The turbocharger is a critical component for enhancing the performance of the 2JZ-GTE engine, a legendary powerplant found in the Toyota Supra. When seeking to achieve over 600 horsepower, two popular choices emerge: the Garrett GT3582 and the Precision 6266. This article will compare these two turbochargers, their specifications, and their performance characteristics to help you make an informed decision.
Overview of the 2JZ-GTE Engine
The 2JZ-GTE engine is a 3.0-liter inline-six engine known for its robust design and tuning potential. With a cast-iron block and aluminum DOHC cylinder head, it has become a favorite among tuners and enthusiasts alike. The engine is capable of handling significant power increases with the right modifications.
Garrett GT3582 Turbocharger
The Garrett GT3582 is a popular choice for those looking to push the limits of their 2JZ-GTE. This turbocharger is known for its efficiency and ability to support high horsepower levels while maintaining a responsive powerband.
Specifications
- Compressor Wheel Diameter: 61mm
- Turbine Wheel Diameter: 76mm
- Max Horsepower: 600 HP
- Compressor A/R: 0.60 / 0.82
- Turbine A/R: 0.63 / 0.82
Performance Characteristics
The GT3582 offers a balance of power and responsiveness. It is capable of producing significant boost pressure while maintaining quick spool times. This characteristic makes it suitable for both street and track applications.
Precision 6266 Turbocharger
The Precision 6266 turbocharger is another excellent option for those looking to achieve over 600 horsepower with their 2JZ-GTE. Known for its high flow capabilities, the 6266 is designed for serious performance applications.
Specifications
- Compressor Wheel Diameter: 66mm
- Turbine Wheel Diameter: 76mm
- Max Horsepower: 700 HP
- Compressor A/R: 0.70
- Turbine A/R: 0.84
Performance Characteristics
The Precision 6266 is known for its ability to produce high horsepower numbers while maintaining a strong powerband. It features a larger compressor wheel, which allows for increased airflow and boost pressure, making it ideal for high-performance builds.
Comparison of Garrett GT3582 and Precision 6266
When choosing between the Garrett GT3582 and the Precision 6266, there are several factors to consider. Both turbochargers are capable of supporting over 600 horsepower, but their performance characteristics differ.
Power Output
The Precision 6266 has a higher maximum horsepower rating, making it a better choice for those looking to push beyond 600 HP. The Garrett GT3582, while slightly lower in maximum output, offers excellent responsiveness and a more linear power delivery.
Response Time
The Garrett GT3582 is known for its quick spool time, making it a great option for street applications where responsiveness is key. The Precision 6266, while still responsive, may take slightly longer to spool due to its larger compressor wheel.
Installation and Compatibility
Both turbochargers can be installed on the 2JZ-GTE with the right supporting modifications. However, the specific fitment may vary based on the vehicle setup and additional components used in the build.
Conclusion
In conclusion, both the Garrett GT3582 and Precision 6266 turbochargers are excellent choices for those looking to achieve over 600 horsepower with their 2JZ-GTE engines. The decision ultimately comes down to individual preferences regarding power delivery, responsiveness, and specific performance goals.
Whether you choose the Garrett GT3582 for its quick spool and street-friendly characteristics or the Precision 6266 for its high-flow capabilities, both options will significantly enhance the performance of your 2JZ-GTE engine.
