"Ok..... after an hour and a bit of digging...... our injector is the same as the Delphi FJ10573 injector used in the 2003-2005 Pontiac Sunfire and Chevy Cavalier
The big difference is that it is rated at 24 lb/hr instead of 19 lb/hr ..... and yes.... that's only a 26% increase in fuel output.... but that's not the point.
I'm sure there are quite a few aftermarket replacement injectors for the Sunfire/Cavalier 2.2L engine...... so you should be able to find the size you need."
Thats from existence's turbo optra build thread, the optra/forenza uses the same injector as the aveo, exact same part number.
