Replacement Wastegate Actuator,for Evo X kit GT/GTX Garrett Turbos running the 4″ inlet comp housing

This replacement wastegate actuator is purpose-built for Evo X owners running a kit-style GT or GTX Garrett turbocharger, giving you a direct, reliable replacement to maintain proper boost control at the wastegate. It’s designed specifically for setups using the Garrett 4″ inlet compressor housing, making it the correct choice for enthusiasts who have moved beyond the stock-style housing configuration. Whether you’re maintaining a higher-boost setup or dialing in a slightly milder tune, this actuator delivers consistent, predictable spring pressure.

Specifications

• Base Boost Pressure: Approx. 18 psi at the intake manifold (without a boost controller)
• Optional Lower Pressure Variant: 12-14 psi
• Compatible Compressor Housing: Garrett 4″ inlet compressor housing
• Actuator Type/Color Options: TiAl Brand (Black Canister), Garrett Brand (Silver Canister)

Performance & Application

This wastegate actuator is engineered for Evo X applications running kit-style GT/GTX Garrett turbochargers equipped with the 4″ inlet compressor housing. It provides a dependable baseline boost target for enthusiasts without a standalone boost controller, while remaining compatible with boost controller setups for finer-tuned power delivery. The optional lower-pressure variant is well suited for builds targeting a milder baseline boost curve, while the standard variant supports higher-boost applications. This actuator is intended strictly for the Garrett 4″ inlet housing configuration, not the stock-style Evo X compressor housing.

Compatibility & Fitment

• Evo X kit GT/GTX Garrett Turbochargers running the Garrett 4″ inlet compressor housing
• Not compatible with stock-style Evo X compressor housings featuring a 3-bolt inlet and 2-bolt outlet

Frequently Asked Questions
