Choosing the right turbocharger for your A45 can significantly impact performance and driving experience. Two popular options are the Garrett GTX 2863 and the BorgWarner EFR 7163. In this article, we will compare these two turbochargers to help you make an informed decision.
Understanding Turbochargers
Turbochargers are devices that increase the efficiency and power output of an engine by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in increased horsepower and torque.
Key Factors to Consider
- Engine compatibility
- Power goals
- Response time
- Installation complexity
- Budget
Garrett GTX 2863 Overview
The Garrett GTX 2863 is a popular choice among performance enthusiasts. It features a lightweight design and advanced aerodynamics, which contribute to its efficiency and response.
Specifications
- Compressor Wheel Size: 60mm
- Turbine Wheel Size: 53mm
- Max Power Output: Up to 500 HP
- Boost Pressure: 1.5 bar
Advantages
- Quick spool time
- High power potential
- Excellent build quality
Disadvantages
- Can be expensive
- May require custom installation
BorgWarner EFR 7163 Overview
The BorgWarner EFR 7163 is another strong contender in the turbocharger market, known for its innovative technology and performance capabilities.
Specifications
- Compressor Wheel Size: 62mm
- Turbine Wheel Size: 54mm
- Max Power Output: Up to 600 HP
- Boost Pressure: 2.0 bar

Performance Comparison
When comparing the performance of the Garrett GTX 2863 and the BorgWarner EFR 7163, several factors come into play, including power delivery, spool time, and overall efficiency.
Power Delivery
The BorgWarner EFR 7163 has a slight edge in maximum power output, making it suitable for those looking to push their A45 to higher performance levels. However, the Garrett GTX 2863 offers a more linear power delivery, which can be beneficial for daily driving.
Spool Time
The Garrett GTX 2863 is known for its quick spool time, allowing drivers to experience boost at lower RPMs. The BorgWarner EFR 7163, while still responsive, may take slightly longer to spool due to its larger compressor wheel.
Overall Efficiency
Both turbochargers are designed with efficiency in mind, but the Garrett GTX 2863 may provide better fuel economy at lower power levels, while the BorgWarner EFR 7163 excels at high boost scenarios.
Installation Considerations
Installing a turbocharger can be a complex process that requires specific knowledge and tools. Here are some considerations for both options:
- Compatibility with existing engine components
- Required modifications for fitment
- Potential need for tuning after installation
Budget and Value
Both the Garrett GTX 2863 and the BorgWarner EFR 7163 come with a premium price tag. It’s essential to consider your budget and the value each turbocharger brings to your performance goals.
Conclusion
Choosing between the Garrett GTX 2863 and the BorgWarner EFR 7163 ultimately depends on your performance goals, driving style, and budget. Both turbochargers offer unique advantages that cater to different needs. Assess your priorities and make an informed decision to enhance your A45’s performance.
