Vargas GC+ Turbocharger Upgrade - BMW F90 M5, F9X M8

Product Details

Vargas Turbo Technologies has redefined the "drop-in" turbocharger with the GC+ series for the BMW M5 and M8. Every OEM limitation—from the small inlet restriction to the undersized factory thrust structure—has been eliminated and replaced with proprietary VTT enhancements. The GC+ utilizes a 310 Stainless Steel twin-scroll turbine housing to provide better thermal management and longevity than factory cast iron. Inside, a 9-blade point-milled compressor wheel works in tandem with a Mar-M 246 superalloy turbine wheel to maximize airflow while virtually eliminating compressor surge. This kit includes custom silicone intake pipes with clip-on PCV bungs, ensuring a seamless installation that looks and fits like a factory-installed performance package.

Key Features

• Mar-M 246 Superalloy: High-grade turbine wheel material designed to withstand the intense heat of the S63TU4 engine.

• Anti-Surge Design: Point-milled compressor wheels specifically profiled to minimize surge at high boost.

• Twin-Scroll Design: Retains the factory twin-scroll efficiency for better exhaust gas scavenging and response.
