please dont go with the d series, weather its single cam or not, their really not worth building for the little performance that ull get outa it especially for not having a rex or older hatch.....personally go with another motor, if ur in a money chrises go with a b20 or h22
If money is a factor then I wouldn't really recommend an H22 swap into a Civic...
