BMW E46 M3

2000 - 2007 - E46 M3
2002 - 2003 - E46 M3 CSL

We have finalised our Stage One supercharger kit for the E46 M3 and E46 M3 CSL. Our Stage One kit ups the standard power of the M3 from 343bhp (360 for CSL) to approximately 480bhp (approx 490 for CSL).

Sensible tuning at an outstanding price.

The Storm Developments "Stage 1" kit is a quality supercharger conversion for the E46 M3 3.2 S54 engine. This kit has been fully developed and built by Storm Developments UK Ltd and is the first and only supercharger kit designed and produced in the UK for the E46 M3. The aim of the kit was to improve the performance of the already amazing E46 M3 S54 engine whilst maintaining drivability.

Our primary goal was to keep the quality stock feel of the car, retaining its excellent handling characteristics with maximum reliability and improved fuel consumption in mind. Bearing in mind it is still rear wheel drive, Storm Developments have researched the car for considerable time and have initially pushed the car to it's safe traction limit rather than pushing the car to extreme undrivable bhp.

This is a product that has an excellent all round fee and good track day characteristics utilising minimum and easy-to-install high quality DIY parts.
