Description
Elevate the performance of your BMW F90 M5 or F91–F93 M8 with the VTT GC and GC+ Turbocharger Upgrade—the most advanced, drop-in solution available for the F9X platform. Whether you're targeting 1000 WHP or pushing beyond 1300 WHP, these turbos deliver unmatched power, efficiency, and reliability without the drawbacks of traditional hybrid or modified stock units.
Unlike many upgrades that repurpose factory housings with oversized wheels, VTT developed fully new, OE-quality castings to eliminate design bottlenecks. This allows for true performance gains while maintaining direct compatibility with your factory oil, water, downpipe, and charge pipe systems—making installation straightforward and reversible.
Choose from two performance levels:
-
GC Turbocharger: Designed for up to 1000 WHP, based on Garrett G25-660 sizing.
-
GC+ Turbocharger: Designed for 1300+ WHP, based on Garrett G30-900 sizing.

Recommended Supporting Modifications:
To fully realize the power potential of your GC or GC+ turbos, we recommend the following upgrades:

High-performance downpipes and intercooler

Optional VTT F9X BOV Kit (Highly Recommended)
The factory F9X platform lacks a dedicated boost venting system, relying solely on Valvetronic for throttle modulation. Under high boost, this can lead to compressor surge and long-term turbo damage. VTT’s plug-and-play BOV kit provides a complete solution:
Kit Includes:
-
VTT Billet BOV Flange – CNC-machined for perfect fitment
-
Turbosmart RacePort BOV – Ultra-fast, high-boost-capable valve
-
Electronic BOV Controller – Tunes venting based on throttle and boost
-
Plug-and-Play Harness – No splicing or cutting required
Protect your turbo investment and ensure smooth operation under extreme performance conditions.
Vehicle Fitment:
-
BMW F90 M5 – All model years
-
BMW F91 / F92 / F93 M8 Coupe, Convertible, Gran Coupe – All model years
Important Note on Boost Limits
The F90 platform has a factory boost cap of 38 PSI. Exceeding this threshold voids all warranty coverage and risks turbocharger failure. Warranty claims require datalogging verification.
Upgrade With Confidence
The VTT GC and GC+ Turbocharger Upgrade is the definitive choice for BMW enthusiasts chasing serious horsepower. With OEM fitment, zero compromises in quality, and best-in-class performance, this kit redefines what’s possible from a drop-in turbo solution for the F9X M5 and M8 platforms.
