Stage 2 Performance Upgrade Kit
Make that Cobalt SS or Saturn ION Red Line sit up and beg with our Stage 2 Performance Kit. Building on the success of our Stage 1 Kit, our GM Performance Parts engineers wanted to push the overachieving fourbanger just a little bit more. Stage 2 takes your Cobalt SS or ION Red Line from a stock rating of 205 horsepower all the way up to 245 horsepower. The key to making that power is increasing the boost on the factory supercharger by swapping out the stock blower pulley. Increased boost means more air getting pumped into the high-revving Ecotec, and the increased airflow requires more fuel. That’s why GM high-flow injectors are included in the kit. Together, this Performance Kit will keep your Cobalt/ION Red Line boosted ahead of the competition. Please note: premium (93-octane) fuel is required for Stage 2.

Kit Includes:
• High-flow injectors
• Supercharger pulley
• Correct length supercharger belt
• PCM Reprogramming

Stage 3 Kit for Cobalt SS/ION Red Line NEW
Take your Cobalt SS or ION Red Line to the next level with our Stage 3 Off-Road kit! The Stage 3 kit consists of the following:
• Smaller, 76mm supercharger pulley
• 2- pass intercooler end plate
• Unique PCM which includes a calibration for the smaller pulley, an adjustable rev limiter, a 100 octane mode, and a nitrous control algorithm Our Stage 3 kit will take your supercharged Ecotec 2.0L engine to a whole new level of performance. Stage 3 takes horsepower output to 248 hp on 93 octane fuel and to 260 horsepower on 100 octane fuel. In addition to the power increase, you’ll also get an adjustable rev limiter and calibration for a 50 shot of nitrous (nitrous kit not included). For best power, we recommend also installing a high-flow exhaust. This PCM is equipped with a user adjustable rev limit from 6750 to 8000 rpm. The rev limit is adjusted by pressing on the throttle pedal with the ignition on and engine off. At about 50% throttle the tachometer will show the current rev limit. Pressing the throttle further will adjust the rev limit in 250 rpm increments. This PCM is also equipped with a control scheme for the equivalent of a 50-horse shot of Nitrous. The PCM will automatically provide the proper spark and fuel for Nitrous up to 500 rpm below the current selected rev limit when the trigger is activated. The Stage 3 Kit is for off-road use only. The Stage 3 upgrades are meant for off-road use only and are not certified to be emissions legal. The vehicle’s air conditioning is disabled by the Stage 3 PCM. This kit is an upgrade to Stage 2. It requires the following parts from the Stage 2 kit: high-flow fuel injectors, pulley adapter hub, and serpentine belt.
