2021+ BMW M3 M4 S58 G80 G82 Bolt On Twin Turbo Upgrade

Full-Race spoke with, and listened to, BMW tuners, racers, and owners. It turned out what they wanted was OEM reliability, a simple install and more top-end HP (with zero core charges).  Proven in DTM endurance racing and manufactured using 100% OEM components from Mitsubishi Turbocharger, BMW's turbo manufacturer, these are some of the finest OEM+ bolt-on turbo upgrades to come through Full Race since their inception in 2003. 

Full-Race BMW S58s twin turbos are purpose-built, stock-appearing, and stock-location performance upgrade turbochargers.  Nobody can visually tell these are not OEM without measuring upon disassembly. Utilizing a larger Mar-M turbine wheel with a billet compressor wheel, this turbo is designed for reliable midrange and top-end gains.

Manufactured with validated components from MHI (the OEM supplier to BMW) these turbos are proven during multiple 24H endurance races.  Each turbo is hand-built and high speed balanced for maximum reliability and durability.  Wastegate actuators are pre-calibrated for easy installation.  Stock tunes can be utilized with all stock components. A custom tune is recommended for maximum performance.
