Turbocharger. Porsche 991.2 Carrera 3.0L 2017-19  ❭  9A212302

Standard replacement turbocharger
The 991.2 Carrera introduced Porsche's twin-turbocharged 3.0-litre flat-six engine, using a dedicated turbocharger for each cylinder bank. These BorgWarner units provide a direct replacement solution for the original turbochargers while retaining the factory-style boost characteristics, response and drivability of the standard engine.
The turbochargers are sold individually, allowing you to replace only the affected side when required.

BorgWarner Turbocharger Technology
BorgWarner has extensive experience developing turbocharging systems for modern high-performance petrol engines.

The K03.3 turbochargers used on the 991.2 Carrera are engineered to provide rapid boost response together with the airflow required by Porsche's 3.0L twin-turbo flat-six.

Correct turbocharger operation is critical to:
•  Boost pressure control
•  Engine performance
•  Throttle response
•   Airflow delivery
•   Fuel efficiency
•   Exhaust emissions
•   Overall engine reliability

Replacing a failed factory turbo with the correct BorgWarner unit allows the original engine and ECU calibration to operate with the appropriate turbocharger specification.

Signs of a Worn or Failing Turbocharger
A turbocharger operates at extremely high rotational speeds and temperatures. Wear can develop over time due to mileage, lubrication problems, contamination or other engine-related issues.

Possible symptoms can include:
•   Reduced engine power
•   Loss of boost pressure
•   Slow or inconsistent boost response
•   Whining or unusual turbocharger noise
•   Excessive exhaust smoke
•   Increased oil consumption
•   Oil leakage around the turbocharger
•   Boost-pressure fault codes
•   Check-engine warning
•   Excessive shaft play
•   Poor acceleration

Turbocharger symptoms can also be caused by other components, including boost hoses, actuators, sensors, oil supply problems or intake leaks, so correct diagnosis is recommended before replacement.

Important – Diagnose the Cause of Turbo Failure
Before fitting a replacement turbocharger, the cause of the original failure should be identified and corrected.
We recommend inspecting:
•   Turbocharger oil supply and return lines
•   Engine oil condition and pressure
•   Intake system
•   Air filter Charge-air hoses and connections
•   Intercoolers
•   Exhaust system
•   Boost-pressure control system
•   Wastegate operation
•   Crankcase ventilation system
•   Foreign-object damage

Installing a new turbocharger without correcting an underlying oil, intake or boost-control problem can result in premature failure of the replacement unit.
