I just contacted my dealership about getting a NISMO flywheel installed in my 05 6MT coupe. They said they have to check into whether or not installing it will affect my drivetrain warranty. I find it surprising that installing a Nissan part that is intended for the VQ35 powertrain would void a warranty. They're going to call me back with an answer, but does anyone here know anything about this?
It shouldn't because I read in another thread (it might have been on G35Driver though ) that someone had a S/C installed by their dealer and the dealer said that it wouldn't affect the warranty. That's a S/C! I wouldn't think a clutch would be any bigger of a deal than that but then again every dealer is different so who knows!
Thanks, that's what I thought too! However, I just heard back from the dealership and they said that they wouldn't install the NISMO flywheel because if something goes wrong with the car as a result, it's on them. They also said that installing it would void the drivetrain warranty!
I find it very surprising that installing a Nissan manufactured part in a Nissan vehicle would void the car's warranty. I also find it surprising that an Infiniti dealership wouldn't be willing to install a Nissan part! You'd think that they could get alot more business selling and installing such parts, wouldn't you?
There are two types of NISMO parts, the S-Tune and the R-Tune. The S-Tune is intended for the "Street" while the R-Tune is intended for the "Race" applications (i.e 1/4 mile strip or race track).
The S-Tune will not void your warranty, but the same cannot be said for the R-Tune. I think that the way Nissan looks at it, if you are sticking those parts on your car you are going to race it and that goes beyond the intent of the warranty of the car since it's not a purpose built race car.

OK, GZire, I can understand that. But what category do the NISMO clutch and flywheel fall into? How is it determined if it's an S-tune or R-tune part. Everything I've read about the clutch and flywheel indicates that it's a street-purpose part.
Thanks so much for the help, GZire! I'll check out the list to see where the NISMO clutch and flywheel fall.
I can't believe that I need to do this. If it turns out that I can't upgrade the clutch and flywheel in this car due to warranty issues, I'm gonna have to sell it. I hate the rev characteristics that it currently has when you spin it up past 4000 RPM. It didn't seem bad to me when I was babying it in order to break it in, but now that I've really given it a decent rev and see how it behaves, I don't like it one bit. I prefer a much faster revving powertrain.
I don't like how this car launches, either. Maybe it's me, but I've been finding it difficult to get the clutch to grab well when starting out in 1st, even under normal, mild driving conditions. I thought at first that I'd just have to get used to it, but I just can't seem to find the right technique and I'm starting to think it might not be me.
Well, that explains it. I just checked the list and it turns out that the NISMO clutch and flywheel are R-tune parts. Not only do the parts have no warranty, installing them also voids the warranty on your drivetrain according to the Nissan web site.
From the way it looks, any NISMO part that is a simple bold on (i.e. wheels, body parts, cat-back exhaust, etc.) is considered S-tune while mods that require taking any part of the drivetrain or engine apart to install are R-tune. In other words, they assume you can bolt some crap on and not mess anything up, but they're not going to trust anyone (not even the dealerships) to take any mechanical components apart to install a part and still cover it under warranty. I guess they also figure if you're hardcore enough to want to take your new car's engine apart to make it faster, then you're probably going to be putting it through some abuse that they would rather not cover under warranty.
I guess I'm stuck with the stock setup unless I decide to sell it or take the plunge and void my warranty. Pretty crappy clutch design for a near $40K sport coupe.
this is all very good info!!
thanks to both of you!
there still has to be someway around it tho.... they don't make an S-tune clutch? plus as far as someone taking it apart (even dealerships) they need to when installing a new OEM one

No S-tune clutch or flywheel listed on the Nissan web site. I'm not going to risk a 7-year 60,000 mile drivetrain warranty on the R-tune one.
As far as the dealership taking the clutch apart, apparently they only want to do that if it has to be done (i.e. the old clutch is bad) and then only to replace it with another OEM clutch so as not to risk damage to any other drivetrain components.
I'll just have to try to get used to the OEM clutch and, if I can't , sell the car and buy the BMW 3-series coupe when it comes out in 06. Don't want to have to do that, though. I like the G Coupe, I just don't like how the engine behaves at high revs due to the heavy flywheel. And let's face it, part of the reason we buy cars like this is to get the revs up and go!
If anyone knows of a light-weight flywheel for the VQ35 platform that won't void my warranty, please post back. Thanks.
you don't have to use their spark plugs or oil... or tons of other stuff... that's BS
That's a good point, actually. The clutch, like tires, spark plugs, belts, etc., is a wearable part. I should be able to use any clutch I want with no effect on the warranty.

Damn, now you've made me mad!!!
i know but it's very true. i doubt that in a court of law -- their side would hold up.

This is the same way it was for my old Toyota. I don't think you have to use their equipment but you do have use the same specs. I believe a lightened flywheel can have effects on other aspects of the car which is why it negates part of your warranty.

That's true, as well. I suppose if I found some aftermarket 30 lb. flywheel out there maybe I could use it, but that wouldn't solve my issue of being annoyed with the heavy flywheel and it's effects on rev response.
I'm not sure what ill effects would come from using a lighter flywheel. Maybe the drive train just isn't engineered to withstand the additional stress of revving up and down quicker. Who knows.
