This is a very old thread (~5 years old) and you very likely won't get responses from the original posters in here. From memory, the Nismo ECU set up (with throttlebody, Dizzy, etc.) that GTRHOLIC had got passed around to various people but to my knowledge, did not get installed by anyone.
If yours looks like the dizzy in the above pictures, there may be a very slight chance that it can be used though you'll need an external coil and a bit of knowledge on how to wire it in with the standard ECU if that's your intention.
