I have a 2004 ZX3 and I have the focussport intake, I put a magnaflow exhaust on it. Is there anything i can do thats no too expensive that will add more horsepower? I know focussport will have the PZEV flash for the computer soon but I am curious if there is anything else I can do.

You could order the Marcy cam adjustment tool and realign those to free up a few more horsies (but it should be done on a dyno) or when you installed the FS intake did you pop out that "honeycomb" looking filter in the MAF? Supposedly that gives it an extra boost as opposed to keepnig it in there.

does that apply to the marcey intake

Yes it applies to the marcy intake. That alone will add about 3 hp. It should be removed with all intakes for the 2.3L

you could also get focus central or draxas header. which gives this car a good change in horsepower and torque.

yeah but living in california it kinda sucks because we have those strict smogs. Adding this stuff will be okay until you have to rebolt your stock parts back on or you get a illegal smog. THats a hassel though so id stick with easier mods for now.
