The 4G63 engine is renowned in the automotive community for its performance potential, especially when modified. In this article, we will explore the differences between stock performance and upgraded performance, specifically aiming for 400 horsepower using the FP3 turbo and HKS exhaust system. This guide is designed for enthusiasts looking to enhance their vehicle’s performance.
Understanding the 4G63 Engine
The 4G63 is a turbocharged inline-4 engine that has been used in various Mitsubishi models, including the Eclipse and Lancer Evolution. Known for its robust design, it has a strong aftermarket support that allows for significant performance upgrades.
Stock Performance of the 4G63
In its stock form, the 4G63 engine produces approximately 190 to 200 horsepower, depending on the specific model and year. This performance is adequate for daily driving but leaves much to be desired for performance enthusiasts.
Key Specifications of Stock 4G63
- Engine Type: Inline-4, Turbocharged
- Displacement: 2.0L
- Power Output: 190-200 HP
- Torque: Approximately 205 lb-ft
Upgrading to 400 HP
To achieve 400 horsepower, several modifications are necessary. The FP3 turbo and HKS exhaust are key components in this performance upgrade. Let’s delve into how each of these components contributes to the overall power increase.
FP3 Turbocharger
The FP3 turbo is designed to significantly increase airflow into the engine, allowing for greater fuel combustion and power output. This turbo can handle higher boost levels, which is essential for reaching the 400 HP goal.
HKS Exhaust System
The HKS exhaust system complements the FP3 turbo by improving exhaust flow. A less restrictive exhaust allows for quicker turbo spool and improved overall engine efficiency. This combination is crucial for achieving the desired horsepower.
Additional Modifications for Optimal Performance
While the FP3 turbo and HKS exhaust are critical, additional modifications will help maximize performance. Here are some recommended upgrades:
- Upgraded Fuel Injectors: To supply the necessary fuel for higher power levels.
- Aftermarket Fuel Pump: Ensures adequate fuel delivery under high boost conditions.
- ECU Tune: A custom tune is essential to optimize the engine’s performance with the new components.
- Intercooler Upgrade: Helps to reduce intake temperatures, improving efficiency and power.
- High-Performance Intake System: Increases airflow to the engine for better combustion.
Performance Expectations
With the combination of the FP3 turbo, HKS exhaust, and additional modifications, reaching 400 horsepower is achievable. However, it’s important to note that actual results can vary based on tuning, engine condition, and installation quality.
Real-World Performance Metrics
Owners who have completed this upgrade often report impressive performance metrics, including:
- 0-60 mph in under 5 seconds
- Quarter-mile times in the low 12-second range
- Increased throttle response and overall drivability
Conclusion
Upgrading the 4G63 engine to achieve 400 horsepower is an exciting journey for any car enthusiast. With the right components, including the FP3 turbo and HKS exhaust, along with supporting modifications, you can transform your vehicle into a powerful machine. Always remember to invest in quality parts and professional tuning to ensure the best performance and reliability.
