need for speed

I was wondering what I could do to add more power to my civic 1.5. I know all the basics, headers, exahust, intake, clutch, but what else can you do that doesnt require major work, i.e drop a turbo in it.

msd ignition cap and rotor and blaster coil would increase ur torque throughout the powerband like the power u have at 1500 rpms u would still have at 4500 rpms end result more giddy up
