4G63 Engine

Specifications

The Mitsubishi 4G63 engine is a legendary 2.0L turbocharged inline-4 engine built for performance, durability, and serious tuning potential. It features a strong cast-iron block paired with an aluminum DOHC 16-valve head, designed to handle high boost and demanding driving conditions with ease. In stock form, it produces around 190–280+ horsepower and 200–290 lb-ft of torque depending on the application, making it a proven performer across multiple generations of Mitsubishi’s performance lineup.

Used in iconic models like the Lancer Evolution I–IX, Eclipse GSX, Eagle Talon TSi, and Galant VR-4, the 4G63 is well known for its rally heritage and long-lasting reliability. It comes equipped with a turbocharged setup, efficient cooling features like oil squirters, and in many versions, strengthened internal components for added durability. What truly sets it apart is its exceptional tuning capability—supporting high horsepower builds with ease, often reaching 500–800 wheel horsepower in modified setups and even beyond 1,000 horsepower in extreme builds. The 4G63T remains one of the most respected and sought-after performance engines ever produced.

Engine Variants

Evo I–III (1992–1995)

The early Mitsubishi Lancer Evolution I–III models introduced the 4G63T to Mitsubishi’s rally-focused lineup. These cars used a 7-bolt engine with a TD05 turbo and a relatively raw, lightweight setup built for homologation rally racing. They are known for being simple, aggressive, and highly responsive, laying the foundation for the Evolution legacy

Evo IV–VI (1996–2000)

The Mitsubishi Lancer Evolution IV–VI generation brought a major redesign, including a new chassis orientation with improved airflow and cooling efficiency. Power delivery became smoother and more controlled, while turbo response improved significantly. Evo VI further refined durability and cooling, making this era one of the most balanced and reliable versions of the 4G63T.

Evo VII–VIII (2001–2005)

The Mitsubishi Lancer Evolution VII–VIII models moved to a larger chassis and introduced advanced electronics like Active Center Differential (ACD). The engine remained the 4G63 but was tuned for better drivability and stability at higher speeds. Evo VIII also marked the model’s introduction to the U.S. market, increasing its global popularity.

Evo IX (2005–2007)

The Mitsubishi Lancer Evolution IX was the final and most refined 4G63T Evolution, featuring MIVEC variable valve timing on the intake cam. This improved mid-range torque, throttle response, and reduced turbo lag. It represents the peak evolution of the 4G63T before Mitsubishi transitioned to the 4B11T engine in later models.
