Performance Comparison
When comparing the Precision 5857 and the Garrett GTX2867R, there are several performance metrics to consider. These include spool time, peak horsepower, and overall drivability.
Spool Time
Spool time is critical for turbocharged vehicles, as it determines how quickly the turbo can deliver boost. The Precision 5857 is known for its quick spool characteristics, often reaching full boost at lower RPMs compared to the GTX2867R.
Peak Horsepower
Both turbos can achieve impressive peak horsepower. However, the Garrett GTX2867R has a slight edge in terms of maximum power output, capable of reaching up to 600 HP, compared to the Precision 5857’s 550 HP limit.
Drivability
Drivability is an essential factor for daily drivers. The Precision 5857 offers a more linear power delivery, making it easier to control in various driving conditions. In contrast, the GTX2867R, while powerful, may feel more aggressive and harder to manage for some drivers.
Response and Efficiency
Response and efficiency are crucial for any turbocharger. A turbo that responds quickly and efficiently can enhance the overall driving experience.
Response
The Precision 5857 is designed for quick response, allowing for rapid acceleration and improved throttle response. The Garrett GTX2867R, while still responsive, may take slightly longer to spool due to its larger size.
Efficiency
In terms of efficiency, both turbos are well-engineered to maximize airflow and minimize lag. The Precision 5857 is often favored for its efficiency at lower boost levels, while the GTX2867R excels at higher boost levels.
Installation Considerations
Installing a new turbocharger requires careful consideration of various factors, including compatibility, tuning, and supporting modifications. Both the Precision 5857 and Garrett GTX2867R can be installed on a WRX, but there are differences in installation complexity.
- Precision 5857: Generally easier to install with fewer supporting modifications needed.
- Garrett GTX2867R: May require additional modifications and tuning for optimal performance.
Conclusion
In conclusion, both the Precision 5857 and Garrett GTX2867R turbos offer unique advantages for WRX enthusiasts. The Precision 5857 is ideal for those seeking quick response and ease of installation, while the Garrett GTX2867R is suited for those looking for maximum power and performance. Ultimately, the choice between these two turbos will depend on individual preferences and performance goals.
