Anyone know what clutch this is?

I pulled my trans off my SR tonight to put my engine up on my engine stand and found a not so stock looking clutch setup. Anyone know what kind/brand it might be?

Well I finally cleaned all of the crap off of the pressure plate and on one side it says Nismo and on the other it says Exedy when I pulled it apart it was a 6-puck clutch setup. I couldn't find it on the internet so I wonder if they're discontinued?
