If you view the OS Giken LSD application list, you'll see zero NEO (HD) models being offered: http://www.osgiken.net/products.php?product=lsd

Though there is no break-in period and no figure 8s necessary with the TCD, are you following OS Giken's recommendation to swap out the initial differential fluid after the first 500-1000 miles? I used Mobil 1 Synthetic Gear Lube as the "break-in" gear oil for the first 500 miles and I noticed that the differential oil wasn't up to the task as there was minor chatter with the clutch plates. After I replaced the lesser quality Mobil 1 with the OS Giken 80w-250 gear oil, the TCD has been chatter free and performing flawlessly.

Please oh Please tell me that there's enough interest in starting up another group buy?!

I finally got my differential in my car and took it to one of my favorite local roads to gather some initial impressions. There is no official "break in" procedure but I wanted to do some figure 8s in a parking lot and then put some easier miles on it before really hammering it on a track or drift event but even driving at 60-70% I can feel a difference trailing the throttle into faster sweepers and powering out of low speed corners. This road has some very tight and technical corners, is very bumpy and often has gravel from crap falling down the side into the road. With the stock torsen I would get the inside tire to cut loose if I wasn't careful getting on the power through corners with big dips or bumps, now it it completely unaffected and will put the power down smoothly and evenly. I'm excited to put more miles on it and update my findings after truly testing it on the track next month

I never thought the stock diff was "bad" but this is definitely one modification that you never really realize the full value of until you experience it- it completely transforms the car. Just puts the power down anywhere and it gives you more of an ability to throttle steer which is very enjoyable.
