FWIW, alot of members have had issues with the Z1 kit, and will recommend ZSpeed.

This. As indicated, the stock concentric slave cylinder (CSC) is located in the transmission bell housing. If you elect to replace it, the transmission will need to be dropped. I would recommend replacing it with the Z Speed CMAK kit, which places the slave cylinder outside the transmission ... meaning that if it ever fails in the future, it is relatively easy to replace without need to drop the tranny. That said, I'm not aware of anyone who has reported problems with the CMAK slave, and the kit has been on the market for several years. Also, if you decide to replace the stock CSC, you should seriously consider replacing the stock clutch master cylinder (CMC) at the same time. It is also prone to failure. In addition, if you want to virtually bullet-proof the clutch hydraulic system, you should consider replacing the stock clutch pedal assembly with the RJM pedal assembly. Like the CMAK kit, it is a proven improvement over stock. Finally, if you gone this far, you might consider substituting the OEM CMC with the Tilton heavy-duty clutch master cylinder that is also available from RJM. Both Z Speed and RJM offer great after-market service and advice. You should reach out to them for advice on how best to proceed.

I have 6000 km on mine, going strong with no issues. Super reliable!

I dont know if any1 mentioned this but heres my 2 cents

Buy a 2014+ Z no early version due to Oil galley leaking issues, also when you tune it due to 100+K miles I suggest to tell your tuner to keep the timing advance normal to low to minimize engine issues, to find a descent engine just check for blow by and wipe under the engine oil cap if anything black or milk chocolate color walk away. GL

ohh and Oil cooler is a must.

I’m tuned and sitting at 225,000 miles with the timing advanced, just intake and exhaust modded along with upgraded clutch and flywheel and stiffer transmission and diff mounts but no issues and compression is still at 210+ on all cylinders and passed leak Down testing

You have to drive it for sure. Nissan's stuff is generally reliable above 100k but these cars are like the WRX...owned by people who like to beat on them pretty hard. I would avoid one of these above 100k as a general rule to be honest.
