Turbosmart TS-0501-3001 Gen4 Diaphragm Assembly O-Ring for ProGate50 PowerGate60

Vehicle Fitment

• Universal - Replacement diaphragm service part for compatible Turbosmart Gen4 external wastegates; not vehicle-specific

Fitment Notes

• Compatible with Turbosmart Gen4 ProGate50 (50mm) external wastegate
• Compatible with Turbosmart Gen4 PowerGate60 (60mm) external wastegate
• Also compatible with the discontinued Turbosmart 6-bolt WG38/45 external wastegates
• Not compatible with Gen4 collared locking collar wastegates (WG38, WG40, WG45 collared variants) - use TS-0505-3006 for those models
• Not compatible with Turbosmart GenV wastegate models
• This is a service/replacement part only - not a complete wastegate assembly

Features

• Factory-spec diaphragm assembly engineered to Turbosmart's original build standards for precise fit and full performance restoration
• Large diameter diaphragm seal provides maximum sealing effectiveness at elevated boost levels, preventing pressure loss or leak-by
• Includes valve guide O-ring to ensure completely leak-free operation at the valve stem interface
• Silicon construction delivers long-lasting durability under sustained heat cycles and high-pressure boost environments
• Restores linear valve travel and consistent boost response, returning wastegate performance to like-new condition
• Hand-assembled at Turbosmart's Sydney, Australia factory under strict quality control procedures
• Tested to the same demanding motorsport standards applied to Turbosmart's complete wastegate range
• Cost-effective rebuild solution - eliminates the need to replace the entire wastegate body

Product Description

The Turbosmart TS-0501-3001 is the factory Gen4 diaphragm assembly and valve guide O-ring replacement designed to service the ProGate50, PowerGate60, and the discontinued 6-bolt WG38/45 external wastegates. Unlike the smaller collared Gen4 models serviced by the TS-0505-3006, this assembly is engineered specifically for the larger 50mm and 60mm wastegate platforms, featuring a larger diameter diaphragm seal that maintains airtight integrity even under the elevated boost pressures these gates are designed to handle.

Over time, exposure to extreme heat cycling and sustained boost pressure will cause wastegate diaphragms to degrade, resulting in boost creep, inconsistent boost control, or loss of wastegate response. The TS-0501-3001 provides a direct path to restoring full function without replacing the entire unit. The included valve guide O-ring addresses the secondary sealing point at the valve stem, ensuring a completely leak-free rebuild from top to bottom. Both components are manufactured to the same specifications as the original parts used in production.

This part is suited to any turbocharged street or motorsport application running a compatible Turbosmart Gen4 large-format external wastegate. It is an essential service item for tuners and builders maintaining high-boost builds where boost control precision is critical. Confirm your wastegate model and generation before ordering - this assembly is not interchangeable with the collared Gen4 WG38/WG40/WG45 variants or any GenV Turbosmart wastegate.
