Well, I can't really TELL you what to do to it. I'm guessing it's really your car, but either way, here are some suggestions:
Rims (16-17")
Coil-overs/Springs (I'd lower it about 2 inches)
Exhaust (Full cat-back, not just a muffler)
Intake (CAI)
Those are some of the early mods that I put on my car. It will give your civic a lot more style and won't make it ricey.
OR...you could leave the exterior 100% stock, turbo the engine and have a sleeper
Just my
