Coldside piping
That is the idle speed valve (or something along those lines). It can be removed, but for a street car it probably isn't recommended. I took mine off and made a block off plate. Cold starts are a bitch.
Just swap to an NB style IAC and you'll be fine, that will require that you switch to an NB style throttle body, which only bolts to a 1.8 manifold which only bolt to 1.8 engines. So this is a good excuse to 1.8 swap the car.
