Hey everyone. I want to modify my 2.4L Eclipse but I don't know where to start. I don't want to just put an exhaust on it and do just that. I want to get some horsepower out of it and tune it right, if anyone can help please let me know. I should also add I'm not sure what the sub model is, I know it's a 2003 Mitsubishi Eclipse, but it's not the GSR, my car is automatic. Again, help if you can please.
