The Mitsubishi Lancer Evolution, commonly known as the Evo, has earned a legendary status among car enthusiasts and tuners alike. With its turbocharged engine and all-wheel-drive system, the Evo is known for its performance capabilities. However, many enthusiasts seek to push the limits of power and performance even further. In this article, we will explore the power gains achievable through a turbo upgrade and upgraded internals, taking the Evo from stock power levels to an impressive 500+ horsepower.
Understanding the Stock Evo Performance
The stock Mitsubishi Lancer Evolution comes equipped with a turbocharged inline-four engine. Depending on the model year, the stock horsepower typically ranges from 250 to 300 hp. While this power level is impressive for most drivers, serious enthusiasts often find themselves craving more performance.
Benefits of Turbo Upgrades
Upgrading the turbocharger is one of the most effective ways to increase horsepower. A larger turbo can deliver more air to the engine, allowing for greater fuel combustion and, consequently, more power. Here are some benefits of turbo upgrades:
- Increased horsepower and torque
- Improved throttle response
- Higher boost levels
- Enhanced engine efficiency
Choosing the Right Turbocharger
When selecting a turbocharger for your Evo, it’s crucial to choose one that matches your power goals. Popular options include:
- Garrett GTX3071R
- Precision 6266
- FP Black Turbo
Upgrading Engine Internals
To safely achieve 500+ horsepower, upgrading the engine internals is essential. Stock internals may not withstand the increased power and boost levels. Here are some key components to consider upgrading:
- Pistons
- Connecting rods
- Cylinder head
- Valves and springs
Pistons and Connecting Rods
High-performance pistons and connecting rods are vital for handling increased power. Forged components are recommended for their strength and durability. They can withstand higher boost levels and extreme conditions, reducing the risk of engine failure.
Upgrading the Cylinder Head
The cylinder head plays a critical role in airflow and combustion efficiency. Upgrading to a higher-flow cylinder head can significantly improve performance by allowing for better air intake and exhaust flow. Porting and polishing the head can also enhance these benefits.
Tuning for Maximum Performance
After upgrading the turbo and engine internals, proper tuning is essential to unlock the full potential of your Evo. A professional tune will ensure that the air-fuel mixture is optimized for the new components, maximizing power while maintaining reliability.
Choosing a Tuner
Selecting a reputable tuner is crucial for achieving the desired power gains. Look for tuners with experience in Evo builds and a proven track record. They should provide dyno tuning services to ensure accurate performance measurements.
Potential Challenges and Considerations
While the prospect of achieving 500+ horsepower is exciting, it’s essential to consider potential challenges. Increased power can lead to:
- Increased wear on engine components
- Higher maintenance requirements
- Potential for drivetrain stress
- Insurance and legality issues
Maintaining Reliability
To maintain reliability with an upgraded Evo, regular maintenance is crucial. This includes:
- Frequent oil changes
- Monitoring boost levels
- Inspecting engine components regularly
Conclusion
Upgrading your Mitsubishi Lancer Evolution’s turbo and internals can lead to impressive power gains, pushing the limits to 500+ horsepower. With the right components and tuning, you can transform your Evo into a high-performance machine. However, it’s essential to approach these upgrades with caution and ensure that all components work harmoniously to maintain reliability and performance.
