The 4G63 engine has long been a favorite among automotive enthusiasts, particularly those looking to achieve high horsepower levels. With the right modifications, it is possible to push this engine to an impressive 800 horsepower. In this article, we will explore the ultimate 4G63 build, focusing on the essential components such as the PTE turbo and forged internals.
Understanding the 4G63 Engine
The 4G63 is a turbocharged inline-four engine that was originally developed by Mitsubishi. It has gained a reputation for its robustness and adaptability, making it a popular choice for tuning and performance builds.
Key features of the 4G63 include:
- 2.0-liter displacement
- DOHC design
- Turbocharged from the factory
- Strong aftermarket support
Essential Components for an 800 HP Build
To achieve 800 horsepower from a 4G63 engine, several critical components must be upgraded. Here are the primary parts you need to focus on:
- PTE Turbo
- Forged Internals
- Upgraded Fuel System
- High-Performance Engine Management
- Intercooler Upgrade
PTE Turbo Selection
The choice of turbocharger is crucial for achieving the desired horsepower. PTE (Precision Turbo & Engine) offers a range of turbos that can support high horsepower builds. For an 800 HP goal, consider the following options:
- PTE 6266
- PTE 6766
- PTE 6870
Each of these turbos provides a balance of power and response, making them ideal for high-performance applications.
Forged Internals
Stock internals will not withstand the stress of 800 HP. Upgrading to forged internals is essential. Key components include:
- Forged Pistons
- Forged Connecting Rods
- Upgraded Crankshaft
These components provide the strength and durability needed for high boost levels and extreme power output.
Supporting Modifications
In addition to the core components, several supporting modifications are necessary to ensure reliability and performance. These include:
- Upgraded Fuel System
- High-Flow Fuel Injectors
- Aftermarket Fuel Pump
- Enhanced Cooling System
- ECU Tuning
Upgraded Fuel System
A high-performance fuel system is vital for delivering the necessary fuel to support 800 HP. This includes:
- High-flow fuel injectors (1000cc or larger)
- Aftermarket fuel pump capable of supporting high horsepower
- Upgraded fuel lines and rails
Engine Management
Proper engine management is critical for optimizing performance and ensuring the engine runs smoothly. Consider using:
- Standalone ECU
- Tuning software for precise adjustments
- Wideband O2 sensor for monitoring air-fuel ratios
Building the Engine
With all the components gathered, it’s time to start the build process. Follow these steps to ensure a successful assembly:
- Disassemble the engine carefully, taking note of all parts.
- Install the forged internals, ensuring proper clearances.
- Attach the selected PTE turbo and associated piping.
- Upgrade the fuel system components as planned.
- Install the aftermarket ECU and set up the tuning software.
Tuning for Maximum Performance
Once the engine is assembled, the next step is tuning. Proper tuning is essential for achieving the desired horsepower and ensuring reliability. Work with a professional tuner who has experience with high horsepower 4G63 builds.
Key tuning aspects include:
- Adjusting fuel maps for optimal air-fuel ratios
- Tuning ignition timing for maximum efficiency
- Monitoring boost levels to prevent detonation
Conclusion
Achieving 800 horsepower from a 4G63 engine is a challenging but rewarding endeavor. By selecting the right components, such as a PTE turbo and forged internals, and ensuring proper tuning, enthusiasts can unlock the full potential of this legendary engine.
With dedication and the right knowledge, your 4G63 build can become a powerhouse on the road or track.
