Product Details
The Turbosmart IWG75 Internal Wastegate Actuator Replacement Diaphragm (TS-0600-2001) is a genuine Turbosmart service component designed specifically for compatible IWG75 single-port internal wastegate actuators. Engineered to replace a worn, damaged, or leaking actuator diaphragm, this replacement component helps restore proper pressure response and reliable turbocharger boost control.
The diaphragm is a critical component within a pneumatic internal wastegate actuator. As boost pressure enters the actuator housing, it acts against the diaphragm and internal spring to move the actuator rod. This movement controls the turbocharger's internal wastegate flap, helping regulate exhaust gas flow through the turbine and maintain the desired boost pressure.
Over time, repeated pressure changes, heat cycling, and normal operation can contribute to diaphragm deterioration. A damaged diaphragm may allow pressure to escape from the actuator chamber, preventing the wastegate from responding correctly and potentially causing unstable or excessive boost pressure.
The TS-0600-2001 provides a direct replacement for the original diaphragm in compatible Turbosmart IWG75 single-port actuators, allowing enthusiasts to service their existing actuator rather than replacing the complete assembly.
Whether maintaining a turbocharged Honda K20/K24, servicing an aftermarket turbocharger, or troubleshooting inconsistent boost control, the Turbosmart TS-0600-2001 Replacement Diaphragm provides genuine Turbosmart compatibility and dependable actuator servicing.

Genuine Turbosmart IWG75 Replacement Diaphragm
The TS-0600-2001 is designed to replace the diaphragm inside compatible Turbosmart IWG75 single-port actuators.
Using the correct replacement component helps maintain the intended pressure chamber sealing and actuator response.
The diaphragm is manufactured for the specified Turbosmart actuator family and should not be substituted with an incorrectly sized universal diaphragm.
How an Internal Wastegate Actuator Works
An internal wastegate actuator controls the movement of a turbocharger's internal wastegate flap.
During turbocharger operation, boost pressure is supplied to the actuator through a pressure reference line.
As pressure increases, it acts against the diaphragm and internal spring.
When sufficient force is generated, the actuator rod moves and begins opening the wastegate flap.
Opening the wastegate allows a portion of exhaust gas to bypass the turbine wheel, helping regulate turbocharger speed and boost pressure.
The diaphragm must maintain a proper seal for this system to function consistently.
Importance of Diaphragm Integrity
A damaged or leaking diaphragm can interfere with the pressure signal acting on the wastegate actuator.
Possible symptoms include:
Inconsistent boost pressure.
Unexpected boost spikes.
Overboost conditions.
Incorrect wastegate opening behavior.
Failure to hold pressure during actuator testing.
Air leakage from the actuator housing.
Irregular turbocharger boost response.
These symptoms can also result from other problems, including damaged pressure reference hoses, incorrect actuator preload, sticking wastegate flaps, or boost controller faults.
A pressure test should be performed to confirm diaphragm failure before replacement.
IWG75 Single-Port Compatibility
The TS-0600-2001 is specifically intended for the Turbosmart IWG75 single-port actuator range.
Single-port pneumatic actuators use a pressure connection to control diaphragm movement against the internal spring.
The replacement diaphragm restores the sealing component within the actuator chamber.
Compatibility should be verified using the original actuator's Turbosmart part number.
Important Twin Port and IWGHP Exclusions
The TS-0600-2001 is not compatible with Turbosmart IWG75 Twin Port or IWGHP actuators.
These actuator configurations use different internal arrangements and replacement components.
For supported Twin Port or IWGHP models, Turbosmart offers a separate replacement diaphragm assembly under part number TS-0600-2003.
Do not interchange the two replacement components without manufacturer confirmation.
Replacement Diaphragm vs. Complete Actuator
Turbosmart TS-0600-2001 – Replacement Diaphragm
Replacement diaphragm for compatible single-port IWG75 actuators.
Intended to restore pressure chamber sealing.
Allows servicing of the existing actuator.
Does not replace the actuator housing, rod, or spring.
Does not change the actuator's nominal spring pressure.
Complete Turbosmart IWG75 Actuator
Includes the actuator housing.
Contains the diaphragm and internal spring.
Includes an actuator rod and applicable mounting components.
Provides the complete pneumatic wastegate control mechanism.
Available in different application-specific configurations.
The TS-0600-2001 is intended for applications where the diaphragm requires replacement and the remaining actuator components are serviceable.
Boost Pressure and Actuator Spring Rating
The diaphragm itself does not establish the actuator's nominal boost pressure setting.
The internal spring, actuator preload, wastegate mechanism, and boost control system all influence wastegate operation.
Replacing the diaphragm with TS-0600-2001 restores the sealing component but does not constitute a spring pressure upgrade.
If a different actuator pressure setting is required, the correct Turbosmart spring or actuator configuration must be selected separately.
Internal Wastegate vs. External Wastegate
The TS-0600-2001 is designed for an internal wastegate actuator.
An internal wastegate uses a flap incorporated into the turbocharger turbine housing.
An external wastegate uses a separate valve assembly mounted in the exhaust system.
These designs use different actuator and sealing components.
The TS-0600-2001 is not intended for Turbosmart external wastegate models such as the CompGate40, HyperGate45, ProGate50, or PowerGate60.
