![]() ![]() The final stage, Stage 3, is a hardcore ECU reflash and supercharger overhaul, and it even has provisions for meth or nitrous injections. Stage 2 adds an upgraded supercharger pulley, and boosts the output to 245 horsepower. For the supercharged cars, the stage 1 is an ECU reflash and upgraded injectors – adding 25 horsepower, bringing the total to 230. Popular Modificationsīy far, the most popular mods for both the turbo and supercharged cars, is the GM performance parts tunes. Ok, sure it’s technically not aftermarket, but it’s a place to get go-fast bits. The GM Performance parts catalogue offers upgrades and parts, direct from the manufacturer. ZZ Perfomance does tuning for most all GM products, and offer a line of tunes and upgrades for the Cobalt SS. Your local Chevrolet dealer can order OEM parts, namely transmission fluid, or spark plugs. As of the moment, spare parts aren’t that rare to find, despite the Cobalt being out of production for more than a decade now. This car doesn’t require too many specialty parts, so any local online or offline parts store will do. It’s not Volkswagen 2.0T bad, but still it’s something that should be watched for. The Turbo motor has gasoline direct injection, and its semi prone to excess oil build up on the valves. Typically, that means the intermediate steering shaft needs to be replaced. The gearing in the steering shaft can wear on some cars, causing a clunk that manifests itself over bumps. The silver trim on the door handles can flake off in ways that create sharps, even cutting you when you attempt to open the door. This is often accompanied by poor performance and a check engine light signaling bad ignition timing. The “LE5” engine can sometimes stretch out timing chains if not maintained. Timing Chain Issues (Naturally Aspirated, somewhat uncommon).Some owners have reported it either cracking, or popping off completely under higher boost pressure. The charge pipe that feeds into the intake is known for being brittle. Multiple owners have reported boost issues when not using the OEM AC Delco spark plugs. Common in rust-belt states, the fuel line, which runs near the drivers’ side rear wheel well (where water tends to pool) has a tendency to cause corrosion on some models. The European Opel Astra OPC has the same engine as the Cobalt SS turbo. Still, reliability and ownership costs are fairly low for the level of performance the Cobalt SS offers. The brake calipers are also not shared with the regular Cobalt, and are more than double the cost. For example, the wheels are 5×110, which is a bolt pattern shared with few cars. Although the Cobalt SS is a hotted-up Cobalt, many parts are specific to the Cobalt SS. The rest of the car, though? Kind of brittle, and a little bit weird. Both the Supercharged and Turbocharged engines are known for being pretty hardy even when tuned, and the transmissions they’re mated to can take a beating. The Cobalt SS’s reliability is known for being somewhat mediocre, save for the drivetrain. Questionable build quality aside, the Cobalt is a fast and sharp-handling compact car that punches above its weight. In 2008, the engine was traded up for more potent 2.0-liter turbo. In 2005, Chevy took its then-new small car (the Cobalt), slammed in a supercharged 2.0-liter engine, retuned the handling, and added a ground effects kit with a slightly goofy stereotypical Fast & Furious fan wing. Actually, the design’s been aging not-terribly. General Reliability and Ownership CostsĬhevy’s had a fast compact car in its lineup for much of its recent history… some were cool, some not so cool.If you’re looking for something specific, hit command/control-F, type one of these terms, and your browser should bring you straight in.
