3BCNeed help identifying clutch

[yellow_jacket]

I pulled the pressure plate and disc off of my RB25 today and I found a NISMO clutch disc and pressure plate. The disc has the numbers RS243BC. The Pressure plate has two sets of numbers- NISMO4B26 and then below it is stamped 30210-RS245.

Is this an upgraded clutch? If so what is it rated for? Thanks for the help guys.

Well, a member of another board told me that it has a clamping force of 9,088 newtons. I would really like to reuse this as it appears to be almost new. I will probably go ahead and reuse it just to see what kind of power it can hold.

In other news, I finally got around to removing the broke ez out from one of the broken exhaust studs and removing a broken drill bit from the other. Moral of the story, don't use worn out bits that require you to push hard because they are so dull. I even managed to get one of the two broken studs out. Now I just need to get another ez out for the remaining stud and then I can install the manifold and the turbo. Little by little I will get this done!
