The Mitsubishi Lancer Evolution VIII, commonly known as the Evo 8, is a high-performance vehicle that has gained a cult following among car enthusiasts. One of the most effective ways to enhance the performance of the Evo 8 is through an intake and exhaust combo. In this article, we will explore how you can achieve over 70 horsepower gains with just $1,200 in parts.
Understanding the Evo 8 Engine
The Evo 8 is powered by a 2.0-liter turbocharged inline-four engine, known as the 4G63. This engine is renowned for its tuning potential and can handle significant power increases with the right modifications. To maximize the performance of this engine, it is essential to focus on improving airflow, both into and out of the engine.
Benefits of an Intake and Exhaust Combo
Installing an upgraded intake and exhaust system offers several benefits:
- Increased Airflow: A performance intake allows for better air intake, while a high-flow exhaust reduces back pressure, enabling the engine to breathe more freely.
- Improved Throttle Response: Enhanced airflow leads to quicker throttle response, making the car feel more agile and responsive.
- Weight Reduction: Aftermarket exhaust systems are often lighter than stock systems, contributing to an overall reduction in vehicle weight.
- Sound Enhancement: A performance exhaust produces a more aggressive sound, enhancing the driving experience.
Recommended Parts for the Evo 8 Intake and Exhaust Combo
To achieve significant horsepower gains, consider the following parts:
- Intake System: Look for a quality cold air intake system, such as the Injen SP Series or the AEM Cold Air Intake. These systems typically range from $250 to $400.
- Exhaust System: A cat-back exhaust system, like the Greddy or HKS, is recommended for optimal performance. Expect to pay between $600 and $800.
- High-Flow Catalytic Converter: If your budget allows, consider adding a high-flow cat for better performance. These can range from $200 to $300.
Installation Process
Installing the intake and exhaust systems can be done at home with basic tools. Here’s a brief overview of the installation process:
- Gather Tools: You will need basic hand tools, including wrenches, sockets, and screwdrivers.
- Remove Stock Intake: Disconnect the battery, remove the stock intake system, and install the new intake according to the manufacturer’s instructions.
- Install Exhaust System: Remove the stock exhaust system starting from the rear. Install the new cat-back exhaust, ensuring all connections are secure.
- Check for Leaks: After installation, check for any exhaust leaks and ensure all components are tightly secured.
Tuning for Maximum Gains
After installing the intake and exhaust, it is crucial to tune the vehicle to achieve the best performance. A proper tune can optimize air-fuel ratios and ignition timing, maximizing horsepower gains. Consider the following options:
- ECU Reflash: A reflash of the factory ECU can improve performance without needing additional hardware.
- Standalone Engine Management: For those looking for more control, a standalone system like the AEM Infinity or Haltech can provide extensive tuning options.
- Dyno Tuning: Having your Evo 8 tuned on a dynamometer ensures that you achieve the best possible performance from your modifications.
Expected Results
With the right intake and exhaust combo, along with a proper tune, you can expect to see gains of 70+ horsepower. This increase can significantly enhance your driving experience, making your Evo 8 more enjoyable and responsive on the road or track.
Conclusion
The Evo 8 is a fantastic platform for performance modifications, and an intake and exhaust combo is one of the best ways to unlock its potential. By investing approximately $1,200 in quality parts and ensuring a proper installation and tuning, you can achieve impressive horsepower gains that elevate your driving experience to the next level.
