether you have or plan to make other performance modifications that may influence exhaust choice.
Conclusion
