Well...since you volunteered...
Do any of those mods help where I want, i.e. low end torque? Unless there's something miraculously different about these cars, I find things like CAIs to be more about the bling factor than making power. Do they actually make dyno or track proven HP in these 2.0Ls? Again, not looking for miracles, but I'd like a little more go.
Funny aside...since I've taken over driving this one, my wife says I can do whatever I want to it (was off limits before). I told her I was going to stop by the "turbo store" on the way home from work one night.

Ahhh...if only it was that easy.
