Pure Turbos BMW S55 Cast 800 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 have since tweaked and tuned the turbos to unleash over 700whp. These S55 upgrade turbos remain the only option built around purpose-built 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.

This Cast 800 version uses a new aftermarket housing (OEM design), so there's no need to send in your stock turbos or pay a refundable core deposit. Each unit features an S55-specific engineered billet compressor wheel and an S55-specific engineered HiFlow turbine wheel, backed by a bulletproof heavy-duty large-pad steel thrust upgrade for genuine durability under sustained boost. Everything is completely CNC machined, including a CNC-ported inlet, and VSR balanced to tolerances better than OE S55 specification. It's genuinely no exaggeration to say the world's fastest M2, M3, and M4 builds run Pure Turbos.
