Turbosmart IWG75 BW B1 Twin scroll 14 PSI

The Turbosmart IWG75 BW B1 Twin scroll 14 PSI is an upgraded internal wastegate actuator developed to provide the maximum possible boost response for your factory frame turbocharger. Designed as a premium high-performance replacement for OEM equipment, it offers a broader boost and torque curve by achieving peak boost earlier in the RPM range and holding it longer.

Key Features

• Increased working ratio for improved boost response throughout the RPM range
• Large effective surface area diaphragm paired with performance springs for greater leverage
• Durable, high-quality billet construction providing maximum reliability
• Allows manual spring rate changes to fully control your custom boost curve

Fitment

• BorgWarner EFR B1 frame twin scroll turbochargers
• Equipped with a 140mm rod assembly and rated at a baseline pressure of 14 PSI

Note: Fitting a heavier wastegate actuator spring may cause a higher than expected increase in boost pressure; custom tuning and recalibration are highly recommended post-installation.
