New clutch time
 

Most of you know my csc failed at Zdayz on the dragon so it's upgrade time while it's apart.

I'm looking at 2 kits from Zspeed. Seems the only difference is the flywheel. I don't know enough metallurgy to know which one's better and I wouldn't think the 1lb difference would matter much. Is the SBC better or can I toss that $100 in a jar for a rjm pedal?

EDIT:

Z1 poly trans mount? any other options?

Nismo pilot bearing? any reason to not spend that $14
many reasons to avoid it

Anything else while it's out? It's at 63k. Going to inspect the rear main seal but didn't plan on replacing it unless it shows signs of seepage.

What did I miss?

You miss yours,Spoiler’s & Rusty’s old ladies breaking bad on the dance floor; also your cold ones wrapped up in a hoodie :happydance:

Clean all hardware up with a rethreader kit & just take your time...you mentioned a Torrington style pilot bearing vs. the bronze bushing,don’t forget to drain gear oil before installing cmak...watched someone do it :wtf2:

What size thread chaser is that?

Thanks for the reminder on the bearing, I might have had a beer since then :roflpuke2:

The fluid is coming out as soon as it's off the ground. I'm sure it needs changed after the trip home:driving:

Forgot the mount to. Was going to get a Z1 poly unless someone has a better option.

Had good results with the Z1 poly. Solid mount NVH will knock some plaque loose, stroke you out.

Stick with the Bronze pilot bushings. The Torrington styles just don't last and are a complete pain in the butt to get back out. Ask me how I know. You will need new flywheel bolts, they are Torque to Yield bolts. One use only.

Can’t remember size’s; as this was done September 18’
I brought my kit & they’re not badly priced & clean up bolts & hoes very well :wtf2:
Didn’t know the flywheel bolts were torque to yield (as Spooler mentioned) as the book had given a value on them & that’s what we used.
Also we used a flywheel turning tool to hold everything steady while torquing flywheel bolts....it rest nicely on the right side subframe mount without damaging handle of tool & is out the way of your torquing :ugh2:

get the south bend billet steel flywheel, almost no noise and it comes with bolts if i remember correctly

So you are dead set on Joe’s Z Speed Stage 3 clutch? If you are planing on more track days in your future get the RJM petal. The weight difference between his forge steel and billet steel flywheel you will never notice. If you do more street duty with your Z get the forge steel flywheel and if you do more track duty with your Z get the billet steel flywheel you can’t go wrong with either. You can get any replacement brand polyurethane transmission mount just don’t get the solid transmission mount unless your Z is a deadicated track car. Honestly I never once seen a rear main seal leak on a Nissan a specially our Z’s leak. Unless you see your rear main seal leaking or abnormally wet with oil don’t replace your rear main seal and if you do replace it use the replacement Genuine Nissan rear main seal. +1 on the bronze pilot bearing they are very durable and last. Make sure you replace your flywheel bolts as they can only be used once and don’t forget to replace your pressure plate bolts they are important.

Not dead set on anything other than the CMAK. I was shopping Zspeed since their kits have about everything I need and free shipping.

It sees more street than track. I'm looking in to more hpde and I take it 1/2 mile drag/roll racing once a year. 30-50 2 step launches over 2 days. I was shopping the stage 3s knowing the ultra light flywheel will not launch as well but will be better on a road coarse and in the mountains. It will hold way more power than I'll make anytime soon but I liked having the overhead.

The rjm pedal is in my sights but at the bottom of the list for now.

I went went with the JWT Clutch and Iron flywheel combo, the JWT clutch can handle up to 600 horsepower and a lot of people said they are great. Plus for the price it's really great. https://conceptzperformance.com/jim-...ktb_p_2423.php

And the Heavy Duty CSC by Z Speed instead of the CMAK because people have come across problems with the CMAK https://conceptzperformance.com/z-sp...006_p_4593.php

Keep in mind, if you go from the stock dual mass flywheel to ANYTHING ELSE, the transmission chatter will increase regardless if they are advertised as "quiet". Just a warning because it looks like the clutch kit your looking at, that flywheel is 19lbs vs the stock 32lbs which will increase the noise if you care.

I went with the Z1 Clutch/Flywheel kit along with a ZSpeed HD-CSC. Have been very happy with the setup and haven't had any issues even with the TT torque increase.

I think if I did it all over again, I would have skipped the flywheel upgrade to keep the chatter down as my car doesn't see any track time.

while you're doing the clutch and slave fix, get a lightweight flywheel and the RJM clutch pedal

I don't think he wants the extra noise

It can sound like bolts in a dryer for all I care. Both kits I listed have sub 20lb flywheels.
