Default Do I need a new flywheel?

Hello, I just picked up a 350Z with a rod knock, I have never driven a 350z, including this one. It has 150k miles on it. While I had the engine out, I noticed the clutch is worn to the wear lines on the outer edge. So I decided since I am keeping the car I will replace the clutch. Then I noticed the dual mass flywheel has some play, I am trying to figure out if it's within specs, or if I should replace it. Here is a video of the play in the flywheel.

I can't view the video you posted, but If I were you I would replace the flywheel. It's easier to do it now with the motor already out. I had my stock flywheel go bad at around 100k miles, there was so much play in the flywheel that it caused the entire car to shake/vibrate when driving over 50mph.

If that was mine, I would do:

- CSC elimination kit
- New single mass flywheel (w replaceable friction plate) and new clutch
- HD Wilwood Master cylinder
- RBF 600 Motul
- (optional) aluminum driveshaft
- (optional) RJM clutch pedal upgrade

I would do everything at one tranny drop so I won't have to worry about it for the lifetime of the car depending on your driving habit. GL

Why do you recommend single mass flywheel over dual mass? Single mass is cheaper... seems like the dual mass would have to be better somehow. I had a Mercedes SLK 320 it had a dual mass flywheel and it shifted pretty smooth especially from first gear.

Read post #2, his stock dual mass went bad at 100k. Single mass are more durable and reliable, (lightweight) if you aim for longevity. The only catch are flywheel chatter/noise which I don't mind but it is not for everyone.

Read stickies, browse the forums about why lots of owners yield more to single mass flywheel.

How's that an improvement over the factory carbon fiber shaft?

Because I have a g35 and ours don't come cf from factory and aluminum is what I can afford.

Rebuildable Single Mass FW is nice. For me the torsional vibration or "chatter" in the gearbox caused by running a single mass is a bit annoying though. I did not experience any issues with shifting using the clutch/FW combo I chose (SpecialtyZ FW with their Sport Street clutch). The RJM clutch pedal is a must in my opinion. No need for the bigger master cylinder/slave cylinder unless you're running a race spec clutch setup. The CSC delete option is great if you have an 07-08 350Z with the HR engine. If you have an 03-05 350Z, you should get the cast clutch fork found later in 2005.5 through 2006 350Zs. The stamped steel forks in previous years were prone to failure along with the longer fork pivot ball found in the 03 Zs.

Good Luck with the Z!

Can't see video/haven't read other posts, but my dual mass flywheel in my Audi (180k miles) would move significantly back and forth. I chose not to replace when I replaced the clutch(no springs in oem clutch plate) and it's fine. I get very minor clutch chatter, but other than that it's fine

if you are doing the engine + the clutch is that bad, I would def do the flywheel and while you are at it check the differential too.
