The 6G72 engine, known for its robust performance, is a popular choice among automotive enthusiasts looking to enhance their vehicle’s power output. One effective way to achieve significant performance gains is through the use of twin turbos. In this article, we will explore the best size for 6G72 twin turbo modifications, focusing on the advantages of choosing 60mm turbos to achieve a target of 500-550 horsepower.
Understanding the 6G72 Engine
The 6G72 is a 3.0-liter V6 engine produced by Mitsubishi. It has a strong aftermarket support and is commonly found in vehicles like the Mitsubishi 3000GT and Dodge Stealth. Its design allows for substantial upgrades, particularly in forced induction applications. The twin turbo setup enhances its power delivery and efficiency, making it a prime candidate for performance modifications.
Why Choose 60mm Turbos?
When selecting turbos for the 6G72, size plays a crucial role in achieving the desired horsepower. The choice of 60mm turbos is optimal for several reasons:
- Boost Response: 60mm turbos provide a quicker spool time, resulting in improved throttle response.
- Power Band: They effectively support the 500-550 hp range without excessive lag.
- Efficiency: These turbos maintain a good balance between power output and fuel efficiency.
Factors to Consider When Choosing Turbos
When selecting turbos for your 6G72 setup, consider the following factors:
- Engine Goals: Define your performance goals. Are you aiming for street use, track, or both?
- Supporting Mods: Ensure your engine has the necessary supporting modifications, such as upgraded fuel injectors, intercoolers, and exhaust systems.
- Tuning: Proper tuning is essential to maximize the potential of the turbos and prevent engine damage.
Recommended Supporting Modifications
To achieve optimal performance with 60mm turbos, consider the following supporting modifications:
- Fuel System Upgrades: Upgrading to larger fuel injectors and a high-flow fuel pump will ensure adequate fuel delivery.
- Intercooler: A larger intercooler will improve air intake temperatures, enhancing performance and reliability.
- Exhaust System: A high-flow exhaust system will reduce back pressure and improve turbo efficiency.
- Tuning Software: Utilize a reputable tuning software to adjust fuel maps and ignition timing for optimal performance.
Installation Tips
Installing 60mm turbos on a 6G72 engine requires careful planning and execution. Here are some tips to ensure a successful installation:
- Follow Manufacturer Instructions: Always refer to the turbo manufacturer’s installation guide for specific instructions.
- Use Quality Parts: Invest in high-quality gaskets, fittings, and hoses to prevent leaks and ensure longevity.
- Check for Clearances: Ensure that the turbos fit properly and do not interfere with other components in the engine bay.
- Professional Help: If unsure, consider hiring a professional to assist with the installation to avoid costly mistakes.
Tuning for Optimal Performance
Once the turbos are installed, tuning is crucial for achieving the desired performance. A proper tune will maximize horsepower while ensuring engine safety. Here are some tuning considerations:
- Dyno Tuning: A dyno session will provide accurate data on power output and allow for precise adjustments.
- Monitor Air-Fuel Ratios: Keeping an eye on air-fuel ratios ensures the engine runs efficiently and safely.
- Adjust Timing: Optimize ignition timing to enhance power and prevent knock.
Conclusion
Choosing 60mm turbos for your 6G72 engine can significantly enhance performance, allowing you to achieve a target of 500-550 horsepower. By considering supporting modifications, ensuring proper installation, and executing a thorough tuning process, you can unlock the full potential of your engine. With the right setup, your 6G72 will deliver exhilarating performance on the street or the track.
