Overview

The Vargas Turbo Technologies GC turbocharger upgrade is a high-performance bolt-on solution for S58 engines, designed to replace restrictive factory units with efficient, custom-cast housings. These turbochargers retain factory oil, water, downpipe, and charge pipe connections while significantly increasing power potential.
Show original supplier description
The Vargas Turbo Technologies GC turbocharger upgrade provides a powerful, bolt-on performance enhancement for BMW S58 engines found in G8X M3/M4 and F9X X3M/X4M models. By eliminating common factory bottlenecks such as restrictive inlets, inefficient oiling structures, and weak thrust assemblies, these units deliver increased airflow and durability. Each kit features all-new castings, a twin-scroll 310 stainless steel turbine housing, and G25-spec 9-blade Superalloy Mar-M 246 turbine wheels for superior heat tolerance and flow performance. The GC version utilizes a 52mm turbine and 58mm compressor, while the GC+ model upgrades to a 54mm turbine and 67mm compressor for even higher output. Please note that while these turbochargers are true bolt-on components, achieving peak performance requires pairing this upgrade with additional supporting modifications, specifically fuel system upgrades, intake, downpipe, intercooler, and professional tuning. Each purchase includes a set of turbochargers and silicone intakes, backed by a 12-month unlimited mileage warranty.
