This is what I have found on the net for the differences from the older 03-05 and the newer 07-08 Ecotec 2.2 liter motors.

The L61 (2.2 Liter) Ecotec has been upgraded for 2007. Changes came from racing experience, upgrades from other families (2.4 Liter and 2.0 Turbo), etc.

Continuous improvement at its best....
