Product Description

The Turbosmart TS-0620-3142 IWG75 Internal Wastegate Actuator is a high-performance actuator designed to improve boost regulation and response on turbochargers equipped with BorgWarner EFR B2/B3 series internal wastegates. The pre-installed 18 PSI spring raises the base boost threshold, offering tighter control at higher boost levels compared to many stock wastegate actuators. Built with a billet aluminum housing, Nomex-reinforced silicone diaphragm, and corrosion-resistant stainless steel components, this actuator is engineered for durability and long-term performance in demanding turbo applications.

The locking collar system from Turbosmart allows for easy future spring swaps to tailor boost control to evolving tuning goals, and pairing the TS-0620-3142 with an external boost controller enables precise boost strategies for both street and track applications. While universal in fitment, this actuator suits a wide range of builds using BorgWarner EFR B2/B3 wastegates and is ideal for enthusiasts seeking improved boost behavior and control on high-performance turbo systems.
