- Porsche 971.1 Panamera Turbo 4.0L Twin-Turbo V8 Sport Turismo 2017-20
The BorgWarner Turbocharger is a replacement forced-induction component for compatible Porsche applications. Designed to replace a worn, damaged or failed turbocharger, it helps restore the boost pressure and increased intake airflow required for correct engine power, torque, acceleration and throttle response.

Turbochargers operate at extremely high rotational speeds and temperatures. Correct engine oil supply, cooling, intake airflow, exhaust flow and boost control are therefore essential for reliable operation and long service life.
What This Product Does:
A turbocharger uses energy from the engine's exhaust gases to compress the incoming air supplied to the engine.
Exhaust gases drive a turbine wheel inside the turbocharger. The turbine is connected by a shaft to a compressor wheel on the intake side. As the compressor rotates, it draws in fresh air, compresses it and supplies it to the engine under boost pressure.
Correct turbocharger operation helps:
- Generate the required boost pressure
- Increase intake airflow
- Support the intended engine power and torque
- Maintain strong acceleration
- Provide responsive power delivery
- Maintain consistent forced-induction performance
- Make effective use of exhaust-gas energy
The turbocharger operates as part of a complete system that includes the engine management, intake, intercooling, lubrication, cooling, exhaust and boost-control components.
Symptoms Of Wear Or Failure:
A worn, damaged or failing turbocharger can produce a variety of performance, mechanical and engine-management symptoms.
Common warning signs include:
- Loss of engine power
- Reduced boost pressure
- Slow or delayed boost response
- Poor acceleration
- Inconsistent power delivery
- Engine-management warning light
- Underboost or overboost fault codes
- Limp or reduced-power mode
- Increased engine oil consumption
- Blue or grey exhaust smoke
- Excessive oil in intake or boost pipework
- Unusual whining or siren-like noises
- Grinding or scraping noises
- Excessive turbocharger shaft play
- Compressor or turbine wheel damage
- Abnormal or fluctuating boost pressure
These symptoms do not automatically confirm turbocharger failure. Boost leaks, intercooler problems, sensors, actuators, exhaust restrictions and other engine-management faults can produce similar symptoms.
The system should be correctly diagnosed before replacing the turbocharger.
Why Replacement Matters:
A correctly functioning turbocharger is essential for maintaining the intended performance and operation of a turbocharged Porsche engine.
Replacing a confirmed worn or damaged turbocharger helps:
- Restore correct boost pressure
- Restore engine power
- Restore torque
- Improve acceleration
- Restore throttle response
- Reduce abnormal turbocharger noise
- Address oil leakage caused by internal turbo wear
- Restore consistent forced-induction operation
- Support correct engine-management operation
- Reduce the risk of secondary component damage
A turbocharger suffering severe bearing, shaft, compressor or turbine damage should not remain in service.
