Product Details
The Turbosmart GenV 5 PSI Inner Wastegate Spring (TS-0550-3086) is a genuine Turbosmart replacement and tuning component designed for compatible GenV HyperGate45 45mm and ProGate50 50mm external wastegates. Featuring a 5 PSI spring pressure rating and yellow identification finish, this precision-engineered inner spring allows users to adjust their wastegate's mechanical base boost pressure to suit different turbocharger configurations and performance requirements.
The wastegate spring is a critical component of a turbocharger's boost control system. It provides the mechanical force that keeps the wastegate valve closed until sufficient pressure acts on the actuator to overcome the spring force. Selecting the correct spring pressure helps establish predictable wastegate operation and consistent boost regulation.
The TS-0550-3086 is specifically designed for the inner spring position within compatible Turbosmart GenV 45mm and 50mm wastegate actuators. When installed individually, it provides a nominal mechanical base pressure of 5 PSI (approximately 0.34 Bar).
This spring can also be combined with other compatible Turbosmart GenV springs to achieve higher mechanical base pressure configurations. Its versatility makes it useful for turbocharger system tuning, wastegate maintenance, and performance upgrades.
Whether adjusting boost pressure on a turbocharged Honda K20/K24, configuring a custom B-Series turbocharger system, or servicing an existing Turbosmart external wastegate, the TS-0550-3086 GenV 5 PSI Inner Spring provides genuine Turbosmart compatibility and dependable mechanical boost control.
This product includes one replacement wastegate spring only. It is not a complete external wastegate assembly.

5 PSI Mechanical Base Boost Pressure
The TS-0550-3086 provides a nominal mechanical base pressure of 5 PSI when installed individually in a compatible GenV external wastegate.
The spring applies closing force to the wastegate valve, helping determine the pressure required to begin opening the wastegate.
Actual operating boost pressure may vary depending on exhaust backpressure, wastegate placement, turbocharger characteristics, and pressure reference plumbing.
A 5 PSI spring is useful for applications requiring a relatively low mechanical base boost pressure or additional flexibility when configuring an electronic boost controller.
Compatible Turbosmart GenV Wastegates
The TS-0550-3086 is designed for the standard GenV WG45/50 spring family.
Compatible wastegate models include:
Turbosmart GenV HyperGate45: 45mm external wastegate.
Turbosmart GenV ProGate50: 50mm external wastegate.
These wastegates utilize a common family of interchangeable spring configurations.
Important: The TS-0550-3086 is not intended as a universal replacement for every Turbosmart wastegate. Verify the exact model and spring compatibility before installation.
Yellow Inner Spring Design
Turbosmart identifies the TS-0550-3086 using a yellow finish.
The color helps distinguish the 5 PSI inner spring from other springs in the GenV WG45/50 range.
The inner spring is designed to fit within the designated actuator spring position.
Correct spring positioning is essential for proper actuator operation.
GenV WG45/50 Spring Pressure Options
Turbosmart offers several springs for the standard GenV 45mm and 50mm wastegate platform.
Available spring options include:
TS-0550-3085: 3 PSI Inner Spring – Orange
TS-0550-3086: 5 PSI Inner Spring – Yellow
TS-0550-3087: 7 PSI Middle Spring – Green
TS-0550-3088: 14 PSI Outer Spring – Blue
These springs can be installed individually or in approved combinations to achieve different nominal mechanical base pressure settings.
Compatible Spring Combinations
According to Turbosmart's GenV WG45/50 spring pressure chart, the following configurations are supported:
| Spring Configuration | Nominal Base Pressure |
|---|---|
| 3 PSI Orange Inner | 3 PSI |
| 5 PSI Yellow Inner | 5 PSI |
| 7 PSI Green Middle | 7 PSI |
| 3 PSI Orange Inner + 7 PSI Green Middle | 10 PSI |
| 5 PSI Yellow Inner + 7 PSI Green Middle | 12 PSI |
| 14 PSI Blue Outer | 14 PSI |
| 3 PSI Orange Inner + 14 PSI Blue Outer | 17 PSI |
| 5 PSI Yellow Inner + 14 PSI Blue Outer | 19 PSI |
| 7 PSI Green Middle + 14 PSI Blue Outer | 21 PSI |
| 3 PSI Orange Inner + 7 PSI Green Middle + 14 PSI Blue Outer | 24 PSI |
| 5 PSI Yellow Inner + 7 PSI Green Middle + 14 PSI Blue Outer | 26 PSI |
Note: Additional springs are sold separately. Only manufacturer-approved combinations should be used.
Mechanical Base Boost vs. Controlled Boost
The wastegate spring establishes the nominal mechanical base pressure of the wastegate.
A compatible manual or electronic boost controller may increase boost pressure above this setting by regulating pressure supplied to the actuator.
However, conventional boost controllers generally cannot reliably reduce boost pressure below the effective mechanical base pressure established by the installed spring configuration.
Choosing the correct spring is therefore essential when designing a turbocharger system.
Benefits of Lower Base Boost Pressure
A lower mechanical base boost pressure can provide additional flexibility during turbocharger tuning.
Potential benefits include:
Lower initial boost pressure for controlled testing.
Greater flexibility when configuring electronic boost control.
Reduced boost targets for specific driving conditions.
Additional adjustment range for compatible boost controllers.
Improved control over boost delivery in traction-limited applications.
The actual benefits depend on the turbocharger system, exhaust manifold design, and engine management configuration.
Genuine Turbosmart Spring Compatibility
Using the correct Turbosmart spring helps maintain the intended actuator characteristics.
Incorrectly sized or incompatible springs may cause improper actuator operation, inconsistent boost regulation, or mechanical interference.
Always verify the wastegate model and use approved spring combinations.
Wastegate Spring Maintenance
Wastegate springs should be inspected when servicing the actuator.
A spring that is damaged, deformed, corroded, or incorrectly identified may affect wastegate operation.
Replacing the spring with the correct genuine Turbosmart component helps maintain the intended mechanical base pressure configuration.

Review Turbosmart Instructions: Follow the current GenV wastegate spring replacement procedure.
Allow the Engine to Cool: Never service the wastegate while surrounding exhaust components are hot.
Remove the Wastegate if Necessary: Provide adequate access to the actuator assembly.
Relieve Spring Tension Safely: Wastegate springs are compressed and can release significant stored energy.
Use the Proper Service Tools: Follow Turbosmart's recommended procedure for opening the actuator.
Remove the Existing Spring Configuration: Carefully inspect the actuator components.
Inspect the Diaphragm: Check for damage, wear, or improper seating.
Inspect the Actuator Housing: Verify that the internal components are clean and undamaged.
Install the 5 PSI Yellow Inner Spring: Position the TS-0550-3086 in the designated inner spring location.
Add Additional Springs if Required: Use only Turbosmart-approved spring combinations.
Verify Spring Alignment: Confirm that all springs are properly seated.
Reassemble the Actuator: Follow the manufacturer's recommended procedure.
Secure the Locking Collar: Verify correct engagement and assembly.
Reinstall the Wastegate: Secure all mounting connections.
Reconnect Pressure Reference Hoses: Follow the correct boost control plumbing arrangement.
Check for Pressure Leaks: Inspect the actuator and associated fittings.
Verify Boost Controller Settings: Ensure the controller is configured for the new spring pressure.
Confirm Engine Management Calibration: Verify that the ECU is configured for the intended boost pressure.
Perform Controlled Initial Testing: Monitor boost pressure carefully during initial operation.
Check for Boost Spikes or Creep: Verify stable boost regulation.
Reinspect After Initial Operation: Confirm that the actuator and wastegate remain properly secured.
Important: Wastegate springs are installed under compression. Follow Turbosmart's service procedures and use appropriate tools when removing or installing actuator springs. Incorrect spring selection or installation can result in improper boost control and engine damage.
