Is there a practical way to get good air flow to the back seat of a 96 civic other then rolling down the windows. Reason being is I have a small daughter and the B18 engine swap left me without air conditioning.

I was thinking slap on a front bumper that has sectioned off grills, ie 1 big one for my intercooler and 2 small ones on either side. Then make intake boxes behind the outer grills with lines running under the car and perhaps terminate up and out though the center console. This would just force air into the back of the car rather then AC.

Im open to all suggestions. Something easier would be nice.
