A decent alarm.

Then some UHP tires.

I'd also consider a flow-thru cat instead of a test-pipe, so that you're closer to street-legal.

If you swap the tranny, go with a performance clutch and consider an LSD.

alright, so far what i'm thinking is

manual swap and a good clutch and maybe a lsd and short shifter

an alarm would be a good idea so that people don't steal stuff

and i want to make my stupid tan interior black... carpet dye, black racing seats, (have seat cover on backseat already), headliner kit, new steering wheel (are ebay steering wheels alright?)
just i don't know if i should dye my dash or just get a new one...
does anyone know what dashes and door panelswill fit in my car? such as -will an integra dash fit? or maybe a different gen of civic's interior? or will i have to stick with the same kind of dash i have?
