B, a pretty damn large SMIC will fit the front of a civic or Del Sol without cutting much, if any, of your front bumper away. Leave the bumper rebar in there, and the intercoolers usually mount to that tucking up just below it.
I've seen 24x10x3 intercoolers with a stock bumper, barely shaved. Looks awesome.
