Description
Elevate the performance of your BMW G8X M3/M4 or F9X X3M/X4M with VTT's revolutionary "GC" and "GC+" turbocharger upgrades. Designed to eliminate the restrictions of factory housings without core charges or lengthy lead times, these turbochargers are engineered to perfection. We have retained the exceptional design elements of the factory BMW turbochargers while addressing limitations such as the small factory inlet area, bearing housing oil structure, and thrust bearing. With our proprietary VTT enhancements, these components are cast to OE quality, providing unparalleled performance. The GC turbochargers are direct replacements that support 800-950WHP, maintaining near-factory spool and all factory connections, including oil, water, downpipe, and charge pipe. These turbochargers hold all G8X records for ET and trap speed as of 7/24/22, making them a record-breaking upgrade for your BMW.
Power Levels:
- GC: Stock - 800WHP
- GC+: Stock - 950WHP
Key Design Elements:
- All-new castings with factory restrictions removed—no oversized wheels crammed into factory housings.
- Twin-scroll 310 stainless steel turbine housing for superior heat and corrosion resistance.
- GC 52mm and GC+ 54mm G25 Spec 9-blade Superalloy Mar-M 246 turbine wheel with advanced aero technology for increased flow and optimized spool.

- No core charges—the new unit is sold outright, allowing you to keep or sell your old unit.
- No long lead times—production units available for same or next-day shipping (check stock levels when ordering).
