Pure Turbos BMW N55 Stage 2 Turbo

For the enthusiast hunting for big power out of their N55, this is genuinely the answer. Engineered to reach 500+whp, with proven results as high as 550whp+ depending on chassis and supporting modifications, this turbo utilizes all OEM housings and appears completely unmodified from the outside, great for dealership visits, and a serious step up from a generic TD05 CHRA dropped into stock housings, which is how some competing Stage 2 offerings are built.

Each unit features an upgraded point-milled billet compressor wheel and upgraded HiFlow turbine wheel, with dual compressor and turbine oil seals for genuine sealing integrity under boost. A large-diameter 360-degree thrust upgrade and extensive turbofold modifications and machining round out the package, all VSR balanced for smooth, long-term reliability. Real-world dyno results include 536whp on a 435i, 523whp on a 335i, and 520whp on a 135i.

Genuinely worth pairing: Pure Turbos recommends their N55 High Flow Inlet Pipe alongside this Stage 2 turbo, since the factory inlet pipe is restricted to just a 1.85" inside diameter, a real bottleneck that limits how much benefit you get from the turbo upgrade alone.

Please select the correct wastegate configuration and your specific model at checkout: PWG or EWG core deposit (amounts differ), or send-in-your-turbos option. Silicone inlet pipe kits are also available, specific to E-Series or F-Series fitment.
