Product Description

The Turbosmart TS-0620-3143 Twin Port IWG75 Wastegate Actuator is engineered to enhance boost control on turbochargers equipped with BorgWarner EFR B2 series (Single and Twin Scroll) frames. With a pre-set 14 PSI internal spring and Twin Port reference capability, this actuator delivers a more responsive, precision boost curve and broader control range compared to standard single-port actuators. Its billet aluminum housing and Nomex-reinforced silicone diaphragm are designed to withstand high heat and pressure environments, making it suitable for performance turbo setups where improved boost behavior is desired.

The Twin Port design allows boost pressure to be managed across two diaphragm chambers, offering greater tuning flexibility and smoother boost transitions. This makes the TS-0620-3143 ideal for enthusiasts running custom turbo builds or modified engines using BorgWarner EFR B2 internal wastegates. The quick-change locking collar system permits easy spring swaps for future performance goals, and pairing with an aftermarket boost controller allows fine-tuned boost strategies for street, track, or competition applications.
