The NVM BMW N55 Stage 2 Package is a comprehensive performance upgrade bundle tailored for BMWs powered by the N55 turbocharged engine, including models such as the M135i, M235i, 335i, and 435i in the F-series lineup. Rather than selling individual parts, NVMotorsport has put together a full kit of carefully matched hardware, all supplied and fitted with dyno tuning at their headquarters for optimal results.
This package is designed to elevate the performance of an otherwise stock N55 car, targeting around 400 bhp and 640 Nm (on 99 RON fuel) — a significant increase over the factory output without moving into extreme turbo upgrades.
What’s Included in the Stage 2 Package
- Performance Panel Filter: A high-flow replacement filter that maximises fresh air into the engine while maintaining effective filtration.
- Intercooler: A larger, more efficient intercooler finished in ceramic black to help reduce intake air temperatures under load, supporting more consistent power delivery.
- Charge Pipe: Full aluminium charge pipes improve strength and airflow compared with the stock composite parts, helping minimise pressure loss under boost.
- Shielded Decat Downpipe: A performance downpipe with high-grade heat shielding that reduces heat-soak and allows exhaust gases to exit the turbo more freely than the restrictive OEM setup.
- Stage 2 ECU Mapping on the Dyno: Each package includes a live dyno tuning session to properly calibrate the ECU to work with the upgraded hardware for smooth, safe, and powerful performance.
What This Package Delivers
The N55 Stage 2 package isn’t merely a collection of individual parts — it’s a matched performance ecosystem designed to let each component complement the others. Boost response, airflow, exhaust flow, and engine management are all improved in harmony, which results in a noticeable increase in power and torque, smoother throttle response, and a more robust driving experience overall.
By focusing on balanced hardware upgrades plus professional calibration, NVM’s Stage 2 package helps ensure that your N55 engine isn’t just making more power — it’s doing so reliably and consistently, even under spirited use.
