Just as much potential as any other 4-banger from the import brands. The Gen I motors in the J-body (Cavalier/Sunfire) was a little harsh. They worked on the balance and it's quite a bit smoother in the new Cobalt. The biggest differance (and what the domestics have always given us) are *overbuilt* motors, no matter what kind they are. For all the tuners, it allows them to make turbocharging kits a little more potent. GM hasn't had to do much to it in the SS version of the Cobalt.
