Product Description

The Turbosmart TS-0625-3143 IWG75 14 PSI internal wastegate actuator is engineered for enthusiasts using the Garrett GT2860RS "Disco Potato" turbocharger or other IWG75-compatible turbo housings. With a pre-set 14 PSI base spring, this actuator provides more assertive boost control than lower pressure versions, making it ideal for tuned engines and high-performance applications where quicker spool and stronger midrange power delivery are desired.

Built from billet aluminum with a corrosion-resistant black anodized finish and equipped with a heat-tolerant silicone/Nomex diaphragm and stainless steel rod, the TS-0625-3143 is designed for durability under demanding conditions. The locking collar system allows you to easily swap in alternative springs if your tuning goals change, while the bolt-on fitment ensures straightforward installation on compatible turbochargers without modification. This actuator is suited for custom builds and high-boost setups where reliable performance and consistent boost behavior are critical.
