IWG75 Porsche 996 (911) GT2 Black 24PSI

turbosmart

The Porsche 996 GT2 Internal Wastegate Actuator (IWG) provides better turbo response and greater sensitivity when managing boost pressures. Designed as a direct bolt-on replacement for the factory part, the Porsche IWG is easy to install and requires no special tools or fabrication. We've taken the proven technology from our WG38, 40 and 45mm External Wastegates and applied it to the Internal Wastegate Actuator.

DesignTek introduces high performance Porsche 996 Turbo and 996 Turbo GT2 intercoolers.

designtek

The intercoolers control the side to side flow design that flows along it's 16inch length. This IC will be more than sufficient for any highly tuned 996TTs or GT2s cars to applications of up to 900hp. DesignTek Porsche intercoolers produces high-flow rate and dramatic temperature reduction which are mainly contributed by two key factors. Firstly, the great temperature reduction is accomplished by a 40% larger than stock sized intercooler cores in which each core has the capacity flow rate of 750 CFM. Secondly, which in our opinion is the most important element of an IC; the inlet/outlet end-tanks. Our end-tanks are optimized to greatly increase air flow and reduce pressure drop which yields to improved efficiency. External aluminium surfaces are preserved with silver/grey protective coating.

The specifications:
- Dimensions Core Thickness: 3.5"
- Core Volume vs. Stock: 40% larger
- Performance Efficiency: 85%
- Flow rate: 620 CFM / side
- Leak Tested: @ 30 PSI
- Pressure Drop: less than 1%

About Turbo Chargers / Intercoolers & Parts

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.
  • Constructed from lightweight, heat-resistant materials.
  • Direct-fit compatibility for Porsche 911, Cayman, Boxster, Macan, Panamera and more.
  • Ideal for performance upgrades, maintenance, or rebuilds.

High-quality turbo and intercooler components are essential for reliable, sustained performance in both road and track environments.

Highlights:

  • Turbochargers, intercoolers & related parts for Porsche models.
  • Precision-engineered to enhance airflow, boost, and cooling.
  • Heat-resistant construction ensures durability and performance.
  • Perfect for maintenance, upgrades, or complete rebuilds.
  • Supports Porsche 911, Cayman, Boxster, Panamera and more.
  • Optimised for performance and reliability under extreme load.
