Boost Control
The customer will need to supply the boost controller of their choice, as a boost control system is not included with the kit.
For electronic boost control, we recommend using a 3-port or 4-port MAC solenoid controlled through Reflex+. This provides precise and flexible boost management, making it a great option for tuned high-performance S55 setups.
Whether you’re building a responsive fast-road BMW or a serious high-horsepower project, this S55 top mount turbo kit provides the components, airflow, accessibility, and performance potential needed to take your setup to the next level.
