hey i currently have a 2003 chevy cavalier 2.2L with a stage 1 turbocharger kit from Hahn, a magnaflow cat back extaust with a magnaflow high flow converter and a K&N short ram intake. im interested in upgrading my engine units before upgrading to the stage 2 kit. i have had trouble finding a performance intake manifold and throttle body or should i just bore out the stock one? any suggestions please let me know
id say bore your stock TB out. not sure about the intake manifold

Im a Xbox 360 fanboy...and damn proud of it!!
I believe ive seen a Venom Intake Manifold for the Eco b4, altough i could be mistaken.
