We spoke with and listened to BMW tuners, racers and owners. It turned out what they wanted was fast spool, OEM reliability, and a lot more top end HP. With ZERO CORE CHARGES. Proven on the world stage endurance race circuit, and using 100% OEM components from the original manufacturer – these are some of the finest bolt-on turbo upgrades to come through Full Race since our inception in 2003.

Full-Race’s BMW S55 twin turbos are purpose built, a stock-appearing and stock-location performance upgrade.  A true plug and play bolt-on from the OEM manfuacturer, nobody can visually tell these are not OEM without measuring upon disassembly. Utilizing a larger Mar-M turbine wheel with billet compressor wheel – large airflow increases allow for strong topend gains.

Manufactured with validated components from the OEM supplier MHI (Mitsubishi Turbo) – 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. For maximum gains, a custom tune is recommended.
