What do i have to do to put up more speed to my impreza..i haven't done anything to it yet..i just bought it..so any suggestion for me..?
not to much,you can put a cold air induction on it,give you about 5 more hp.
try a header, if it's an auto try a shift kit, new fuel pump, larger injectors, new cams, better plugs and wires and an safc tuner.
get your ecu re mapped
do an open source tune!! check out NASIOC and you will for sure find some info on it
