this is from wikipedia
The cars feature only one engine, a gasoline-powered 2.0 L 4-cylinder E-TEC II made by Holden, developing a maximum power of a 126 hp or 94 kW (US version) or 119 hp or 89 kW (Canadian version) at 5600 rpm.
anyone know what is the difference between the us and can version?I want to know if the 7hp can be recovered easily since I live in canada and may go for the swap
