Hi guys!

First post!! I am torn between a 2003 Nismo and 2003 touring 350z. The touring just had a clutch swap but the Nismo one has the original clutch with 108k miles. When will that baby start to fail?

thanx

There is no 03 350z Nismo.

 

It probably has a nismo intake and some nismo stickers on it

 

Best first post ever?

 

On a serious note on the thread title. At what miles have real Nismo owners replaced there clutch, and what was it replaced with?

I'm at 35k and it holds strong. No strange noises; no grinding transmission wise.

 

I'm at 52k and having some issues. A lot of rattle noise and I grind when down shifting from 6th to 5th.

 

I replaced mine because the flywheel failed on mine... with all the track day the clutch had still another 50K miles to go.. (I'm at 48ish right now).
the dual mass flywheel is a different story.

 

Nissan down here was charging me 2800 for a oem new clutch etc , something to consider when you weight ur options

 

Haha, this JUST started happening to me, but my tranny only has 28K on it! Thank you warranty! Brand new one on it's way from Japan

 

What did they say the problem was? My dealer is giving me the runaround. I believe the regular tranny warranty is to 60k but I purchased the top extended warranty, so I'm good. Problem is my dealer is trying to tell me nothing is wrong.

 

I assume it's the syncros going out. They didn't say what was wrong, as Nissan doesn't seem to care - at least at the dealership level. If there is something wrong with a transmission under warranty, they simply replace it with a new one as apposed to tearing it apart and replacing what broke. Now this is probably different for non-warranty work, but I have never been in that situation. I've heard throughout the forums that the 5th gear syncro is one of the first to go out.

So the tech drove it, felt the grind, and said, "That's not right, let's order you a new transmission."

Oh, also, it only grinds when the car is cold or warm and at any speed. When the car is hot, there is no grinding. I parked the car at the dealership service lot overnight before the inspection so the tech could feel/hear it at its worst.

 

Looks like I am gonna have to head back to the dealer!

 

Clutch life depends on a lot of things:
Whether you ride the clutch at stop lights
Whether you keep the clutch disengaged at stop lights (generally hard on the throw-out bearing)
Hard launches
Whether or not you rev-match/double clutch your down shifts
Hard shifting
etc.

The more one "uses" the clutch, the more wear and tear, the shorter the life span. There may be some users who will put 100K plus miles on stock, original clutches without a problem.

There may be some users that are already on clutch number 2 at 20K miles, it all depends.

As to the grinding from 6th-5th: the 5th gear synchros are probably worn. This may be an inherent design flaw in the Nissan transmission, I don't know, but it could also result from repeated 6th to 5th down shifts w/o rev matching. 6th to 5th is theoretically a oft-used shift on the highway, especially at legal speeds. It has been my experience that the car really doesn't want to accelerate in top gear on the highway at 60ish mph, but if you down shift to 5th, problem solved. If you do a significant amount of highway driving, and find yourself shifting between 6th and 5th often, try rev-matching/double-clutching your down shifts. It will save a lot of wear-and-tear on the clutch and gearbox and it sounds cool, too.

 

I know this is a nismo section but i have a 03 base with 141k miles and im on the stock clutch. it starting to give me a little slippage now so im going with the JWT or nismo clutch. i get a HUGE discount on all nismo parts so ya. clutches are all how u drive them
