What clutch is this? 13b or 13btt?
 

I have had this clutch sitting in a sealed box unsprung for many years and want to know what it is as I've had many conflicting opinions on the matter. Thank you.

Looks like the 13bt pressure plate .


^ corrected^

I was told it was an fd twin plate by the person I got it from but you know...

sorry definitely not a pull type clutch (I'm half asleep right now) its for a single turbo engine. The fd pressure plate has the center fun part caved inwards.

Thought so thank you, Kyle Mohan already confirmed this for me but I had to know before I sell it, I'll be back to this rotary life at some point but it's time to pay bills :)

no such thing as a non turbo twin disc clutch so it would have to be turbo, and being non pull type is obviously a FC turbo II clutch set.

Random yet very insightful discussion. I am selling this clutch for 600+shipping, didn't know about the new custom discs but makes this an awesome entry level twin plate for someone looking to do that. I've driven an exedy twin plate and they have a very much stock feel with an aggressive grab. I've driven an HKS twin plate and felt like I was at the gym driving that thing.

Almost makes me want to keep it and go pick up a turbo ii

Many/most of the FD twin plate setups include a conversion to push type throwout bearing, so this could also be an FD part. Should be pretty easy to google the exedy fd twin plate setup and see which way it is...
