Check out Unabomber's Manifesto has a ton of info and will prob answer your questions alot faster then waiting on a response. Even though it says no noob bashing people still will or just make smart unhelpful commnets.
Thanks man. And yeah I read the first FAQ but it seemed like it was just a lecture on "do you know how much 400hp really is?" lol
This is going to be my daily driver. Like I said my civic makes 400 but traction sucks. Im trying a wrx b/c its AWD and i do not think I will have any problem putting down the power. not to mention i can keep AC. In all honestly I would be happy with 320 at the wheels. So Im leaning towards the 2.5l STI swap. Can this be done in my 03 wrx for $3000? they are both EJ and im assuming the mounts are all the same.
