Apparenty the 03+ 350Z clutch fork will work in the 30A with the associated parts clips, pivot ball.

lol… well now the "heavy duty" clutch fork mystery has been revealed.

nice one.

thnx.

----
'''Augustus Maximus:''' (2013-01-27 00:03:03)

I bought the whole shebang for fifty plus dollars shipped to my door. Individually the pieces are quite cheap.

Good info thanks.

----
'''PegCityZ:''' (2013-01-29 15:50:59)

Could you list the part numbers, plz?

----
'''300zxturboftw:''' (2013-01-29 15:58:27)

Make sure you get the right strength pivot ball. It will break on you with these heavy pressure plates if not.

This is where they get you with the optional stuff. Choose according to your clutch kit.

----
'''300zxturboftw:''' (2013-01-29 17:50:06)

Hmmm odd. That pricing really is weird. I guess the dust boot costs around $30. Either way get the chromoly pivot ball. Joe is an awesome guy and you should support him. Very good customer service.

----
'''ZSpeedPerformance:''' (2013-02-27 22:23:56)

Our kit comes with options for chomoly pivot or stock, The price difference is from the pivot ball. If you want a stock pivot ball the base kit starts $42.00, We don't like stock pivots [archived image: wink.png]

----
'''ZSpeedPerformance:''' (2013-02-27 22:26:08)

Mystery? We figured this out 4 years ago and starting offering the kits for the 300z's

Then everyone else followed suit....

----
'''Augustus Maximus:''' (2013-02-28 20:21:04)

After receiving the upgraded fork I threw the other two old style shits in teh garbage. Money well spent.

----
'''-Strike-:''' (2013-02-28 20:41:23)

Wouldn't it be easier to just order the kit they have for the Z31? Or is there something uber cool about the Z33 kit that I don't know about?

----
'''Careless:''' (2013-02-28 21:08:14)

{{Quote|user=|}}

what this thread is illustrating is that the heavy duty clutch fork that zspeed is offering is infact a Z33 clutch fork.

----
'''MADMIKE:''' (2013-02-28 21:58:13)

Nor has it been a mystery.... That would be like saying OMG the SBC upgraded pressure plate is the same as the Z33 Pressure plate.

----
'''Careless:''' (2013-02-28 23:00:06)

{{Quote|user=|}}

the difference is dave advertises the clutch as a modified z33 pressure plate.

zspeedperformance, to my recollection, never indicated what the fork was from- so many didn't know it was from a z33. myself included.

----
'''MADMIKE:''' (2013-02-28 23:05:46)

Cool enough. I bought mine through Zspeed one of the main points of this mod for me was the Cromo Pivot. The Fork is no less important to me, though obviously.

----
'''G-E:''' (2013-03-10 21:53:05)

The cromoly ball wears out regular forks quickly from what I hear, the beefy z33 fork should last a while

----
'''-Strike-:''' (2013-03-10 22:18:00)

I may take the dive and do this upgrade..The time is right to do it, everything is taken apart right now, and the swap would be easy… hrm. Shipping is a bit much, though.

----
'''300zxturboftw:''' (2013-03-11 02:19:21)

{{Quote|user=|}}

If you have a heavy loaded pressure plate i would 100 % recommend this upgrade.

----
'''-Strike-:''' (2013-03-13 17:47:29)

Ordered this morning, they've already shipped. Nice. Shipping is a little spendy for us up here in Canada. But, I am used to paying at least an arm, and most of the time the leg as well.

That's only for my 350z lower staged stuff.. all the Z31 and Z33 SS (aka stage 3) are a 350z pressure plate that is not available from Nissan. They average around 2700lbs of clamp load with no modification. The 'stock' Exedy 350z pressure plates are 1790lbs, my standard modified Exedy is 1910lbs and a blown out Exedy is around 2300lbs. That being said, I have modified the SS pressure plates up to 3800lbs on a 'blown out' version and have held over 800tq.

----
'''flatfoot:''' (2013-04-20 20:49:30)

All right I gathered already it doesn't fit the 71C tranny. Does it interchange between the fs5r30a and and the fs5r90a??

----
'''shromy:''' (2013-04-27 18:40:47)

{{Quote|user=|}}

No. 30a only.

----
'''G-E:''' (2013-04-27 19:05:37)

So maybe I'm lost in all this discussion, if a 71c is only really good at taking say 300tq, you don't exactly need a heavy heavy pressure plate for that, and if you do get a hugely capable clutch in there for a higher power car, aren't you just asking for exploding gears? Shouldn't you be switching to a '30a instead?

----
'''shromy:''' (2013-04-27 19:19:44)

{{Quote|user=|}}

Yes, but 30a can be hard to find and 71c are plentiful enough to blow a few up while looking.

----
'''Augustus Maximus:''' (2013-04-27 20:14:16)

That's why the Z32 easier to find and stronger 30A.

----
'''shromy:''' (2013-04-27 20:22:59)

Speaking of I need to make the time to go get bell housings! The last month has brought a new job. A long commute, looking for a closer residence and even less time [archived image: frown.png].

----
'''G-E:''' (2013-04-27 21:28:41)

OR how about the even more available pathfinder/hardbody trans… that's a direct fit

----
'''Augustus Maximus:''' (2013-04-27 22:48:38)

I'm testing the Maxima setup in the next two weeks. Prepping for the engine hoist as we speak. Let's say I'm kinda curious.

----
'''floridaZ:''' (2013-04-28 14:40:57)

{{Quote|user=|}}

I've never seen anything on the strength of that trans though…

----
'''Careless:''' (2013-04-28 15:30:21)

{{Quote|user=|}}

It's a 30A. It shouldn't differ wildly from any of the other 30A's. Especially since it's moving a heavier car. the Z31 parts for rebuilds are the same as the Pathy ones.

----
'''G-E:''' (2013-04-28 16:51:19)

The only significant difference is the first gear ratio is 2.6x instead of 1.8x… the housing casting is different in that they move the fill hole higher up for extra fluid capacity after realizing the z31 hole is too low heh

----
'''flatfoot:''' (2013-04-29 05:42:39)

To answer my own post about the interchangeability between a 30a and a 90a. For the last 100 miles it appears to be working with Z33 pressure plate and a 240mm flywheel.

----
'''Careless:''' (2013-04-29 06:20:08)

{{Quote|user=|}}

yeah, beck has been saying that for ages. ritter too. beck advised me to fill my transes up to the fill hole, then add another half-litre through the shift lever hole. The transmission that's in the car you came for a ride in was very rough until I started adding more fluid. it's something that really made a difference in that trans specifically. In the one before that it didn't really do much.

----
'''G-E:''' (2013-04-29 06:27:17)

Nissan thought that too, hence the new casting… although they made reference to "heavy duty" … it's still the same transmission, if it's good for one, it's good for the other

----
'''TurboZcaR:''' (2013-04-29 15:48:48)

{{Quote|user=|}}

so you fill your 30a this way? I might have to try this

----
'''-Strike-:''' (2013-04-29 15:52:58)

Hrm interesting. I just received some fresh oil for the rebuilt 30A that will be going in shortly.. I may have to try this..

----
'''G-E:''' (2013-04-29 16:09:39)

I thought about making a spigot for the lower hole (drain) and some kind of filler neck, maybe a hose coupler with a ball valve for easier filling from the top

----
'''RedDemon:''' (2013-04-30 01:28:32)

Is this oil level issue fixed concerning the Z32 30A? Assuming it is if they fixed it on the Pathy

----
'''mkivgen1:''' (2013-06-16 03:25:46)

How do I know if I have a 30a or a 71c? my tranny is from a 86 turbo pretty sure is a borg warner T5. Looks like this one the front part can be removed, will the zspeed fork will fit this tranny?

----
'''Augustus Maximus:''' (2013-06-16 03:56:42)

I used an el cheapo pump from advance auto.

----
'''vgVQ:''' (2015-01-16 20:18:06)

Looks like I will need to do this. Thanks for the info.
