I found this: http://www.ppi-ats.com/ATS%20350Z%20...utch%20web.pdf

so, would simply replacing the stock slave cylinder with a nismo big slave cylinder fix reliability issues when having a higher pressure plate installed in our cars?

 

good find, maybe some others can shed some light!

 

In for updates

 

Isn't this Nismo slave cylinder for the DE trans and not for the HR? I'm not aware of anyone designing a new CSC for the HR's, aside from the minor adjustments made through the 07 recall. Hopefully I'm wrong.

 

no because that slave is only for use on the older cars, and it's not a Z specific part

 

the .pdf file says its for 350z /"W"HR.....just fyi....

 

That slave is a universal piece NISMO offers for a variety of cars - it is not Z specific. ATS offers it as an option, on their clutch for the HR, which converts the CSC assembly of the 2007 + cars back to the traditional slave scenario found on the 2003-2006 cars. It is not simply an upgraded slave for an HR on it's own, because HR's don't use this type of slave, they are all internalized

yep, and here it is on NISMO's site

so would that nismo slave cylinder need to be adapted to work in an 04 z

 

Zspeed makes the Heavy Duty Slave for the HR, Metal>Plastic

 

I just found this part on line (the Zspeed one) can anyone chime in with real world experience it it is better, longer lasting etc. Also I just got the vehicle (2008 touring coupe) apparently this one has had multiple issues with the CSC, I haven't pulled the transmission yet, and not sure if it has an aftermarket clutch in it or not. Are there any other parts i need to be replacing in there while i have it apart?

Thanks in advance.

 

redline hasnt logged in for 2 years. anyway, i had an 08 and 6 weeks after buying the car (33k miles) it went out, i had the dealership replace for me and they obviously used oem.... fast forward a year and it went out again. i replaced it then with the zspeed hd one, along with the wilwood master and never had another issue. below are what they look like for comparison

oem




zspeed




you can see the obvious differences. where in tx are you?

 

Conroe area, and thanks for the info, I'll order the zspeed one then, is it necessary to replace the master as well, or were you just doing upgrades?

 

they also make another replacement kit, and i am a firm believer in replacing both items together

 

This. ^^^

IMO, if your needs are pretty much street duty with some occasional HPDE, A/X, that sort of thing, there's not much need to go with the Wilwood. Stock works fine with ZSpeed CSC.

But, if you believe all the hoopla about the stock master causing incessant pedal drop, go for the Wilwood or Tilton. (I've successfully used Mac Tilton's products for over 40 years - and have Tilton hydraulics in both of my project Datsuns - so I'm a little biased. )

There is also an alternative to the CSC altogether, also by ZSpeed, called the CMAK which converts the internal CSC to an external slave system similar to the DE setup. Supposedly works well, have not tried it but reviews are good here on my350Z.
