Common Problems with Modified Infiniti G37s and How to Address 100+ Hp-related Issues

by

The Infiniti G37 is a popular choice among car enthusiasts, particularly for those looking to modify their vehicles for increased performance. However, with modifications that boost horsepower by over 100, several common problems can arise. Understanding these issues and how to address them is crucial for maintaining the vehicle’s performance and reliability.

Common Problems with Modified Infiniti G37s

  • Engine Overheating
  • Transmission Slippage
  • Fuel System Issues
  • Suspension Problems
  • Brake Fade

Engine Overheating

One of the most prevalent issues with modified Infiniti G37s is engine overheating. This can occur due to increased horsepower, which generates more heat. It’s essential to ensure that the cooling system is upgraded to handle the extra heat.

  • Upgrade the radiator to a high-performance model.
  • Install a larger oil cooler.
  • Check and replace coolant regularly.

Transmission Slippage

With significant horsepower increases, the stock transmission may struggle to cope, leading to slippage. This problem can result in poor performance and potential damage to the transmission.

  • Consider upgrading to a performance transmission.
  • Install a transmission cooler to manage heat.
  • Regularly check transmission fluid levels and quality.

Fuel System Issues

Modifications that increase horsepower often require more fuel. The stock fuel system may not be adequate, leading to lean conditions and potential engine damage.

  • Upgrade fuel injectors to higher-capacity models.
  • Install a high-flow fuel pump.
  • Use a quality fuel management system to tune fuel delivery.

Suspension Problems

Increased power can lead to handling issues if the suspension is not upgraded. The stock suspension may not provide the necessary support, leading to poor handling and stability.

  • Upgrade to performance shocks and struts.
  • Install stiffer springs to better handle increased power.
  • Consider a sway bar upgrade for improved cornering.

Brake Fade

With increased speed and power, the stock brake system may not be sufficient, leading to brake fade. This can be dangerous and should be addressed promptly.

  • Upgrade to performance brake pads and rotors.
  • Consider installing a brake cooling system.
  • Regularly check brake fluid levels and quality.

Addressing the issues that arise from modifying an Infiniti G37 for over 100 additional horsepower requires a comprehensive approach. Here are some strategies to ensure the vehicle remains reliable and performs optimally.

  • Regular Maintenance: Schedule frequent check-ups to monitor the engine, transmission, and other critical systems.
  • Quality Parts: Use high-quality aftermarket parts to ensure compatibility and reliability.
  • Tuning: Regularly tune the engine to optimize performance and prevent issues.

Regular Maintenance

Regular maintenance is vital for modified vehicles. Keeping an eye on all systems helps catch potential issues before they become serious problems.

  • Change engine oil and filters at recommended intervals.
  • Inspect belts and hoses for wear.
  • Check all fluid levels regularly.

Quality Parts

Using quality aftermarket parts can significantly affect the performance and longevity of a modified Infiniti G37. Cheap parts may lead to failures and additional costs in the long run.

  • Research reputable brands for performance parts.
  • Consult with professionals for recommendations.
  • Ensure all parts are compatible with the G37 model.

Tuning

Tuning is critical for maximizing the performance of a modified vehicle. A proper tune can optimize fuel delivery, ignition timing, and other parameters to ensure the engine runs smoothly.

  • Utilize a professional tuner for best results.
  • Re-tune after any significant modifications.
  • Monitor performance changes and adjust as necessary.

Conclusion

Modifying an Infiniti G37 for increased horsepower can lead to exciting performance gains, but it also comes with its share of challenges. By understanding the common problems and implementing effective solutions, enthusiasts can enjoy their modified vehicles while maintaining reliability and performance.
