The clutch hydraulic system in the Z just plain sucks. I've had Z1's kit for 2 years now. And still having master problems. I'm in the process of installing the new RJM HD master. I am fully expecting that to solve my problems once and for all.

If you like tinkering with your car and don't mind a little adjusting or part replacing if tracking hard, the Z1 kit is great because you can essentially replace anything in the clutch system without ever having to drop the transmission again (once installed). But if you want maintenance free, 'I don't want to mess with the slave at all', then the ZSpeed HD slave is probably your best option.

Everything JAR said above, and you may also want to insulate the clutch line. You may just be boiling your fluid. Bleeding the system and insulating the line is a cheap easy first step before you drop the tranny.

Hello guys, I think mine will fail in near future too. 2012 / 54k miles on it.
During a mountain run a month ago, I pressed my clutch and it went in all the way. However, it did not come back up all the way. But I was able to put it into gears, and the clutch got normal after one hour of driving coming back home. So I bleed the clutch fluid about two weeks ago. Yesterday I started the car and tried to put it into gear. However the clutch went down halfway when no pressure was applied (only the weight of my foot was applied) but pressure was needed to be applied in order to press it down all the way from the half point like always. It eventually became normal after 15 minutes of driving.

From what I read on this thread, I think I need to do something about it before it dies. I asked my mechanic about it and he said it will cost over $2000 including parts and labor to fix the problem. Is it correct? However, I was debating to keep the Z or let it go for another car. So if I choose to keep the Z, what will be the best way to go? Change it to Z1's kit and will it solve the problem? Or buy ZSpeed HD slave like what JARblue said? I don't track the Z and it's my daily driver. I just don't want to worry about it after if I decide to keep the Z.

Thank you and sorry for poor English.

ZSpeed HD CSC or Z1's CSC kit will both solve your CSC issue. The ZSpeed one requires slightly less maintenance. It's probably the one you want.

$2000 seems a bit high, but not completely outrageous. Typically its 7-8 hours of labor for the transmission drop. So figure $80-120 per hour for labor - depending on your region. Then add cost of parts should give you a good ballpark on what to expect pricewise. Typically I see $1200-1500 for CSC replacement, including aftermarket CSC cost. Check out Z1 for pricing if you're near enough to them in Georgia.

I still take it to Nissan for service, but I can bring in my own. Thanks!

I havent been up in this thread in months.. sorry for the misfortune fellas. Get that Zspeed kit or the Z1 setup...

Correct me if I'm wrong but unlike other makes and models the csc IS an internal lubricated part in our cars correct?

Just wondering what you guys think of the new Zspeed CMAK/CSC delete they just released?
I know it is new and nobody probably has it yet, but just wanted to see what people thought compared to the Z1 from the pictures.

I'm not sure you can go wrong with either one. Both are great vendors. And having the slave cylinder outside the transmission is ideal if you ever need to work on it in the future.

Ok I'm sure I will get negative feedback, but it seems that when I have the VDC in "off mode", my clutch pedal doesn't seem to be as spongy at higher temperatures as opposed to when I have VDC "on".
I can't figure out how this would effect clutch pedal, but clutch pedal has recovered faster & feels less spongy when VDC is in off mode. I don't recommend turning VDC off when driving on wet road conditions.

So the Z1 CSC Elimination Kit, RJM HD Master cylinder, Whiteline diff bushings and Wavetrac LSD have been installed and have definitely rectified any inconsistencies/sponginess in the clutch. My Z is running tight!

awesome man!:driving::driving:

Oh, and thanks for all the great information and suggestions fellas :tup:
