Stock Turbocharger Specifications
The stock turbocharger on the Mazdaspeed 3 is designed to provide reliable performance at 263 hp. However, it has limitations in terms of airflow and boost pressure. Upgrading to a larger turbo can significantly increase power output.
Choosing the Right Turbo Upgrade
When selecting a turbo upgrade, it’s essential to consider various factors such as size, efficiency, and compatibility with the existing engine components. Here are some popular turbo options for the Mazdaspeed 3:
- Garrett GT2871R
- FP Black Turbo
- ATP GTX2867R
Garrett GT2871R
The Garrett GT2871R is a popular choice among Mazdaspeed 3 enthusiasts. It offers a good balance of spool time and top-end power, making it suitable for both street and track use.
FP Black Turbo
The FP Black Turbo is known for its high power potential and efficiency. It can support power levels well above 330 hp, making it a great option for those looking to push their Mazdaspeed 3 to the limits.
ATP GTX2867R
The ATP GTX2867R is another excellent turbo upgrade that provides quick spool times and a significant increase in horsepower. This turbo is ideal for those seeking a balance between daily drivability and track performance.
Supporting Modifications for Increased Power
Upgrading the turbo alone is not enough to achieve a power increase from 263 hp to 330 hp. Supporting modifications are necessary to ensure the engine can handle the additional power. Consider the following upgrades:
- Upgraded intercooler
- High-flow fuel injectors
- Performance exhaust system
- ECU tuning
Upgraded Intercooler
An upgraded intercooler is essential for reducing intake air temperatures, which helps maintain performance and engine reliability. A larger, more efficient intercooler can significantly improve power output.
High-Flow Fuel Injectors
To support increased power levels, high-flow fuel injectors are necessary. These injectors ensure that the engine receives enough fuel to match the increased airflow from the upgraded turbo.
Performance Exhaust System
A performance exhaust system helps reduce back pressure and improves exhaust flow. This upgrade can enhance turbo spool time and overall engine performance.
ECU Tuning
After all hardware upgrades, proper ECU tuning is crucial. A professional tune will optimize fuel maps, ignition timing, and boost levels to ensure the engine runs smoothly and efficiently at the new power levels.
Installation Process
The installation of a turbo upgrade and supporting modifications requires mechanical knowledge and experience. Here’s a general overview of the process:
- Remove the stock turbo and exhaust components
- Install the upgraded turbo and intercooler
- Replace fuel injectors
- Install the performance exhaust system
- Reflash the ECU with a custom tune
Conclusion
Upgrading the turbo on a Mazdaspeed 3 can lead to impressive gains in horsepower, transforming the driving experience. With careful selection of components and proper installation, reaching 330 hp is an attainable goal. Always remember to consider supporting modifications and professional tuning to ensure reliability and performance.
