Mike, its hard to say exactly what each mod nets power wise, but here is a
list of mods I would recommend anyone to consider in stages:

1 - filter, advance timing, and free flow exhaust, a good gain in midrange
and top end power

2 - uprated cam, this will help take advantage of the stage 1 mods above, IME
this will net about 130hp in a 2.2.

3 - port head, intake manifold, install bigger displacement bottom end, which
is what I really recommend for you in the long run, motors can be had these
days for a song.  This is about all you can do in one of these cars before it
starts getting expensive and diminishing.

HTH,
Javad
