German tuner adds a stainless-steel sport exhaust system and remaps the ECU to turn the Cooper S and Cooper S JCW into a serious little sports car.

German tuner Nowack Motors has a tuning program for the Mini Cooper S and the Cooper S JCW to heat things up a little.

The tuning packages, the N210, N230 and N260, are labeled for the horsepower upgrading they represent.

To take the Mini Cooper S's 1.6 liter direct-injection turbocharged power plant up to 210 PS (155 kW) the tuning house gets by with a little ECU tinkering and a free-flow air filer. To bump things to 230 PS (169 kW) Nowack needs to remaps the ECU and also adds a stainless-steel exhaust system.

For the range-topping 260 PS (191 kW), Nowack does much of the above while adding high-performance sport camshafts, an in-house downpipe, and a flow-optimised cylinderhead. Intake flow is also optimized and comes with a performance air filter.

Nowack Motors offers suspension upgrading too for the Cooper S and Cooper S JCW which includes its own sport springs and a complete coilover suspension.

The tuner also makes available a set of 18-inch light alloy wheels wrapped in 225/40 R18 performance tires.
