The AVO Turbo Kit is a popular modification for the Subaru BRZ, offering a significant boost in power and performance. However, like any aftermarket product, it can come with its own set of issues. This article will discuss common problems associated with the AVO Turbo Kit and provide solutions to help you enjoy a smoother driving experience.

Common Issues with the AVO Turbo Kit

  • Boost Leaks
  • Fuel Delivery Problems
  • Engine Management Issues
  • Turbo Lag
  • Excessive Heat

Boost Leaks

One of the most common issues with turbo kits is boost leaks. These can occur due to loose or damaged hoses and connections. A boost leak can lead to a decrease in performance and efficiency.

How to Fix Boost Leaks

To fix boost leaks, follow these steps:

  • Inspect all hoses and clamps for any signs of wear or damage.
  • Tighten any loose connections.
  • Use a smoke test to identify leaks in the system.
  • Replace any damaged components as necessary.

Fuel Delivery Problems

Fuel delivery issues can arise when the turbo kit is installed, particularly if the fuel pump or injectors are not upgraded accordingly. Insufficient fuel supply can lead to lean conditions and engine knock.

How to Fix Fuel Delivery Problems

To address fuel delivery issues, consider the following:

  • Upgrade the fuel pump to ensure adequate fuel flow.
  • Install larger fuel injectors to meet the increased demand.
  • Check the fuel pressure and adjust as needed.

Engine Management Issues

After installing the AVO Turbo Kit, the vehicle’s engine management system may require recalibration. Without proper tuning, the engine may not perform optimally, leading to various issues.

How to Fix Engine Management Issues

To resolve engine management issues, follow these steps:

  • Utilize a professional tuning service to recalibrate the ECU.
  • Monitor air-fuel ratios to ensure they are within optimal ranges.
  • Consider using a standalone engine management system if necessary.

Turbo Lag

Turbo lag can be a frustrating issue for those who are used to naturally aspirated engines. It refers to the delay between pressing the accelerator and feeling the boost from the turbocharger.

How to Fix Turbo Lag

To minimize turbo lag, consider the following solutions:

  • Upgrade to a smaller turbocharger for quicker spool times.
  • Improve exhaust flow with high-performance headers.
  • Optimize the tuning for better throttle response.

Excessive Heat

Excessive heat can be a concern with turbocharged engines, particularly if the cooling system is not adequate. Overheating can lead to engine damage and reduced performance.

How to Fix Excessive Heat

To manage excessive heat, consider these options:

  • Install a larger intercooler to reduce intake temperatures.
  • Upgrade the radiator for better cooling efficiency.
  • Use high-quality synthetic oil to withstand higher temperatures.

Conclusion

The AVO Turbo Kit can significantly enhance the performance of your Subaru BRZ, but it is essential to be aware of potential issues. By understanding these common problems and implementing the suggested fixes, you can enjoy a reliable and powerful driving experience.
