Z1 CSC Elimination kit review
 

So I haven't been able to find any review on Z1's CSC Elimination kit. Maybe theres one in the CSC failure thread but with so many posts, I figured it would be better to start a new thread.

So I had my CSC fail for the second time. The first time, I just had the dealership replace it and it was covered under warranty. I have moved since then, now I am over 45 minutes from the closest Nissan dealership and since these seems to happen to me every 20k miles, I decided to go with the CSC Elimination kit.

I bought everything through Z1, I bought a mid weight flywheel and standard full face clutch combo and added the CSC elimination kit upgrade. This kit came with everything I needed, including a SS clutch line, except fluid. I also bought a new OEM master cylinder as well.

I took my car to a local transmission shop to have them install the kit. Their comments after the kit was installed was that they are unsure how well the new Howe Racing slave cylinder will hold up, but the rest of the kit, specifically the clutch fork, seems really stout and built to last. As for the new slave cylinder, I am confident that if it were likely to fail, Z1 wouldn't have choose that part. And in the off chance it does fail, it will be easy and cheap to replace or rebuild. Overall, the transmission shop, Gateway Transmission in Oak Harbor, did the whole thing for about $1400, which includes taxes. Something else they told me was that my stock flywheel was about shot too, so this CSC failure was good timing in that respect.

After this kit was installed, I immediately noticed a difference in clutch feel. The clutch is heavier than stock. The clutch is not too grabby though, even though it engages and disengages very low on the clutch pedal. This will take some getting use to, shouldn't take too long to do so.

As for the mid weight flywheel, it is not a huge difference in engine response, but it is noticeable and I haven't notice any sacrifice when compared to the stock flywheel. I don't really hear any chatter. For me, it is a little harder shifting both smooth and quickly, but that could easily be the new heaviness in the clutch or a the clutch being slightly more grabby than stock, time will tell.

Overall I am happy with this kit, and if I never have to deal with a blown CSC again it will definitely be worth the time and money this kit cost me. I am more confident in the durability of this kit over the stock CSC. Even if I have to replace the Howe Racing CSC, its a $60 part and is completely accessible, which is much more than can be said about the OEM parts. I hope someone finds this post helpful and if you have any questions, feel free to ask.

That was just for labor? That's more than double I had to pay, but then again I assume the HD CSC route is more straightforward vs. the elimination kit which ideally would have more careful review.

Yeah that's just labor. I don't think you have to drop the transmission to install a HD CSC. You do with the elimination kit. You also have to measure the depth of the clutch and flywheel to set the fork pivot in the right place. It's a pretty involved install

You drop the trans for any type of work related to the CSC system, unless it's a line to the CSC or the master.

I've been running my Z1 CSCEK for about 2 years and 35K miles. My first cylinder failed after less than a year. I purchased a new one and Z1 refunded me after I sent the old one back. No issues since :driving:

I'm very glad I never again have to drop the transmission for clutch hydraulic issues :tup:

Thats good to hear, it seems like it would be very easy to get too. Im assuming that you just replace it, then bleed the line?

Yup. IIRC the replacement took ~20 min plus bleeding. Very easy. I keep an extra cylinder on hand so I don't have down time if something else happens.

For the record, I went through 4 different slave cylinders in about 5 years and 50K miles with this kit. Finally switched over to the ZSpeed CMAK. No more adjustments needed :woot:

ZSpeed CMak is going into my build as well!

I have the Z1 elimination kit as well. So far it's been doing it's job. I have not adjusted it since I've gotten it, it's been like, what? Three years since I installed it? I have no idea how to even adjust the thing to begin with so there's that haha.

Glad you are enjoying it. Zspeed has a self adjusting elimination kit which many prefer. Both make good CSC eliminations kits no doubt.
