The Chevrolet Cobalt is a compact car introduced by Chevrolet in 2004 for the 2005 model year. The Cobalt replaced the Cavalier as Chevrolet's compact car.
The Cobalt is available with the SS performance package. There are two engine choices: the naturally-aspirated 2.4 L Ecotec rated at 171 bhp (129kW) and the 2.0 L supercharged Ecotec engine rated at 205 bhp (153 kW). GM currently offers dealer-installed performance upgrade packages called "stage kits" that are covered by factory warranty. The Stage 1 kit consists of new fuel injectors and a reprogram of the ECU, and yields up to a 30 bhp (22 kW) improvement. The Stage 2 kit consists of new fuel injectors and the same reprogram with a smaller serpentine belt and pulley for the supercharger, producing a 40 bhp (30 kW ) improvement and 30 ft·lbf(40 Nm ) of torque. Both stage 1 and 2 kits increase the engine redline to 7000 rpm. The Stage 3 kit consists of a smaller, 76 mm (2.79 in) supercharger pulley, a 2-pass intercooler end plate and a customizable replacement ECU. The Stage 3 ECU allows for the use of a 50-shot of nitrous, 100 octane fuel and an adjustable redline from 6750 to 8000 rpm. Stage 3 produces 248 bhp using 93 octane fuel, up to 260 bhp using 100 octane fuel, and much higher bhp with nitrous. Stage 3 is for off-road use only.
