TTE800 upgrade turbocharger for Porsche 993 / 996
Introducing our TTE800 upgrade performance turbochargers based on the original K24 turbochargers to new higher output specification. Offering an upgrade to over 800PS.
Engineered & Enhanced
At the core of our TTE800 upgrade stage is a much larger TTE compressor wheel, chosen because it is highly efficient and creates an extremely high flow for comparative size. Re-Profiled compressor cover to optimised tolerance to ensure maximum compressor efficiency is given.
We CNC mill the exhaust turbine housing to accept a larger 9 blade turbine and shaft.
Special profile 360 deg high-performance motorsport journal bearing is fitted, to remain durable at higher loads with no loss in transient response. The actuator used is sprung OE unit set at 0.8bar crack pressure(1.0bar if wanted)
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 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.
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.
