The 4G63 engine, known for its robust design and tuning potential, is a favorite among performance enthusiasts. When it comes to maximizing power while keeping stock internals, selecting the right turbocharger is crucial. This article will guide you through the best options for turbo selection that can help you achieve impressive power gains without compromising reliability.
Understanding the 4G63 Engine
The 4G63 engine is a 2.0L inline-4 engine produced by Mitsubishi. It has gained a reputation for its turbocharged variants, particularly in the Mitsubishi Eclipse and Lancer Evolution models. The engine’s strength lies in its forged internals, which can handle significant power when properly tuned.
Key Considerations for Turbo Selection
- Power Goals: Determine your target horsepower and torque.
- Turbo Size: Choose a turbo that matches your power goals without exceeding the limits of stock internals.
- Boost Levels: Understand the safe boost levels for stock components.
- Response and Lag: Consider how quickly you want the turbo to spool.
- Fuel Management: Ensure your fuel system can support the increased demand.
Power Goals
Before selecting a turbo, it’s essential to define your power goals. For a 4G63 with stock internals, a realistic target is between 350 to 400 horsepower. Exceeding this range can risk engine failure, so it’s vital to stay within safe limits.
Turbo Size
Turbo size significantly impacts performance. A turbo that is too large may lead to increased lag, while one that is too small may not provide the desired power. For the 4G63, consider a turbo in the range of 16G to 20G for optimal performance with stock internals.
Boost Levels
Boost levels are another critical factor. Stock internals can typically handle up to 20 psi of boost safely. Going beyond this can lead to detonation and engine damage. It’s essential to tune your engine properly to ensure it runs smoothly at your desired boost level.
Response and Lag
Turbo response is crucial for driving enjoyment. Smaller turbos tend to spool faster, providing power at lower RPMs, while larger turbos may take longer to reach full boost. For a balanced approach, a turbo like the 16G provides a good compromise between response and power.
Fuel Management
Increased power demands more fuel. Upgrading the fuel injectors and ensuring your fuel pump can handle the increased flow is vital. A proper fuel management system will help maintain the correct air-fuel ratio, preventing lean conditions that can damage the engine.
Recommended Turbochargers for 4G63
