Ok, I have been out of the scene for a few years at least and I am starting back at the bottom. My best was a GSR I built that ran 13's and also my S2000.

I have a 2002 Civic EX sedan with 176k miles, to be honest I cannot say I like it and I would rather have something else. But it is good on gas and reliable. Runs strong and no accidents and is a 5spd.

So, can I put the 05 headlights and tail lights on it? What all is required to do that?

Can I purchase headlights already retrofitted for HID?

Can I put a B18C1 in it and what is necessary to do that?

Can I get rear disc brakes?

 

05 Headlights probably requires front bumper, fenders, possibly hood, too. I bet the tail lights are a direct swap.

If someone is selling HID retrofitted lights, why not?

B18c1 in that car? No.

Not sure about rear disc. I bet you can find an 01-05 with rear discs and use that.
