I'm guessing that's a EBC solenoid or something to otherwise monitor and control boost. Interesting that they swapped the engines around in the '03+, I know the '94-'02 900/9-3 had the exhaust in the front, and intake by the firewall. They still had a similar box on the WGA, I've always assumed it was for boost control.

Think of it like a BPV versus a BOV. The solenoid cant simply vent metered air with out messing with fuel calculations so they vent it post-MAF as to not loose metered air. There is another nipple on the wastegate that goes to the pressure side somewhere. As mentioned before the Mazda DISI engine uses a similar system.

Yeah. Thats the same boost control solenoid that comes on the efr, that line is labeled vent and they tell you to put behind an air filter because theres a chance you can suck dirty air in somehow. That tube just vents the air that was inside the wga when the noid switches.
If thats the 2.0 ecotec its an odd ball engine. There is two different turbos that could come on it, the "high boost" and normal. Its basically the 2.0 SC engine from eh early cobalt SS's with a turbo on it instead, it was only offered a couple years.
