Subframe conversion bushes, maybe tailshaft change depending if you had ABS tailshaft or not, possibly having to clearance around the knuckle to fit 350Z/GTR driveshafts. It doable but something i was looking to avoid as i have an S13 subframe.
I have a CD009 in my S13 drift car with a 4.36 and it's a little silly but sure makes 250kw feel fast haha
