Pure Turbos BMW N55 Pure500 Stage 1 Turbocharger Upgrade for M2, M135i, 135i, M235i, 335i, 435i
Looking for a proven BMW N55 turbo upgrade that keeps stock-like drivability while unlocking serious performance? The Pure Turbos N55 Pure500 Stage 1 hybrid turbocharger is the perfect fast-spooling, drop-in turbo upgrade for BMW M2, M135i, 135i, M235i, 335i and 435i owners who want reliable power gains without sacrificing daily use. As a UK supplier, Nforcd has fitted and run these turbos extensively, and both our team and our customers love the stealth OEM appearance, rapid spool and repeatable results.
Why choose the Pure Turbos N55 Pure500 Stage 1?
This direct bolt-on hybrid turbo for the BMW N55 is designed to deliver stronger midrange and top-end power with OEM manners. It is VSR balanced to OE N55 specs for smooth operation, uses a larger billet compressor wheel for improved airflow, and retains fast spool for responsive road and track driving. Ideal if you want a dependable, stock-location N55 turbocharger upgrade that works brilliantly on a tuned daily driver or spirited weekend car.
Real-world performance gains
- PWG N55: typical gains of around 50 hp peak and 70 to 80 hp on the top end depending on supporting modifications and tuning
- EWG N55: up to approximately 10 hp on the top end over the stock EWG turbo due to the larger stock EWG compressor
Have an EWG car and want bigger gains? For EWG models we recommend stepping up to the Pure Turbos N55 Stage 2 for a more substantial increase at the top end.
