The Mitsubishi Eclipse equipped with the 4G63 engine is a beloved platform among car enthusiasts, especially those interested in performance tuning. One of the most significant upgrades for this engine is the installation of a turbocharger. In this article, we will compare two popular turbochargers for 4G63 builds: the Garrett GT3076R and the Tial 6066. Both of these turbochargers have their unique features and benefits, making them suitable for different types of builds and driving styles.
Overview of the 4G63 Engine
The 4G63 engine is a 2.0-liter inline-four engine that has gained a reputation for its robustness and tuning potential. Found in various Mitsubishi models, especially the Eclipse, this engine can handle significant power increases with the right modifications. Turbocharging the 4G63 can lead to impressive horsepower gains, making it a popular choice for racers and street enthusiasts alike.
Garrett GT3076R Turbocharger
The Garrett GT3076R is a well-known turbocharger that has been a favorite among performance tuners for years. It offers a great balance of power and efficiency, making it an excellent choice for a range of builds.
Specifications
- Compressor Wheel: 76mm
- Turbine Wheel: 64mm
- Compressor Housing: A/R 0.60 or 0.82
- Turbine Housing: A/R 0.63 or 0.82
Performance Characteristics
The GT3076R is capable of producing power levels of up to 500 horsepower, depending on the supporting modifications. It spools relatively quickly, providing a good balance between low-end torque and high-end horsepower. This makes it suitable for both daily driving and track use.
Installation and Compatibility
Installing the GT3076R on a 4G63 engine typically requires a custom manifold and downpipe. However, many aftermarket companies offer bolt-on kits to simplify the installation process. It is essential to ensure that the supporting modifications, such as fuel injectors and engine management, are also upgraded to handle the increased power.
Tial 6066 Turbocharger
The Tial 6066 is another popular choice among tuners looking to extract maximum performance from their 4G63 engines. Known for its durability and efficiency, the Tial 6066 is designed for high-performance applications.
Specifications
- Compressor Wheel: 66mm
- Turbine Wheel: 62mm
- Compressor Housing: A/R 0.82
- Turbine Housing: A/R 0.83
Performance Characteristics
The Tial 6066 can support power levels exceeding 600 horsepower, making it an excellent option for those aiming for extreme performance. It has a slightly larger compressor wheel than the GT3076R, which allows for more airflow and higher power potential. However, this can also result in a slower spool time compared to the Garrett turbo.
Installation and Compatibility
Like the GT3076R, the Tial 6066 requires custom installation. It is crucial to pair it with the right supporting modifications, including a robust fuel system and upgraded engine management. The installation process may be more involved due to its larger size, so careful planning is necessary.
Comparative Analysis
When choosing between the Garrett GT3076R and the Tial 6066, several factors should be considered:
- Power Goals: If your goal is to reach around 500 horsepower, the GT3076R is a great choice. For those aiming for 600+ horsepower, the Tial 6066 is more suitable.
- Spool Time: The GT3076R generally spools faster, making it better for street applications where quick throttle response is desired.
- Installation Complexity: Both turbos require custom installations, but the Tial 6066 may need more modifications due to its size.
- Cost: Pricing can vary, but typically, the Tial 6066 is more expensive than the GT3076R.
Conclusion
Both the Garrett GT3076R and the Tial 6066 are excellent turbocharger options for the 4G63 Eclipse builds. Your choice will ultimately depend on your specific performance goals, budget, and installation capabilities. Whether you opt for the efficiency of the GT3076R or the raw power potential of the Tial 6066, both will significantly enhance your driving experience.
