The 350Z's 19x10's have a +30 offset, so they won't fit up front without a spacer. I've seen them on an s14, but not an s13. The S13's wheel wells are smaller than the s14's, so you'll probably have problems fitting them and you're gonna need rubber-band thin tires.
IMO, it'll look terrible. They're so big, it'll be hard to get very low with them. It's gonna look like a donk s13... But if you want do it anyways, make 'em fit right and then take pictures of them for the sake of the community and then sell them for something more properly sized.
Oh and don't froget... they weigh about 30lbs each...
