The NA D24 is such a turd it needed all the help It could get, so a very low restriction intake with the long runners helped it run as good as it possibly could... Couple the long runner intake with the turbo, you get the low end off boost benefit of the runners and larger intake volume for the better response, and the boost to cram it in there once the turbo spools up. Its a win win. Though without a bigger turbo I don't know how much low end off boost response your going to pic up with the NA manifold, because the turbo becomes a bit of a restriction off boost with the tiny compressor setup.
