GC/GC+ Turbocharger Upgrade

The Vargas Turbocharger Technologies GC and GC+ turbocharger upgrades are engineered to replace restrictive factory housings with 100% new, OE-quality castings. Designed to maximize performance on N55 engines, these units feature an upgraded 9-blade Mar-M 246 turbine wheel and point-milled compressor wheels that increase flow while minimizing surge. This drop-in solution allows for factory-like spool and seamless integration with existing engine components. To realize the full potential of these units, the manufacturer recommends accompanying the installation with fuel system, intake, and intercooler upgrades, along with a custom tune to ensure optimal performance. No core charge is required for this unit. This specific part is configured for pneumatic wastegate (PWG) applications only. Note that this component is legal for use only on competition racing vehicles as defined under California law and is intended for closed-course use only. Use on public highways may violate state and federal laws and will void the manufacturer warranty.
