Correct me if I'm wrong, just a quick answer
1. The all-important 'NUR' 3D badge
2. Comes in special Millenium Jade color (and just about most of the r34 colors )
3. Cam cover is Gold in color
4. Should have all items the V-Spec2 have (yellow letters on fuse box, A-LSD, Fins on rear diffs, CF bonnet & ect)
5. Comes in factory 320km/h speedo (300 actually , if not mistaken only Z-tuned and S-tune use the 320 spedo)
6. Brushed silver interior trims including speedo
7. Gold ViN for earlier model , silver/gold for later model
..thats all I can recall
