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.
