This article will delve into the key features of the 4G63T engine, its history, applications, common issues, and provide a section of frequently asked questions (FAQs) for enthusiasts and potential buyers.

Key Features of the Mitsubishi 4G63T 2.0L DOHC Turbo Engine

1. Engine Configuration

• Displacement: 2.0L (1997cc)
• Cylinders: Inline-4
• Valvetrain: DOHC (Double Overhead Camshafts)
• Turbocharged: Yes, with intercooling for improved performance

The engine uses an inline four-cylinder design that helps reduce weight and enhances fuel efficiency while still delivering substantial power. The DOHC configuration allows for precise valve control, which is vital for maximizing the engine’s performance at higher RPMs.

2. Turbocharging

The 4G63T’s turbocharger gives the engine a significant power boost compared to naturally aspirated versions. It improves the engine’s efficiency by forcing more air into the combustion chamber, allowing for more fuel to be burned and producing more power. This turbocharged setup is a major reason the engine is favored in performance applications.

3. Performance and Power Output

The standard output of the 4G63T varies depending on the vehicle and configuration, but typically it produces:

• Horsepower: Around 150 to 190 hp (varies by model)
• Torque: 190-200 lb-ft (varies by model)

Performance versions, like those found in the Mitsubishi Lancer Evolution I-III, were known to exceed 250 horsepower in some configurations, showcasing the engine’s tunability and its ability to handle significant power increases.

4. Applications

The 4G63T engine has been used in a variety of Mitsubishi and other performance-oriented vehicles. Some of the most notable applications include:

• Mitsubishi Lancer Evolution I-III: These models featured the 4G63T engine as the heart of their performance.
• Mitsubishi Eclipse GS Turbo: Used in the first and second generations of this popular sports car.
• Mitsubishi Galant VR-4: One of the first vehicles to feature this engine and the precursor to the Lancer Evolution series.
• Eagle Talon TSi: A collaboration between Mitsubishi and Chrysler, this vehicle also featured the 4G63T.

5. Reliability and Durability

The 4G63T is known for its durability, especially when maintained properly. It has been proven to handle high levels of horsepower and torque, making it a great option for tuners and racing enthusiasts. The block is often referred to as “bulletproof” when properly cared for, and many owners have achieved significant mileage with these engines.

Common Issues with the Mitsubishi 4G63T

Despite its reputation for reliability, the 4G63T engine is not without its potential problems. Some common issues include:

• Turbo Wear: Over time, the turbocharger can experience wear, leading to issues such as oil leaks, reduced boost, or even turbo failure. Regular maintenance, including oil changes, can help mitigate this issue.
• Head Gasket Failure: High compression and excessive heat can lead to head gasket failure. This can result in coolant leaks, overheating, and in extreme cases, engine failure.
• Timing Belt Failure: Like many Mitsubishi engines, the 4G63T uses a timing belt, which requires regular inspection and replacement. A snapped timing belt can cause significant internal engine damage.
• Oil Starvation: Poor maintenance or oil pump failure can lead to oil starvation, which can quickly damage internal components like the turbocharger and bearings.
