As the title says. Converting to BNR stage 3 now and I'm worried that my OEM 60k km clutch might not like it as much

I'm planning to just buy new clutch/pressure plate, not flywheel as I'll change it while the engine is in the car.

Thinking about the Exedy stage 1 organic disc and uprated pressure plate on MazdaTrix, but it doesn't say any hp/torque specs. Is it any good?

Any input appreciated.

What kind of boost do you plan to run?

OyvindRX-7

Between 12 and 15 psi I guess.

Many people run the ACT street clutch HDSS and I do as well it is awesome and much better than the 6 puck clutch I had. You'll have to find what fits your power level, plenty of threads on here about what clutch with what power level.

I am at 270HP and this is the clutch I run.

Better in what way?

A full disc clutch like the Street/Strip will give you much better driveability. You must start looking at torque ratings here.

An ACT sprung 6 puck with Heavy Duty pressure plate is rated for 512 ft/lbs. This is what I run now, shooting for 500whp. It is a very grabby disc, as all pucked clutches are. Stop and go traffic can become very frustrating as they do not like to slip during engagement. Definitely not recommended until you start making mid to high 400's.

I ran a ACT Street/Strip disc with Heavy Duty pressure plate at 386whp on my previous setup. The clutch pedal is a little heavier due to the pressure plate, but the full face disc drives like stock. Very driveable and perfect for the street. This setup is rated for 405 ft/lbs. Anything in the mid 400's and lower will work great for this setup. It's a very tried and true clutch combination in the community.

I have no experience with the combo you posted. ACT lists torque specs on their sites for their combinations of disc and PP.

We only use the Exedy Stage 1 on cars with basic mods (DP, CB) running stock boost. The ACT HDSS is a much better option for your mods and boost level. The flywheel can be changed while the engine is in the car, that should not be a determining factor.

The driveability made it way better. I had a six puck and it was not enjoyable to drive around town. When I bought my car it came with the six puck as the previous owner was going to shoot for 500hp. I am looking to achieve 350-400 eventually so I went with the ACT and It is a lot better to drive.

Also I think we are talking about the same clutch and presure plate combo. When I say HDSS I am refering to the heavy duty pressure plate and the street and strip clutch. If you are talking about a different setup I'd like to know what it is so I can compare.

Is that the one you mean? You don't have to change flywheel for that clutch do you?
And good for 402 ft/lbs, I doubt I'll make more torque than that on low boost.

Yes the ZX3-HDSS is the clutch that we would recommend for your power level. The ACT clutches bolt to the stock flywheel. I was just saying that the flywheel can be changed while the engine is in the car if that is something you wanted to upgrade also.

I would also install a SS clutch line while you have everything apart. SS Clutch Lines (93+ RX-7)

Yes, this too is what I am referring to. A great street setup with like stock drive-ability. When the boost went up I just swapped in a 6 puck to gain another 110 ft/lbs of capability.

Yes, a very good choice. You do not have to change the flywheel, but it can need resurfaced when mating a new clutch disc. If there are no serious grooves, than simply sanding out the scorch marks is needed. Otherwise, it may need to be re-surfaced from a shop. At that point, it's nearly as cost efficient to look into upgrading. ACT offers great upgraded flywheels. I am running their aluminum lightweight and it works great for the street.

im about to buy the ACT street/strip clutch and as a kit it comes with the release bearing and pilot bearing , how ever i previously bought an OEM pilot and release bearing . my question is which one would be better to use ?

i dont plan on running any crazy WHP i would like to get my FD up to around 350/370 hp , i would think OEM parts would be the way to go but does ACT make a better bearing or is it really all the same.

thanks for any help

I love the ACT SS clutch for mildly modded cars and driveability. If you just want to do the job once replace the clutch fork while you are in there.

Nobody has mentioned twin discs yet. I have had great experience with them. Nice manners around town, near stock pedal pressure and hold a ton of power. IMO, I good clutch makes or breaks the driving experience.

It's too bad there's no good options between a ACT ss disk and a sprung 6 puck for the 450-500whp range. I personally don't mind a harder clutch pedal, but I hate the on/off BS of 6 pucks.

I've heard installing a Tilton flow control valve does help this though.

Actually, there is. The SS disc with an Extreme pressure plate. Rated for 451 ft/lbs of torque.

ACT Clutch Kit

For street driving, it would handle those power levels.

Likely the same. Either part will supply years of reliability.

For any car that is going to be making over 400whp we recommend installing the Exedy Twin disc, none of the single disk clutches hold up as well. If someone has invested the money to achieve a 450-500whp car, then there is no reason to cut corners on a clutch.
