1. Boost Leaks
Boost leaks can significantly affect the performance of your TD06SL2-20G turbo. They can lead to a loss of power and poor throttle response.
Symptoms of Boost Leaks
- Reduction in power output
- Increased turbo lag
- Unusual hissing sounds
How to Fix Boost Leaks
To fix boost leaks, you can perform a boost leak test using a smoke machine or a DIY pressure test. Inspect all connections, hoses, and clamps for any signs of damage or wear.
2. Oil Starvation
Oil starvation can lead to premature turbo failure. The TD06SL2-20G requires proper oil flow to keep it lubricated and functioning correctly.
Symptoms of Oil Starvation

- Smoke from the exhaust
How to Prevent Oil Starvation
Ensure that your oil supply lines are clear and that you are using the correct oil type and viscosity. Regular oil changes and inspections can also help prevent oil starvation.
3. Wastegate Issues
The wastegate controls the turbo’s boost levels. Issues with the wastegate can lead to overboost or underboost conditions.
Symptoms of Wastegate Issues
- Boost levels are inconsistent
- Check engine light activation
- Turbo overboosting or underboosting
How to Fix Wastegate Issues
Inspect the wastegate actuator and linkage for proper operation. Make sure there are no leaks in the wastegate diaphragm and that it is properly calibrated.
4. Excessive Exhaust Smoke
Excessive smoke from the exhaust can indicate that the turbo is failing or that there is an oil leak.
Causes of Excessive Exhaust Smoke
- Worn turbo seals
- Oil leaks in the intake
- Rich fuel mixture
How to Address Exhaust Smoke Issues
Inspect the turbo seals and replace them if necessary. Additionally, check your fuel mixture and ensure that your engine is running properly to prevent excess smoke.
5. Boost Control Problems
Boost control problems can arise from a variety of factors, including tuning issues or malfunctioning sensors.
Symptoms of Boost Control Problems
- Inconsistent boost levels
- Engine stalling or misfiring
- Check engine light activation
How to Fix Boost Control Problems
Check your engine’s tuning and ensure that all sensors are functioning correctly. Additionally, inspect the boost control solenoid and wiring for any faults.
Conclusion
By being aware of these common issues with the TD06SL2-20G turbo on the MazdaSpeed3, you can take proactive steps to ensure your turbocharger operates efficiently. Regular maintenance and inspections will help you avoid these problems and enjoy the performance benefits of your turbo upgrade.
