supercharging a 1.5L civic

i'd really like to get some more power out of my ride but don't have to cash to do a swap right now (or the car for doing a swap really) I was thinking about puting a supercharger on because it seems like something i could do in about a day and isn't too expensive if i can find a used one

my engine have about 140K miles on it, which makes me a bit hesitant

anyone have any advice or knowledge about doing something like this.... i'd love to hear it

later
Sean

bad idea
