hands you may want a JDM engine anways. The plus side is.. it'll have everything you'll needs as far as parts to get your started. Down side is... it a used stock motor that and there is always a possibility of failure (BTW- Might have some issues with warranty considering it's for a race application). Also, you'll being paying for emmisions stuff that your going to remove anyways. You may be able to piece together a good engine by making some calls around, but you have to know what your doing otherwise... well.. you know.
Why not buy a used TT with say .. some light body damage and just gut it??
