All this talk about mushrooms and sponges...?
So boys, first things first.
Exhaust...You want to add low to mid power, so find an exhaust that will do that.
Intake...The best intake so far that I have seen is the Injen one.
Not sure if its mushroom or sponge like he said, but it will do the job.
There is a new throttle body out that is 4mm larger than stock by http://www.roadracemotorsports.com/lancer.htm
Suspension...Eibach, the only kit they make. Add a strut tower bar front and rear for help with settling the float in the rear.
