Product Description

The Turbosmart TS-0620-4012 GenV Twin Port Internal Wastegate Actuator is a high-performance actuator designed for use with BorgWarner EFR series turbochargers (including both single and twin scroll B1 & B2 frames). Featuring a true twin port diaphragm design and a GenV cap with reference ports, this actuator delivers superior boost control and a broader tuning window compared to many stock and single-port units. The large working surface area and advanced swivel joint system provide consistent, linear actuation across the boost range, improving throttle response and overall turbo behavior.

Built with a billet aluminum body, a hard chromed intermediate rod, and a reinforced diaphragm, the TS-0620-4012 is engineered for durability under demanding turbo conditions. It includes multiple rods to ensure fitment across different EFR turbo configurations and a set of springs that permit preload adjustment from 5 PSI up to 26 PSI using the Turbosmart locking collar system, making it ideal for street performance or competition-oriented builds. While universal in nature, proper installation and tuning are recommended to maximize the actuator's potential and achieve optimal boost control.
