upgrades

Hey yall, im new here, new to owning cars and new to upgrading them. With all this in mind I've been trying to learn as much as i can before making this decision. I'd like to make a build for my 01 eclipse that is the perfect(or as close as it can be) middle ground of fuel economy and drive...

I have a 2001 4g64. Currently, I have a greddy catback, AEM intake, and megan header. I plan on buying the camshaft and valve springs from rpw. Is there anything else i could do to it that would increase my performance?

How's It Going All? I am coming to the user's of Club3G for input. I have seen some of the Mildly Sickest Eclipse's and some of the most Insanely Sick Eclipse's on here. Being in the Marine Corps is one of the most thankless Jobs I have ever seen, i dont make much. Situation: Car - 2003...
