How many miles are on the original clutch/flywheel?

That link you posted includes a new flywheel as well. While the OEM dual mass flywheel cannot be resurfaced, if it is in pretty good shape, then you do not need to replace it with a single mass "stage 2" (whatever that means) flywheel unless you're looking for the concrete mixer sound at idle/low rpms.

Since you're staying stock, I would go with this option from Nissan Value Advantage: https://www.z1motorsports.com/clutch...d9bbcca3c35312

 

I was running an ebay clutch on my setup with 335tq and it held up until I increased my boost further, except I was running the 14lb ebay flywheel. I just put a 6 puck ebay clutch in it and it actually feels much smoother than the "stage 1-2" which is really just an oem disk if you look at the part number
This is the flywheel I'm running, except I think it was actually 13.8lbs not 14.5

car is not an 07 though

 

Yes, it is a 2007 but it is a version called VQ35DE Rev Up.

I was wondering if this clutch kit is compatible with my car?

https://www.z1motorsports.com/z1-pro...t-p-15507.html

 

negative sir... 07s have the hr motor with dual intakes like below... unless they did the revup for non US cars, which i doubt



but yes, that clutch will work

 

My car has the red line revs at 7000, a normal Z with DE engine has the red line revs at 6800. I am from Costa Rica and the car was bought here.

What confuses me is about which parts to buy, because when I select Z 07' on the websites, it shows me parts for HR, but mine is a 07 DE. So by logic, I would have to buy parts for DE?

 

that is why I said they might have done something different for non US models. for you i would look at 06 items for motor and trans

but now you have me curious, on the trans do you have the external slave with clutch fork coming out of the housing? the hr 07-09 here in the states have the internal slave

 

This is the original clutch kit on my Z, it is giving me problems and I have to replace it. Which one would you recommend me to buy?

 

i cant say without knowing if you have the external or internal slave cylinder

 

It is external

 

good deal....iideadeye has run ebay, z1 would be fine

 

I'm a little short of budget because it wasn't something I had in mind to change soon. Do you think that for a daily car use this clutch will work well for me?

i am sure it will be fine

 

Since you have the external slave, if you're shopping vendors in the US, it would appear you should be looking at compatible clutches for 03-06.

But, if you're keeping the OEM flywheel and since you're on a budget, just get the clutch and save $100, No need to get the lighter flywheel.

Here are some ebay options:

Also, what problems were you having that has led to the conclusion of replacement?

 

The car lost power, the gears did not enter correctly, the clutch pedal was stuck to the bottom on 1 occasion. And when we opened the part we saw that it was totally worn out.

I don't really know much about technical mechanic, but my mechanic recommended me to change the whole clutch kit, including the flywheel.

The best option I have found is this: https://www.ebay.com/itm/164355176269

Another option would be to buy a DE clutch kit from Z1 Performance, but at triple the price. I guess it is better quality. But I only use my car for daily driving, without stressing it too much. I really just want to get it running again since it was something I wasn't planning on changing at least in the short term.

 

It seems like smaller markets got remaining DE/DE RevUp units in later production years … There was a 07/08 model that had the single intake in New Zealand / Austrailia?? Here, a few years back…

 

its very possible.

 

Gotcha. The clutch pedal being stuck to the floor is a pretty common issue and that may not be the sign of a bad clutch/flywheel, but a failure in the hydraulic system.

But yes, that clutch flywheel combo should be fine, I guess. I don't typically buy ebay parts for vital components, but I get that you're on a budget.

I hope it works out!
