The K20Z3 in the new Si's is a cool engine since its nearly(197) 200hp from an NA 2.0L but only has 139ftlbs and it doesnt hit until 6100rpm. The Si's are gutless until wound tight(over 6000rpm) and then they fall way out of powerband when you shift unless you let it overrev like 5 or 600 rpm....
The 2.2L has that much torque from about 1200rpm all the way to 6000rpm. The Cobalt SS's LNF 2.0Turbo makes that much torque from barely off idle all the way to redline!(not mention alomst double the peak torque from 2000-5500) The Cobalt SS is gonna smoke the Si( not that the SS/SC didnt already do that
)
I havent heard anything about an NA 2.0 SIDI/VVT

And it`s not torqueless, in 4th, at 2k rpm, touch throttle still as responsive as any 2000cc NA because of i-vtec. Perfectly enough. Possibly more performance than I need.
Honda is the best choice for natural aspiration.
GM is too late to the party, their 140hp 1.8 doesn`t sound so hot anymore especially when the astra isn`t light and the aerodynamics aren't that good, a bit heavier than civic. It`s gotta beat civic if it wants to win.
