Hey, well my old car just crapped out on me so im looking around for a new car. Ive seriously considered a 00 civic si but i have some questions. Im getting it for the MPG first off as its my DD, but i also want it to not be completely slow. Id like to eventually supercharge it for some fun, but since in new with boost my question is, how badly does it effect your MPG both when its on and off? Thanks for any help

 

sorry i ment to post this somewhere else, disregard this
