The 4G63 engine has long been a favorite among automotive enthusiasts, particularly for those looking to build a cost-effective turbocharged setup. With the right components and tuning, achieving 400 horsepower is not only possible but can be done without breaking the bank. In this article, we will explore how to build a 4G63 turbo setup using an EFR turbo and supporting upgrades.
Understanding the 4G63 Engine
The 4G63 is a 2.0-liter inline-four engine that has gained a reputation for its durability and performance potential. Found in various Mitsubishi models, including the Eclipse and Talon, this engine is known for its robust construction and tuning capabilities. Its turbocharged variant can produce impressive power figures with the right modifications.
Choosing the Right Turbo: EFR Series
When it comes to selecting a turbocharger, the EFR (Engineered for Racing) series from BorgWarner stands out. These turbos are designed for efficiency and performance, making them ideal for a 4G63 build aiming for 400 hp. The EFR turbo offers quick spool times and a wide powerband, allowing for a responsive driving experience.
Benefits of EFR Turbochargers
Some of the key benefits of using an EFR turbo include:
- Lightweight Design: The use of advanced materials reduces weight.
- Integrated Wastegate: Simplifies installation and tuning.
- High Efficiency: Provides better power output with less lag.
- Durability: Built to withstand high temperatures and pressures.
Supporting Upgrades for 400 HP
To achieve 400 hp with your 4G63 turbo build, several supporting upgrades are necessary. These components will ensure your engine can handle the increased power and maintain reliability.
Essential Upgrades
- Fuel System: Upgrade to larger fuel injectors and a high-flow fuel pump to ensure proper fuel delivery.
- Engine Management: A standalone engine management system or a quality ECU tune is crucial for optimizing performance.
- Intercooler: An upgraded intercooler will help keep intake temperatures down, improving performance and reliability.
- Exhaust System: A high-flow exhaust system will reduce back pressure and improve turbo efficiency.
- Intake Manifold: Consider upgrading to a performance intake manifold for better airflow.
Building the Engine
Once you have selected your turbo and gathered the necessary supporting upgrades, it’s time to focus on the engine build itself. The 4G63 can handle significant power, but proper preparation is essential.
Internal Upgrades
To ensure your engine can handle the increased power, consider the following internal upgrades:
- Pistons: Upgrade to forged pistons for increased strength and reliability.
- Rods: Consider forged connecting rods to handle the stress of higher power levels.
- Head Gasket: A thicker or multi-layered head gasket will help prevent blowouts under high boost.
- Valve Springs: Upgraded valve springs will ensure proper seating and performance at high RPMs.
Tuning for Performance
After completing the build, tuning is crucial for achieving the desired power output and ensuring reliability. A professional tune will optimize fuel maps, ignition timing, and boost levels.
Choosing a Tuner
Selecting an experienced tuner familiar with the 4G63 platform is essential. Look for tuners who have a proven track record with similar builds and can provide data logging services to monitor performance.
Conclusion
Building a cost-effective 4G63 turbo setup capable of achieving 400 hp is an attainable goal with the right parts and knowledge. By choosing an EFR turbo and investing in supporting upgrades, you can create a powerful and reliable performance vehicle that will provide an exhilarating driving experience.
