Information
Standard replacement turbocharger
This original Porsche exhaust gas turbocharger forms part of the twin-turbocharged 3.0L flat-six engine system, helping deliver boost pressure, engine response and factory Porsche performance.
The turbochargers are sold individually, allowing you to replace only the affected side when required.
Fits:
Porsche 991.2 Carrera S / Carrera 4S / Targa 4S 3.0L 2017 – 2019
* engine code: DCH, DCHA
* WITHOUT (X51) Powerkit / WITHOUT (147) Carrera Power kit
Important Fitment Information:
These turbochargers are designed for the 420 PS Carrera S-specification 3.0L engine. They should not be confused with the smaller turbochargers fitted to the standard Carrera / Carrera 4 / Targa 4 models. They are also not the same turbocharger specification as that used on the higher-output 991.2 GTS.
These turbochargers replace earlier Porsche references and are ideal for restoring boost pressure, performance and factory turbocharging reliability with Genuine Porsche quality.
What This Part Does / Functions
• Uses exhaust gas energy to drive the compressor wheel
• Pressurises intake air before it enters the engine
• Helps deliver factory boost pressure and engine output
• Supports throttle response and torque delivery
• Works with the charge air, wastegate and engine management systems
• Replaces a worn, noisy, smoking or failed original turbocharger
• Provides correct Genuine Porsche fitment and specification
• Helps restore original Porsche performance and drivability.
Why Replace This Part?
Turbochargers operate at extremely high temperatures and rotational speeds. Over time, internal bearings, oil seals, turbine components, compressor components or wastegate parts can wear or fail. A faulty turbocharger may cause smoke, loss of boost, rattling, excessive oil consumption, boost control faults or reduced engine performance. Replacing a failed unit with a Genuine Porsche turbocharger helps restore correct OE boost pressure, fitment and reliability for the 991.2 Carrera S 3.0L turbocharged engine.
Common Symptoms of a Faulty Turbocharger
• Loss of boost or reduced engine power
• Blue or white smoke from the exhaust
• Excessive oil consumption
• Whistling, siren-like noise or grinding from the turbo area
• Wastegate rattle or boost control faults
• Check engine light or turbocharger-related fault codes
• Oil leakage around the turbocharger or charge air system
• Poor throttle response or limp mode
• Excessive shaft play confirmed during inspection.
When to Replace This Part
• If the turbocharger has failed mechanically
• If diagnostic testing confirms boost pressure or wastegate faults
• If oil seal failure causes smoke or oil contamination
• If compressor or turbine wheel damage is found
• If the turbocharger has excessive bearing play
• During major engine or exhaust system repairs
• If the turbo has been damaged by oil starvation, contamination or foreign object debris.
Where It Fits on the Car
These turbochargers fit on the engine exhaust / turbocharging system of the Porsche 991.2 Carrera S 3.0L flat-six engine.
9A212303106 fits the left side / cylinders 1–3
9A212303206 fits the right side / cylinders 4–6
Correct side and engine specification selection is essential before ordering.
