Been done, seen it in NY one of my old street racing buddies did it after he totaled his Spec-V and didn't want to get rid of it cuz it was a fun car he said so he got a B13 to swap into, he lived in Newburgh when he had it completed, had to swap speedo, harness, computer, hub assemblys to fit the axles, used stock axles he said the hubs bolted right up to the B13 spindles, a-lot of other shit that I don't really remember the details to but it was all pretty much a straight forward except for (if I remember correctly) 1 or 2 mounts had to be custom, he sold it on E-Bay a while ago, but the car was beautiful and fast as shit, all motor with basic bolt-ons and S1 cams he was able to take "DE" 350Zs easily only difficulty if sourcing out the parts you may need because not a lot of people have done this so you will have to custom fab some stuff and space the hood by the hinges cuz he said the intake manifold on the Spec was a bit to tall and hit the hood frame (so either cut that section of the hood frame or do what the Hondas do and lift the hood
