The quest for more power in K-series engines has led many enthusiasts to explore turbocharging options. Among the popular choices are the Garrett GTX2860R and the BorgWarner EFR 9174 turbos. Both of these kits promise to boost power significantly, often exceeding 400 horsepower. In this article, we’ll compare these two turbo options to help you decide which one is the best fit for your performance goals.
Overview of Turbochargers
Turbochargers are essential in enhancing the performance of an engine by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in increased power output. Let’s take a closer look at the two contenders in this comparison.
Garrett GTX2860R
The Garrett GTX2860R is a popular choice among K-series engine builders. Known for its efficiency and reliability, this turbocharger offers a good balance of power and response.
Specifications
- Compressor Wheel Diameter: 60mm
- Turbine Wheel Diameter: 53mm
- Maximum Horsepower: 400+ HP
- Boost Threshold: 3000 RPM
The GTX2860R is designed for quick spool times, making it an excellent choice for street applications as well as track use. Its compact size allows for easy installation in various K-series setups.
BorgWarner EFR 9174
The BorgWarner EFR 9174 is another strong contender, known for its advanced technology and performance capabilities. This turbocharger is designed for enthusiasts looking for maximum power and efficiency.
Specifications
- Compressor Wheel Diameter: 67mm
- Turbine Wheel Diameter: 56mm
- Maximum Horsepower: 450+ HP
- Boost Threshold: 3500 RPM
The EFR 9174 features a larger compressor wheel, which contributes to its higher power potential. It also incorporates advanced features such as a built-in boost control and a lightweight design for improved responsiveness.
Performance Comparison
When it comes to performance, both turbochargers have their strengths. The choice between the Garrett GTX2860R and the BorgWarner EFR 9174 ultimately depends on your specific goals and preferences.
Power Output
Both turbos can achieve power outputs exceeding 400 HP, but the EFR 9174 has a slight edge due to its larger compressor wheel. This can lead to higher peak power numbers, especially in high-rev applications.
Spool Time
The Garrett GTX2860R is known for its quick spool time, making it ideal for street use where responsiveness is crucial. The EFR 9174, while still responsive, may take slightly longer to spool due to its larger size.
Installation and Compatibility
Both turbochargers can be installed on K-series engines, but the Garrett GTX2860R is often considered easier to fit due to its compact design. The EFR 9174 may require more modifications depending on the specific application.
Cost Considerations
Pricing can vary significantly between the two turbochargers. Typically, the Garrett GTX2860R is more budget-friendly, making it a popular choice for those looking for a cost-effective solution to boost power. The BorgWarner EFR 9174, while more expensive, offers advanced features that may justify the higher price for some enthusiasts.
Conclusion
In summary, both the Garrett GTX2860R and the BorgWarner EFR 9174 are excellent choices for boosting power in K-series engines. The GTX2860R excels in responsiveness and ease of installation, while the EFR 9174 offers greater peak power potential and advanced features. Your choice should ultimately depend on your performance goals, budget, and specific vehicle setup.
Whichever turbocharger you choose, both options will provide significant performance gains and enhance your driving experience. Happy boosting!
