VTT-FAB Top-Mount Single Turbo Kit

For BMW F8X S55 Platform

VTT-FAB is proud to offer the premiere top-mount single turbo kit for the BMW F8X S55 platform. This system is 100% made in the USA at our Hayward, CA facility using only premium materials and components.

The heart of the kit is a hand-fabricated 321 stainless manifold with billet flanges for maximum flow and long-term durability. It’s paired with our factory-controlled external wastegate system featuring a Turbosmart 60mm Straight Gate. This design gives you complete wastegate control directly through your factory ECU tune — no external boxes, MAC solenoids, or vacuum lines required. Simply reuse your factory actuator with our adapter, and you have a true boost range from 0 PSI to the limits of your turbocharger.
