Mitsubishi Lancer Evolution: A Comprehensive Guide
The Mitsubishi Lancer Evolution, commonly known as the "Evo," is a high-performance sedan with a rich rally heritage. This guide covers its history, common issues, and tuning potential.
History & Evolution
The Lancer Evolution was produced from 1992 to 2016, with ten generations in total. Each generation brought significant improvements in performance and technology, solidifying the Evo's legendary status.
- Evo I-III (1992-1996): The early Evos established the formula with a turbocharged 2.0L 4G63T engine and all-wheel drive.
- Evo IV-VI (1996-2001): These models introduced Active Yaw Control (AYC) and further refined the platform's handling and performance.
- Evo VII-IX (2001-2007): The Evo received a new chassis and significant technological upgrades, including an active center differential (ACD).
- Evo X (2007-2016): The final generation of the Evo featured a new aluminum 4B11T engine and a dual-clutch transmission option.
Common Issues
While the Evo is a robust platform, it has some common issues to be aware of:
- Timing Chain Stretch: The 4B11T engine in the Evo X is known for timing chain stretch, which can be prevented with regular oil changes.
- Overheating: The Evo's high-performance nature can lead to overheating, especially when modified. Upgraded cooling systems are a common modification.
- Transfer Case Issues: The all-wheel-drive system can be a weak point, with transfer case failures being a known issue.
- Rust: Like many Japanese cars of its era, the Evo can be prone to rust, especially in the rear quarter panels and underbody.
Performance Tuning
The Evo is a tuner's dream, with a massive aftermarket and endless tuning potential. Common modifications include:
- ECU Tuning: A custom tune is the best way to unlock the Evo's full potential.
- Upgraded Turbocharger: A larger turbo can significantly increase horsepower and torque.
- Fuel System Upgrades: Upgraded fuel injectors and a high-flow fuel pump are necessary for supporting higher power levels.
- Exhaust and Intake: A full exhaust system and cold air intake are essential for improving airflow and maximizing performance.
