by

The Mazda Protege5 is a compact car that has gained a loyal following due to its practicality, affordability, and fun-to-drive nature. With a starting price around $2,000 for older models, many enthusiasts have turned their attention to this vehicle, seeking ways to enhance its performance. In this article, we will explore how simple modifications can help the Mazda Protege5 reach 130 horsepower, making it a more spirited ride without breaking the bank.

Understanding the Mazda Protege5

The Mazda Protege5, produced from 2001 to 2003, is a versatile hatchback that combines practicality with a sporty edge. It features a 2.0-liter inline-four engine, which, in stock form, produces around 130 horsepower. While this may seem modest, the car’s lightweight design allows for an engaging driving experience. With some simple modifications, you can unlock the potential of this vehicle.

Performance Modifications for Increased Horsepower

To achieve the goal of reaching 130 horsepower, several modifications can be implemented. These upgrades focus on improving airflow, enhancing engine efficiency, and optimizing the exhaust system. Below are some effective modifications you can consider:

  • Cold Air Intake: Replacing the factory air intake with a cold air intake system can significantly improve airflow to the engine, resulting in better combustion and increased horsepower.
  • High-Performance Exhaust System: Upgrading to a less restrictive exhaust system allows for better exhaust flow, which can enhance engine performance and provide a more aggressive sound.
  • ECU Tune: A performance tune can optimize fuel maps and ignition timing, extracting more power from the engine without any hardware changes.
  • Header Upgrade: Installing a performance header can improve exhaust flow and reduce back pressure, contributing to increased horsepower.
  • Lightweight Flywheel: A lightweight flywheel can improve throttle response and acceleration, making the car feel quicker and more agile.

Step-by-Step Modification Guide

Now that we have outlined the key modifications, let’s dive into a step-by-step guide on how to implement these changes effectively.

1. Installing a Cold Air Intake

Start by purchasing a cold air intake kit specifically designed for the Mazda Protege5. Follow these steps:

  • Gather necessary tools: socket set, screwdrivers, and pliers.
  • Remove the factory air intake system by disconnecting the airbox and intake tubing.
  • Install the new cold air intake according to the manufacturer’s instructions, ensuring all connections are secure.
  • Reconnect the battery and start the engine to check for any leaks or issues.

2. Upgrading the Exhaust System

Next, focus on the exhaust system. A high-performance cat-back exhaust system is recommended. Here’s how to install it:

  • Lift the car using jack stands for safety.
  • Remove the old exhaust system by unbolting it from the catalytic converter and hangers.
  • Install the new exhaust system, ensuring all connections are tight and properly aligned.
  • Start the engine to ensure there are no leaks and to enjoy the new sound.

3. Performing an ECU Tune

An ECU tune can be done using a handheld tuner or by visiting a professional. Follow these steps if you’re using a tuner:

  • Connect the tuner to the OBD-II port of the vehicle.
  • Select the performance tune option and follow the prompts to upload the new settings.
  • Disconnect the tuner and start the engine to ensure it runs smoothly with the new tune.

4. Installing Performance Headers

Installing performance headers can be more complex but is worth the effort. Here’s how to do it:

  • Remove the old exhaust manifold by unbolting it from the engine.
  • Install the new headers, ensuring a proper fit and sealing any gaps.
  • Reconnect the exhaust system and check for leaks.

5. Upgrading to a Lightweight Flywheel

Finally, consider upgrading to a lightweight flywheel to enhance throttle response:

  • Remove the transmission from the vehicle.
  • Take off the old flywheel and replace it with the lightweight version.
  • Reinstall the transmission and ensure everything is secure.

Expected Results and Performance Gains

After completing these modifications, you can expect to see an increase in horsepower and overall performance. While the stock Mazda Protege5 produces around 130 horsepower, these upgrades can help you achieve or even exceed that figure. The combination of improved airflow, enhanced exhaust flow, and optimized tuning will result in a more responsive and enjoyable driving experience.

Conclusion

The Mazda Protege5 is an excellent platform for those looking to enhance their driving experience without spending a fortune. By implementing simple modifications such as a cold air intake, performance exhaust, ECU tuning, headers, and a lightweight flywheel, you can unlock the potential of this compact hatchback. With careful planning and execution, your $2,000 Mazda Protege5 can reach 130 horsepower and provide a thrilling ride for years to come.
