I would stick with the teggy *ducks from other civic drivers*
IMO it's a better built car (quality-wise). Sure it'll be slower than a similarly powered civic, I personally would take the slower, more comfortable teg over a civic. Depends on what your goals are of course in the end.
BTW, a 92-95 CX hatch weighs about 2200-2300lbs. I had a JDM B16 in mine before I sold it and it was QUICK, so that C5 in a hatch will be very nice.
