What exactly are you planning on doing? If you have a turbo already and your housings/rotors are bad, then I don't see why not. But some people like having less miles on all the other parts as well.

I may be misunderstanding what you are seeking but it appears from your second post that you are wanting a j-spec engine just for the rotor housings. If this is the case you can buy two brand new rotor housings for the same price that a j-spec engine will cost you.
As far as the turbo engine being installed into an NA car the manifold is different. NA engines have six intake ports and turbo engines have four. You can build an NA engine using turbo rotor housings but there will be a couple of mods needed to account for the differences between the two types of housings. I forget just now what they are but I believe the turbo housing has a rectangular hole just above the exhaust port that must be closed with a custom made piece of metal. The NA housing has a round hole there that is already plugged with a freeze type plug.

I wish I was driving!
to clarify... You want to take a j-spec block and mount all your NA parts onto it?
Simply: NO
All j-specs are TII engines, and thus the engines are 4 port. Your inatke will not bolt on, and you would lose the 6 port induction benefit (big loss). The TII engines are also lower compression to prevent detonation, which would also make your car slower, and you would need a new ECU to handle the change in compression.
There is other stuff, but this is the most basic list.
