Designed to operate under extreme temperatures and rotational speeds exceeding 200,000 RPM, the turbocharger is one of the most highly engineered components within the engine. BorgWarner's advanced manufacturing processes, precision-balanced rotating assemblies and high-temperature materials ensure rapid boost response, maximum efficiency and exceptional durability.
Whether you're replacing a worn turbocharger, repairing boost-related faults or restoring factory performance, this BW turbocharger provides OE-quality fitment and uncompromising performance.
What Does the Turbocharger Do?
The turbocharger increases engine performance by using exhaust gas energy to compress incoming air before it enters the engine.
This allows the engine to:
- Produce significantly more power and torque.
- Improve throttle response.
- Increase engine efficiency.
- Deliver strong acceleration throughout the rev range.
- Maintain performance at higher engine speeds.
- Improve combustion efficiency.
The Porsche 991 Turbo's twin-turbocharged flat-six relies on precision-engineered turbochargers to deliver its exceptional performance while maintaining everyday drivability.
Why Do Turbochargers Fail?
Although designed for long service life, turbochargers can
eventually wear or become damaged through:
- Bearing wear caused by high mileage.
- Oil contamination or insufficient lubrication.
- Foreign object damage.
- Excessive heat cycling.
- Oil seal deterioration.
- Carbon deposits restricting variable geometry mechanisms (where applicable).
- Overspeed caused by boost control faults.
Regular oil changes using Porsche-approved lubricants are essential for maximising turbocharger lifespan.
Symptoms of a Failing Turbocharger
Common warning signs include:
- Reduced engine power.
- Loss of boost pressure.
- Whining or siren-like noises.
- Excessive exhaust smoke.
- Oil consumption.
- Check engine light.
- Turbocharger fault codes.
- Poor acceleration.
- Boost pressure fluctuations.
Replacing a worn turbocharger restores the engine's original power delivery, efficiency and reliability.
When Should the Turbocharger Be Replaced?
Replacement is recommended when:
Bearing wear is identified. Oil seals begin leaking. Compressor or turbine wheel damage is found. Boost pressure cannot be maintained. Excessive shaft play develops. Turbocharger failure has occurred. Major engine repairs require replacement.Replacing the turbocharger promptly helps prevent debris entering the engine or exhaust system and avoids further costly repairs.
Why Choose a BorgWarner Turbocharger?
BorgWarner is one of the world's most respected manufacturers of high-performance turbocharging systems and an Original Equipment supplier to many leading vehicle manufacturers, including Porsche.
Benefits include:
OE-quality engineering. Precision-balanced rotating assembly. Excellent boost response. Outstanding durability. High-temperature resistant construction. Designed for factory performance levels.

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.
Why Replace Components?
Replacing a worn turbocharger or intercooler with a precision-engineered, high-performance alternative restores full boost pressure, temperature control, and efficiency — ensuring your Porsche performs as intended.
Key Benefits:
- Restores boost pressure and throttle response.
