For some reason, I remember reading that some first gen B16A's had a different spline count on the shaft coming out of the tranny than other B-series trannies. I'm not sure if that is true or not however (I'm assuming your B16A and tranny are JDM pieces). I haven't worked on a swap like that myself yet. I ran a clutchmasters stage 3 clutch in my '92CX / '95 B18C1 hybrid and I was very happy with it. I used a CM aluminum flywheel too. Here's the link for their site.

I'd consider giving them a call or email them and ask a source directly. I'd recommend you buy from one of their dealers as you'll get a better price but they can probably tell you the best clutch for your application. Sorry I don't have more info.
