Product Description

The Turbosmart TS-0681-5142 IWG75 universal internal wastegate actuator is a versatile performance component engineered to improve boost control on a wide range of turbocharger setups. Featuring Turbosmart's internal wastegate (IWG75) design, this actuator increases the effective diaphragm area and enhances the working ratio over many stock actuators, resulting in a more responsive and stable boost curve throughout the RPM range. The pre-set 14 PSI spring delivers stronger boost response suitable for performance applications while maintaining predictable behavior.

Constructed from high-grade billet aluminum with a durable black anodized finish, the TS-0681-5142 includes a heat-tolerant silicone/Nomex diaphragm and robust stainless steel rod and clevis for lasting durability under demanding conditions. Its 150 mm long threaded rod makes it compatible with many single-port internal wastegate turbo housings, though additional clevis brackets or minor fabrication may be required for installation. The Turbosmart locking collar system also allows easy spring swaps if your tuning or boost goals evolve, making this actuator ideal for custom turbo builds and performance upgrades seeking improved throttle response and consistent boost delivery.
