VTT-FAB Performance Turbo Kit (Top Mount)

For BMW G8X / F9X S58 Platforms

VTT-FAB is proud to introduce the premiere top-mount single turbo system for the BMW G8X and F9X S58 platforms. Built 100% in-house at our Hayward, CA facility with only the finest components, this kit is engineered to deliver unmatched performance, durability, and simplicity.

At the heart of the system is a hand-fabricated 321 stainless manifold with billet flanges, designed for maximum flow and long-term reliability. Combined with our revolutionary factory-controlled external wastegate system (Turbosmart 60mm Straight Gate), you gain complete boost control directly through your OEM ECU tune — no external boxes, no MAC solenoids, and no extra vacuum/boost lines. Simply reuse your factory actuator with our adapter, and you’re ready for seamless plug-and-play operation with a true boost range from 0 PSI up to the limits of your turbo.

⚠️ Important Notes:

• If your kit shows out of stock, email Sales@VTT for current build times.

• Every VTT-FAB kit is built to order. Once fabrication begins, orders cannot be canceled — please order carefully.
