Pure Turbos BMW S55 Stage 2 Turbos

In 2014, Pure Turbos bought an M4 and immediately began R&D to create what's become known as the most powerful and refined turbo upgrade offering available for the S55. Pure dyno tested at 632whp back in 2014, and has since tweaked and tuned the turbos to unleash over 700whp. These S55 upgrade turbos remain the only option available built around purpose-designed S55 compressor and turbine wheel profiles, rather than a generic wheel adapted to fit, making them simply the only proven, powerful, and reliable turbo upgrade available for your M2, M3, or M4.

Each unit features an upgraded billet compressor wheel and upgraded turbine wheel, backed by upgraded thrust bearing with increased thrust bearing surface area for genuine durability under sustained boost. A CNC-ported compressor housing inlet elbow and CNC-machined aerodynamic compressor bullet nose complete the package. It's genuinely no exaggeration to say the world's fastest M2, M3, and M4 builds run Pure Turbos.
