Just a quick one.
I am just pre planning some mod ideas for a 2009 WRX. It is one of the cars I am looking at getting and would like to see what I am expecting to have to put into it parts and cash wise.
I don't want to have to raise the boost to crazy levels, but a small increase will be fine. I don't want to do any turbo mods. And I would like the engine bay to look as stock as possible.
What I have been looking at has been equal length headers. De-Cat and full exhaust system, doing the up/down pipes. Intake. And of course having it tuned.
But has anybody done just these few mods. And what sort of gains did you get. I also know better brands will give better performance and reliability. I am just looking at this from an on average point of view. For products in the middle of the range perhaps.
I plan on hitting 300hp at the wheels. So with these mods will I make it, if not then what else would I need. I don't really want to go to much over 300whp, since I want the car to be as reliable as possible. And I don't want to have to uprate all the brakes and engine mounts or whatever.
