Also though...when I took the tranny off to put my b16 one on, the throwout return spring was broken so that may have been a part of the reason for the grinding because the clutch always stayed engaged a little. The spring is like 4 bucks at acura and I would recommend replacing it anyways when you put the tranny in. (this part is not internal so I am not saying something is broken in the tranny for those who don't know what I am talking about)
