Just traded my 05 mustang gt in on a 09 wrx since I am moving to Alaska due to my job. I plan on future mods but nothing to crazy, just want about 340-350hp at the crank which is what my mustang had. I have no idea about imports or forced induction as all 3 of my past cars have been all v8 power. Just want to know what the good brands for aftermarket are and what is the safest way to add HP to get where I want to be? Thanks any help is appreciated.
