Product Description

The Turbosmart TS‑0620‑2142 IWG75 Internal Wastegate Actuator is engineered to deliver improved boost regulation and response on turbochargers equipped with BorgWarner EFR B2/B3 series internal wastegates. With a pre‑installed 14 PSI spring, this actuator raises the base boost pressure and enhances control compared to many standard stock actuators. Its billet aluminum housing and Nomex‑reinforced silicone diaphragm are built to withstand the heat and stress of high‑performance turbo applications, making it a solid choice for enthusiasts customizing turbo systems on a wide range of engines.

Designed for universal application with BorgWarner EFR B2/B3 frames, the TS‑0620‑2142 offers a direct wastegate solution that improves sensitivity and regulation. The Turbosmart quick‑change locking collar system allows easy spring swaps for future tuning needs, and pairing this actuator with an aftermarket boost controller enables fine‑tuned boost strategies for street, track, or race builds. While universal in fitment, proper sizing and installation are recommended to ensure optimal performance in your specific turbo setup.
