bolt on questions.
Basically what i want to do is simple mods. Im looking at the srs turbo back exhaust on ebay, and was wondering will i see anygains from this system without tunning? I really want to get my full exhaust, k&n intake, front and rear sway bars...prob the eibach street kit, and maybe a sti intercooler. I have already purchased boost,oil,and egt guages. I just want to know if i need to buy a tuuner first b4 i purchase anything. Id like to just have a 2002 wrx with the power of a sti. Is this possible with the stock turbo? If not where does the turbo really start running out of breath. Im not interested in purchasing a turbo for this car because i have a project car already. I just want it a bit faster and to handle better. Thanks for the replys
