The Genuine Porsche Turbocharger PAB145703E / PAB145704D is a replacement forced-induction component for compatible Porsche applications. The turbocharger is responsible for generating the boost pressure and increased intake airflow required for the engine to deliver its intended power, torque, acceleration and response.

Diagram Ref No 1 And 2
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.

UPGRADE TURBOCHARGERS
Introducing Upgrade Turbochargers for the 2.9 TFSI fitted to Porsche models. The ultimate blend of power, fast response, and Plug&Play ease of fitment. Our first upgrade step utilizing the original turbochargers for greater flow and power courtesy of bigger billet inlet compressors & bigger exhaust turbines and cnc milled exhaust and compressor housings to accept the larger wheels.
Performance turbochargers are designed for 700PS but there are restriction on this car example the small single charge cooler, so power of around 600-650 ps on 99ron is to be expected (WAGNER upgrade intercooler is recommended). Upgrade downpipes, sport cats and full exhaust are recommended as upgrades to the turbo intakes and system for max performance.
Equilibrium
Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial numbered balance test result document.

Turbochargers, Intercoolers & Parts – Precision-Engineered Performance for Porsche Engines
A turbocharger increases your Porsche’s power and efficiency by forcing more air into the engine’s combustion chamber, while the intercooler cools that compressed air to improve performance and reliability. Together, these components deliver the exhilarating acceleration and responsiveness that define Porsche engineering.
At Design911, we offer a comprehensive selection of turbochargers, intercoolers, and related components for Porsche models old and new. Manufactured using high-grade materials and advanced balancing technology, our range ensures consistent boost pressure, superior cooling efficiency, and long-term durability under extreme conditions.
Whether you’re restoring a classic 911 Turbo, upgrading a Cayman for track use, or replacing worn components on a modern model, our high-quality turbo and intercooler parts guarantee unmatched performance and reliability.
What Do Turbochargers & Intercoolers Do?
Turbochargers and intercoolers work together to enhance engine power, efficiency, and response.
Core Functions:
- Turbocharger:
Compresses intake air to increase the engine’s air/fuel ratio, producing
greater power.
- Intercooler:
Reduces the temperature of compressed air before it enters the engine,
improving combustion and preventing knock.
- Associated Parts: Turbo hoses, valves, clamps, and cooling lines maintain consistent boost pressure and reliable airflow.
Together, these systems optimise power delivery, throttle response, and engine longevity — key to achieving Porsche’s hallmark driving experience.
Why Do Turbochargers & Intercoolers Fail?
Turbo and intercooler systems operate under extreme temperatures and pressure. Over time, wear and heat cycling can cause performance degradation or failure.
Common Causes of Failure Include:
- Oil
contamination or starvation damaging the turbo bearings.
- Boost
leaks from worn seals, cracked hoses, or gaskets.
- Intercooler
clogging due to debris or oil residue.
- Excessive
exhaust temperatures leading to turbine damage.
- Corrosion or heat fatigue from prolonged high-speed driving.
Symptoms of failure include whining noises, loss of power, blue or black exhaust smoke, poor boost response, or oil leaks around the turbo system. Addressing these early can prevent costly repairs and maintain performance.
