IWG75 Porsche 996 (911) GT2 Black 24PSI



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.

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.

• Original BorgWarner turbocharger as the base part
• TTE Billet geometry compressor 54.5MM inlet
• TTE 9 Blade High-Flow Low-Mass turbine
