For a long time the only solution for a Porsche 991 GT2 RS intercooler upgrade was not an upgrade, but a band-aid for the stock 1990's style water spray system which sprays water from a reservoir in the frunk and onto the intercoolers. The band-aid was to install a larger capacity water tank which simply delayed the inevitable running out of water and output to be automatically limited by the factory ECU to try to keep the engine safe. Until you refilled the reservoir again it's likely your 991 GT2 RS would struggle with charge temps and limited output.
Experts in cooling CSF and PWR have joined operations to deliver a High-Performance Intercooler Upgrade for the 991 GT2 RS which eliminates heat soak and lowers charge air temps on stock, tuned and tracked cars. CSF achieves this by using an F1 performance grade core which dramatically improves the efficiency of the intercoolers within the same space constraints.
The CSF High-Performance Intercoolers for the GT2 RS boasts 13 more cooling rows than the stock intercooler, boasting 28 rows in total vs. the stock 15. The tube height and fin height is also maximised with the CSF core boasting a dual-row 3mm rolled tube vs. the factory 7mm height and the CSF core uses a fin height of 4.85mm vs. the factory 7mm. As you can see, the CSF core maximises performance in every area.
The differences don't just end in performance. The CSF High-Performance Intercoolers for the GT2 RS also boast reliability and durability improvements. Customer feedback has reported numerous failures with the standard end-tanks which uses an un-secure and failure-prone crimped and gasketed mechanism which can leak over time with numerous boost cycles and increased boost pressure with tuned cars, whereas the CSF High-Performance Intercoolers for the GT2 RS is 100% TIG welded for maximum reliability and durability.

TTE1200 VTG upgrade turbocharger for Porsche 991.2 GT2 RS
Welcome to our TTE1200VTG Upgrade turbocharger stage for Porsche 911 GT2 RS 3.8L 700PS flat-6. To construct a pair of TTE1200 VTG we change the original compressor and employ a far larger and more efficient billet wheel and mill the compressor cover to optimum gap to match the new compressor profile.
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 serial numbered balance test result document.
TTE1200 VTG can be fitted to Any 3.8 but you would need GT2 RS Exhaust Manifolds as turbo flange different, also oil, water lines, charge pipes and intakes
• Original BWTS turbocharger as the base part
• TTE Billet Milled compressor 7+7 BLADE

Water tank
An additional water tank for charge air cooling increases the standard volume by around 9 litres and ensures that the range is significantly extended between water refills.
As a result, this allows the intake air temperature to be cooled for longer, with the objective of achieving maximum power yield.

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.
- Improves air cooling and power delivery.
- Prevents oil and boost leaks.
