Pure Turbos BMW N55 Stage 1 Turbo Upgrade (PWG & EWG) for M2, M135i, 135i, M235i, 335i & 435i - BorgWarner-Based, VSR Balanced, Fast-Spool Bolt-On

N55 Stage 1 Hybrid Turbocharger Upgrade for BMW M2, M135i, 135i, M235i, 335i and 435i

Give your N55-powered BMW the response, midrange punch and top-end pull it deserves with this Stage 1 hybrid turbocharger. Built around an OE-grade core with precision-machined housings and a larger billet compressor wheel, it retains factory manners while unleashing effortless performance. Ideal for daily use, fast-road driving and spirited track sessions, this direct-fit unit keeps the sleeper look with a huge uplift in usable power.

We have installed these at MJ Modifications and customer feedback has been fantastic. Owners love the near-stock spool, smooth boost delivery and strong acceleration all the way to the limiter. If you are searching for an uprated N55 turbo in the UK, a BMW performance turbo replacement, or a plug-and-play hybrid for F-series and E-series cars, this is a proven choice.

Key reasons to choose this Stage 1 unit

• OE-quality core for reliability and longevity on tuned daily drivers
• Sleeper factory-style appearance with quick-spooling response
• Oversize billet compressor wheel and reprofiled turbine for higher flow
• Compressor cover precisely machined, high-speed balanced to factory tolerance
• Direct-fit installation that does not require turbofold removal

Real-world gains

PWG variants: typical improvements are around 50 hp peak with roughly 70 to 80 hp at the top end depending on supporting hardware and calibration. Expect sharper throttle, a stronger midrange and sustained power to the redline.

EWG variants: top-end improvements are up to 10 hp over the stock electronic-wastegate unit. Because the factory EWG compressor is already larger, consider the Stage 2 option if you want a bigger step up.

See the dyno graphs in the product gallery for reference.
