I bought a clutch from an H-T member (Jordo), and everything seems fine, except it's stamped PR3 on the diaphragms..he got it from Kyle at KS-motorsports, for a 2000 Type R...so I assumed it'd be fine for my 95GSR...I'm wondering if he had the wrong one, but since he never installed it, he never noticed..I threw my stock clutch away, so I can't compare
please help

 

All the B series pressure plates bolt up the same but there are at least three variations from FCC who is the OEM manufacturer. The pressure plates function exactly the same and can be interchanged, however stock clutches vary in clamp load. I only have two diaphragm numbers on record. They are P72 (94+ vtec) and PR4 (90-93). Unfortunately I don't have the PR3 on record. The P72 tests about 20% stronger than the PR4. In aftermarket circles, they are interchanged all the time but usually the P72 has replaced the earlier PR4. Now if this is an Action double diaphragm you probably would want to stack two of the weaker diaphragms so the pedal effort doesn't get rediculous.

 

so your saying the PP for the P72 may actually use doubled diaphragms that were used alone on a weaker PP? I guess that makes sense... It came to me new, but not in original packing..I guess the disconcerting part was that Kyle himself didn't seem motivated or interested at all in helping me...What about the disks? would there be differences there?

I am not sure if I understand what you are saying so I will rephrase. All stock B series clutches use a single diaphragm and are interchangable. The diaphragm part numbers I have on record are PR4 and P72 (20% stronger spring). Since you are talking about an aftermarket (Action) clutch which is a modified stock unit, it may be a double diaphragm type which uses two diaphragms stacked on top of eachother. In most cases it is better to stack two of the weaker diaphragms to keep pedal effort under control. I have no information on the PR3 diaphragm part number or anything about a possible Action single diaphragm pressure plate. You may want to call Action clutch. I hear they are really good people to deal with.

~james</TD></TR></TABLE>No differences on B series discs from 92 on up. They changed the release bearing in '94 and then they are all the same, so you are good there too.

 

it's an action 2ks, so it is double diaphragm..what I'm saying basically, is how do I know if this is for a PR3 teg or P72, which would take a different clutch setup if I'm understanding you correctly..

 

You aren't getting the point. Who cares what the diaphragm(s) came out of. As long as it fits the flywheel, it is the right pressure plate. The pressure plates all bolt up the same and the diaphragms work the same.

 

ok, so what makes different clutches different (same maker and model..but for different cars)? Size, bolt pattern, and nothing else? Are all the disks the same? As long as the PP bolts up to the flywheel, your saying there's nothing to worry about with the disk or anything else?

 

why does Action have different part numbers for the B18s and B16s...and why does ACT go so far as to break it down to GSr, non Gsr, etc.. if they're all the same?

 

each aftermarket application is diffrent thats why its broken down, ALL B SERIES (92+) pp's and disk's are interchangable.

and action clutches rule. i had one on my b16. it kicked ***.

No other Honda/Acura shares the same bolt or dowel pattern. Stock B series clutches only vary in clamp load, not in operation. Since you are asking about an Action pressure plate, they are all the same. Why are you trying to make this so difficult? Aftermarket manufacturers list different clutch kit numbers for different years because of the change in release bearings in 94 and in disc splines in 92.
In our catalog we list the GSR seperate from the non-GSR because we list the % of increase. Our part numbers are the same, the torque capacity is the same, but the stock parts we are comparing to are different.

 

I'm not trying to make this difficult, I'm trying to understand what clutch kit I have, so I know the specs of that kit

 

You probably have the dual diaphram pressure plate. Action uses two PR3 diaphrams for the 2MD, 2KS etc clutches. The 1MD B-Series uses a P72 diaphram.

Hope this answers your question.

All 92+ B-Series clutches are interchangeable altough 99-00 SI clutches -only have six holes for the pressure plate bolts (SI's don't have the middle hole of the 3 groups of three holes) where as the others have 9 holes.

 

OK, I think I'm good
thanks alot all..

 

Cool. I hope it works great for you.

 

it will I'm sure, I forgot to mention I have an ACT streetlite too Thought you'd like to know
