The Mazdaspeed 3 is a popular choice among car enthusiasts due to its turbocharged engine and sporty performance. One of the most significant upgrades that can be made to this vehicle is the turbocharger upgrade, which can enhance power output dramatically. This article will explore the process of upgrading the turbocharger from the stock 18 psi to 24 psi, resulting in an additional 80 horsepower.
Understanding Turbocharger Basics
A turbocharger is a device that uses exhaust gases to spin a turbine, which then compresses incoming air to increase the engine’s power. The stock Mazdaspeed 3 turbocharger operates at 18 psi, which is sufficient for a fun driving experience. However, for those seeking more power, increasing boost pressure to 24 psi can offer significant performance gains.
Benefits of Upgrading to 24 Psi
Upgrading the turbocharger to run at 24 psi provides several benefits:
- Increased Horsepower: An additional 80 hp can transform the driving experience.
- Improved Throttle Response: Higher boost pressure can lead to quicker acceleration.
- Enhanced Performance: Better overall performance in various driving conditions.
Key Components Needed for the Upgrade
To achieve the desired boost level, several components must be upgraded or replaced. Here are the key components needed for the upgrade:
- Upgraded Turbocharger: A larger turbocharger that can handle 24 psi.
- High-Flow Fuel Injectors: To provide adequate fuel supply at higher boost levels.
- Performance Intercooler: To keep intake temperatures low and maintain performance.
- Upgraded Exhaust System: To improve exhaust flow and reduce back pressure.
- Tuning Software: Essential for adjusting the engine’s fuel maps and boost levels.
Installation Process
The installation of a turbocharger upgrade requires mechanical knowledge and experience. Here’s a general overview of the installation process:
- Remove the Stock Turbocharger: Disconnect all necessary components and remove the old turbo.
- Install Upgraded Turbocharger: Position the new turbocharger and secure it in place.
- Upgrade Fuel Injectors: Replace stock injectors with high-flow versions.
- Install Performance Intercooler: Position the intercooler and connect piping.
- Upgrade Exhaust System: Install a new exhaust system to enhance flow.
- Connect Tuning Software: Load the appropriate tuning software to adjust the engine settings.
Tuning for Optimal Performance
After installation, tuning is crucial to ensure the engine runs efficiently and safely at the new boost levels. A professional tuner can help optimize the air-fuel ratio and ignition timing, which are vital for performance and reliability.
Potential Risks and Considerations
While upgrading the turbocharger can lead to impressive gains, it’s essential to consider potential risks:
- Engine Stress: Increased boost can put additional stress on engine components.
- Fuel Quality: Higher boost levels may require higher octane fuel to prevent knocking.
- Warranty Issues: Modifications may void manufacturer warranties.
Conclusion
Upgrading the turbocharger on a Mazdaspeed 3 from 18 psi to 24 psi can provide an exhilarating boost in performance, resulting in an additional 80 hp. However, it is crucial to approach this modification with careful planning, proper installation, and professional tuning to maximize the benefits while minimizing risks. With the right upgrades, the Mazdaspeed 3 can truly become a powerhouse on the road.
