I have a 2003 RSX (base) and I have installed Megan Racing Cat back, Megan Race Header, and K&N short ram intake on the car. It runs a little bit quicker, but I want to do more to it. Eventually I plan on getting the ECU reflashed (probably next month). I would like to see it get into the 200hp range, and I read online on Yahoo Answers that I should replace the intake manifold.
What about the cams as well, is this something that I should look into? I am not looking to make a race car here, nor a track car. I just want to have a daily driver that drives and handles better than most
