I own both so I figure I would give some input. I had a gs with 10 lbs of boost(n/t now) and it was a fast car but I dont think it would be close to an evo. the fastest recorded 1/4 mile time in a stock evo is 12.9(timeslip was provided and it was witnessed) but most run mid 13s. You can figure that a nicely built eclipse could easily hold with an Evo but with less than a grand in mods the Evo can run low to mid 12s with no problem. Another thing to factor in is the awd which takes its toll after 100mph on an evo. On the track there is no comparison between the two, the evo in stock trim is a beast on a roadcourse and an eclipse would need some heavy suspension and brake work to keep up. Most people dont understand the evo is not a drag car even though many people do drag it.
