2. Oil Starvation
Oil starvation can lead to severe engine damage and is a common issue when installing turbo kits. It typically occurs due to inadequate oil supply to the turbocharger, which can result in premature wear or failure.
How to Prevent Oil Starvation
To prevent oil starvation, consider the following:
- Use a high-quality oil with the correct viscosity.
- Ensure the oil feed line is properly installed and free of kinks.
- Install an oil pressure gauge to monitor oil pressure.
3. Electrical Issues

How to Troubleshoot Electrical Issues
To troubleshoot electrical issues, follow these steps:
- Inspect all wiring and connectors for damage or corrosion.
- Check the ground connections to ensure they are secure.
- Use a multimeter to test for continuity in the wiring.
4. Exhaust Leaks
Exhaust leaks can occur at the turbo manifold or between the turbo and exhaust system. These leaks can lead to a loss of power and increased noise levels.
How to Fix Exhaust Leaks
To fix exhaust leaks, take the following actions:
- Inspect all exhaust connections for signs of leaks.
- Replace gaskets that are worn or damaged.
- Use exhaust sealant on connections to prevent leaks.
5. Turbo Lag
Turbo lag is the delay between pressing the accelerator and the turbocharger providing boost. This can be frustrating for drivers and may be caused by various factors, including poor tuning or a mismatched turbocharger.
How to Reduce Turbo Lag
To reduce turbo lag, consider implementing the following solutions:
- Optimize engine tuning for better throttle response.
