Well no the 4x100 is like quarter of an inch closer in or something like that. My girlfriend and her 00 Civic ex has 4x100. However they do make and sell adapters/converters for it, I was looking into them because i have an extra set of 4x114 17's. So I wanted to put them on her car so they wont be sitting around. Look online or on eBay especially They have 4x114.3 to 4x100 converters and 4x100 to 4x114.3. Its basically like a spacer and i have heard alot of good things about them and some bad. Like would they be good for daily driving everything i read says yes. However it is mixed on racing drifting and if they effect the handling of the car. I also hear they change the total offset of the wheels too. Here is a link to some on eBay
eBay Motors: 25mm 4x114.3 to 4x100 Wheel Adapter Honda Acura Toyota (item 260332518682 end time Dec-17-08 00:01:00 PST)
you can find more expensive ones not on eBay. Also even cheaper ones on eBay.
So basically you can order some 4x114.3 rims, But if you want them locally then you could do a hub swap lol but if your doing this you might as well do a 5 lug conversion and get nicer wheels. If i was doing a hub convert i would do 5 lug not a smaller 4 lug pattern lol. So that really leaves it to if you want to get rims local and want them to fit get adapter/spacers..
