Turbosmart TS-0604-1067 vIWG Vacuum Wastegate Actuator BMW - N20 6inHg

The Turbosmart TS-0604-1067 vIWG (Vacuum Internal Wastegate) Actuator is an upgraded vacuum-operated wastegate actuator designed to provide maximum boost response for BMW N20 turbocharged engines. This bolt-on replacement actuator is engineered specifically for the factory turbocharger fitted to 2.0L BMW N20 (N20A20 and N20B20) engines equipped with a pneumatic vacuum actuator.

Performance Benefits:

• Increased working ratio over factory equipment delivers improved boost response throughout the RPM range
• Larger effective diaphragm surface area provides greater leverage against boost and backpressure forces
• Achieves peak boost earlier in the RPM range and maintains it longer into higher RPM
• Broader boost and torque curve compared to factory actuator
• Dual-port design allows for optional boost-assist configuration with advanced tuning

Construction Features:

• Proprietary silicon Nomex diaphragm for superior durability and heat resistance
• High-grade billet aluminum construction
• Stainless steel rods and clevis for corrosion resistance
• Turbosmart unique locking collar system for secure installation
• Pre-fitted with 6 inHg spring pressure (same as factory base pressure)

Technical Specifications:

• Reference fitting: -3AN swivel banjo in top cap
• Optional boost-assist port: 1/16" NPT (allows twin-port boost control with advanced tuning)
• Direct bolt-on fitment for BMW N20 turbochargers with vacuum actuators

What's Included:

• vIWG wastegate actuator with pre-fitted springs
• Required fasteners and hardware
• Turbosmart decal

This actuator is ideal for enthusiasts looking to improve throttle response and boost characteristics on their BMW N20-powered vehicle. Professional tuning and recalibration is recommended when upgrading to higher base pressures for optimal performance. Not CARB approved; intended for racing applications only.
