The 4G63 engine has earned a reputation for its reliability and performance potential, especially when it comes to turbo builds. With the right components and tuning, achieving 600 horsepower is a realistic goal for enthusiasts. This article will explore the best piping, intercoolers, and clutch options to support a reliable 4G63 turbo build.
Understanding the 4G63 Engine
The 4G63 is a 2.0-liter inline-four engine that was used in various Mitsubishi models, including the Eclipse and Lancer Evolution. Known for its robust design and tunable nature, the 4G63 can handle significant power increases when modified correctly. Before diving into the specifics of turbo builds, it’s essential to understand its components and capabilities.
Best Piping Options for 4G63 Turbo Builds
Piping plays a crucial role in the performance of a turbocharged engine. It affects airflow, turbo response, and overall efficiency. Here are some recommended piping options for a reliable 4G63 turbo build:
- Turbo Inlet Piping: Upgrading to larger diameter piping can reduce restrictions and improve turbo spool time.
- Intercooler Piping: Use mandrel-bent aluminum or stainless steel piping for smooth airflow and reduced pressure drops.
- Blow-Off Valve (BOV) Piping: Ensure proper placement of the BOV to prevent compressor surge and maintain boost pressure.
- Exhaust Piping: A 3-inch or larger exhaust system will help reduce backpressure and improve overall engine efficiency.
Turbo Inlet Piping
For optimal performance, consider using a 3-inch inlet pipe. This larger diameter allows for more air to flow into the turbo, reducing spool time and improving throttle response. Brands like Mishimoto and ETS offer high-quality options that fit well with the 4G63 setup.
Intercooler Piping
Intercooler piping should be as short and direct as possible to minimize pressure loss. Using high-flow couplers and clamps will ensure a secure fit and prevent leaks. Look for options that come with a complete kit for easy installation.
Choosing the Right Intercooler
An efficient intercooler is vital for maintaining optimal intake temperatures, which can significantly affect performance. Here are some top choices for the 4G63 turbo build:
- Front Mount Intercoolers (FMIC): These provide better airflow and cooling efficiency compared to stock options.
- Core Size: Aim for a core size of at least 24x12x3 inches to handle the heat generated at higher boost levels.
- Material: Look for aluminum intercoolers, as they are lightweight and offer excellent thermal conductivity.
- Brand Recommendations: Brands like Mishimoto, ETS, and Precision offer reliable intercoolers suitable for high horsepower builds.
Front Mount Intercoolers
Front mount intercoolers are preferred for high-performance builds due to their ability to cool air more effectively. Ensure proper mounting to avoid airflow obstruction. Consider the piping layout to facilitate smooth airflow from the turbo to the intercooler and then to the intake manifold.
Clutch Options for 600 HP Builds
With increased power comes the need for a reliable clutch system. A stock clutch will likely fail under high horsepower conditions. Here are some clutch options that can handle 600 hp:
- Clutch Type: Consider a twin-disc clutch for better torque handling and smoother engagement.
- Material: Organic and ceramic materials offer different benefits; organic is smoother while ceramic can handle more power.
- Brand Recommendations: Brands like ACT, Exedy, and Clutch Masters provide high-performance clutches designed for turbo applications.
Twin-Disc Clutch Systems
Twin-disc clutches are ideal for high horsepower builds, as they distribute the load more evenly and offer better heat dissipation. This type of clutch can handle the stress of launching and high RPMs without slipping, making it a reliable choice for a 600 hp 4G63 setup.
Final Thoughts on Building a Reliable 4G63 Turbo Setup
Building a reliable 4G63 turbo setup capable of producing 600 horsepower requires careful selection of components. From piping to intercoolers and clutches, each part plays a significant role in ensuring performance and reliability. By investing in quality parts and proper tuning, you can achieve impressive power while maintaining the integrity of your engine.
Additional Tips for 4G63 Turbo Builds
Here are some additional tips to keep in mind when building your 4G63 turbo engine:
- Regular Maintenance: Keep up with regular oil changes and inspect your turbo for any signs of wear.
- Tuning: Proper tuning is crucial. Consider working with a professional tuner who understands the 4G63 platform.
- Fuel System: Upgrade your fuel injectors and pump to support higher horsepower levels.
- Engine Management: Use a reliable engine management system to optimize performance and ensure safety.
