VTT BMW S55 GC / GC+ Turbocharger Upgrade
The S55 GC platform replaces the restrictive factory-frame architecture with all-new VTT castings and purpose-built rotating assemblies while retaining factory-location packaging and connections.
Power Capability
Supported power range: stock through approximately 800 WHP with the required fuel, airflow, engine, drivetrain, and calibration package.
GC Construction
- All-new 316 stainless-steel turbine manifold/housings
- All-new compressor housings with integrated high-flow inlets
- VTT GC CHRAs with Mar-M 246 G25-profile turbine wheels
- Billet compressor wheels
- Performance-upgraded thrust systems
- Custom VTT silicone inlet adapters
GC+ Compressor Option
The available GC+ compressor option provides approximately 15–20 percent additional compressor flow over the standard GC wheel. Final output depends on calibration, fuel, boost, engine condition, supporting hardware, and operating environment.
No Core Charge
Pricing is for the pair of turbochargers and no core charge is required. Keep or sell the original units.
Fitment and Supporting Systems
Confirm the exact S55 chassis, production year, wastegate configuration, inlet system, and charge plumbing before ordering. A compatible calibration and adequate fuel, intercooling, crank-hub, PCV, engine, and drivetrain support are required.
Warranty
VTT turbocharger systems include a one-year limited warranty. Review the current warranty, installation, oil, and emissions terms during checkout.
Competition Use Only
These parts are legal for use only in competition racing vehicles as defined under California law and are not legal for use in any other motor vehicle. California law defines a racing vehicle as a competition vehicle not used on public highways (California Health & Safety Code 39048). Competition-only vehicles must be operated exclusively on a closed course in conjunction with a sanctioned racing event and transported to the event by trailer or other carrier. Use in any other vehicle may violate federal and/or state law, void the VTT warranty, and void the vehicle manufacturer’s warranty. The purchaser is responsible for compliance with all applicable laws.
