Which clutch disk?
So the car is going in for a rebuild along with going single and e85, and since the motor is getting taken out it would be an easy job to do the clutch.. At the moment i have the ACT S/S with HD pressure plate and the pro-lite flywheel, i am shooting for 450-500 or anything in between . Not sure how much wear my clutch has now but it hasn't given me any problems for the last 5 years and doesn't seem to be slipping yet(unless it just started). The other day i taken my brothers supra fresh out the shop for a drive and he has a 6 puck unsprung...
Took me 3 tries to get going as it was my first time with an unsprung clutch
but i wasn't that hard after you learn, just hated reving it up to start going and that jerk it has, along with chatter under 1k idle, So what i am asking is if i were to get a 6 puck sprung, would it hold out and feel like what i have now? or do i need to get an unsprung and deal with it? I cant afford an Exedy twin/triple right now but maybe next year or if i get into some money somehow .

Personally I love the unsprung clutches. Had a cusco super single that was unsprung. Bit annoying to get used to to begin with, but once I did I loved it. Makes me sad having a sprung exedy now. The chatter becomes less annoying after a little while.

I always figured they were weaker.. I mean there is less material to contact with vs the 6 puck

4 puck have grippier materiel?

Same force over a smaller contact patch. It digs in more. It also wears out your flywheel and pressure plate contact surfaces faster.
I know it seems counterintuitive, but it works. Also the friction material is different.
The reason the sprung disks are more expensive is simply because there are more parts and complexity.

ACT 6 puck sprung, call it a day. You can get a new disk for around $140 with shipping.
Nice thing about race discs is you don't really need to break them in! Just slap it in, slip the **** out of it a bunch of times and you're good to go.
Best method is to put it in fifth from a dead stop, rev it up real high and start slipping the clutch. Do that about five times and let everything cool down and the clutch is broken in.

1. The ACT HD pressure plate with Street Strip disc is rated for 405ft/lbs
2. The ACT Extreme pressure plate with Street Strip disc is rated for 455ft/lbs
3. The ACT HD pressure plate with 6 puck sprung disc is rated for 512ft/lbs
A 450-500whp rotary will make between 400-450ft/lbs. Your current setup will likely slip with your goals. You said you are limited with funds, than swapping in a sprung 6 puck disc is easy as pie. $129 from Rx7store. I took this very route when I turned up the boost. I already had the HD pressure plate, so it was a cheap experiment for a more than capable setup. The sprung 6 puck is not that bad. Yes, it is grabby, but FAR from un-streetable. It wouldn't be my first choice for city driving, but quite manageable.

Clutch failure also comes down to the abuse you put them through. I broke my cusco clutch plate with only 180rwkw on my 200sx. Meant to handle ALOT more power than I was putting out. I clutch kicked the **** out of that car though!! Even smashed steps into the flywheel.
