Ok, Say you have your every day Civic EX coupe and have $3,000 to spend on making it perform better. What is the best route to go?

Right now I'm thinking this:
Intake/Header/Exhaust
Cams/Cam Gears/Valvesprings, etc from Skunk2
50 shot of Zex

That should put the car around 200hp when on bottle correct? Possibly a little over. Please list your thoughts for/against.

Thanks.
