Infiniti G35 Turbo Conversion: Achieving 350 Hp for Under $3,500

by

The Infiniti G35 is a beloved vehicle among car enthusiasts for its sleek design and performance capabilities. However, many owners seek to enhance their driving experience further by increasing horsepower. A turbo conversion is a popular option for achieving significant power gains, and it can be done without breaking the bank. In this article, we will explore how to achieve 350 horsepower in your Infiniti G35 for under $3,500.

Understanding the Basics of Turbocharging

Turbocharging is a method of forced induction that uses exhaust gases to spin a turbine, which then forces more air into the engine. This process allows for a denser air-fuel mixture, resulting in increased power output. Before diving into the conversion process, it’s essential to understand the components involved and how they work together.

  • Turbocharger: The heart of the system that compresses air.
  • Intercooler: Cools the compressed air before it enters the engine.
  • Blow-off Valve: Releases excess pressure to prevent compressor surge.
  • Fuel Injectors: Must be upgraded to handle increased fuel demands.
  • ECU Tune: Adjusts engine parameters for optimal performance.

Essential Components for the Conversion

To achieve a successful turbo conversion on your G35, several key components are necessary. Below is a breakdown of the essential parts required for the build.

  • Turbocharger Kit: Look for a quality turbocharger kit designed specifically for the G35. Brands like Garrett or BorgWarner offer reliable options.
  • Intercooler: A front-mount intercooler is recommended to effectively lower intake temperatures.
  • Exhaust System: Upgrading to a high-flow exhaust system will help improve turbo efficiency.
  • Fuel System Upgrades: Consider larger fuel injectors and a high-flow fuel pump to meet the increased fuel demands.
  • ECU Tune: A proper tune is crucial for maximizing performance and ensuring engine safety.

Step-by-Step Guide to the Conversion

Now that you have the necessary components, here’s a step-by-step guide to completing the turbo conversion on your Infiniti G35.

  • Step 1: Remove the stock intake and exhaust components to make way for the turbo kit.
  • Step 2: Install the turbocharger according to the manufacturer’s instructions, ensuring all connections are secure.
  • Step 3: Mount the intercooler in a suitable location, typically in front of the radiator.
  • Step 4: Upgrade the fuel injectors and install the new fuel pump as required.
  • Step 5: Reconnect all necessary lines, including oil and coolant lines for the turbo.
  • Step 6: Flash the ECU with a performance tune to optimize the engine for turbo operation.
  • Step 7: Perform a thorough inspection of all components and connections before starting the engine.
  • Step 8: Start the engine and monitor for any issues, ensuring that the turbo is functioning correctly.

Budget Breakdown

Staying within a budget of $3,500 for your turbo conversion is achievable with careful planning. Here’s a rough breakdown of costs associated with each component:

  • Turbocharger Kit: $1,200 – $1,500
  • Intercooler: $300 – $500
  • Exhaust System: $400 – $600
  • Fuel Injectors: $200 – $400
  • ECU Tune: $300 – $500

Potential Challenges and Solutions

While the turbo conversion can be a rewarding project, it’s important to be aware of potential challenges that may arise. Below are common issues and their solutions.

  • Boost Leaks: Ensure all connections are tight and use quality clamps to prevent leaks.
  • Engine Management Issues: A proper ECU tune is critical to avoid running lean or rich.
  • Heat Management: Monitor engine temperatures closely, and consider adding an oil cooler if necessary.
  • Installation Errors: Take your time during installation, and consult forums or professionals if unsure.

Conclusion

The Infiniti G35 turbo conversion is an exciting project that can significantly enhance your vehicle’s performance. By following the outlined steps and staying within budget, achieving 350 horsepower for under $3,500 is within reach. Always remember to prioritize safety and reliability during your modifications, and enjoy the exhilarating experience of driving a turbocharged G35.
