The 4G63 engine, known for its performance in the Mitsubishi Eclipse, is a popular choice among car enthusiasts looking to enhance their vehicle’s power. One of the most significant upgrades for this engine is the turbocharger. In this article, we will compare two popular turbocharger options: the Garrett GT3076 and the BorgWarner EFR Series.
Understanding Turbochargers
Turbochargers are devices that increase the engine’s efficiency and power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in greater horsepower and torque. Choosing the right turbocharger is crucial for achieving the desired performance level.
Garrett GT3076 Turbocharger
The Garrett GT3076 is a popular choice for those looking to boost the performance of their 4G63 engine. Known for its reliability and efficiency, this turbocharger offers several features that make it an attractive option.
Specifications of the Garrett GT3076
- Compressor Wheel Diameter: 76 mm
- Turbine Wheel Diameter: 64 mm
- Compressor A/R: 0.60 or 0.70
- Turbine A/R: 0.82
Performance Characteristics
The Garrett GT3076 turbocharger is known for its ability to provide a broad power band, making it suitable for both street and track applications. It is capable of supporting power levels from 400 to 600 horsepower, depending on the setup and tuning.
