Possible Nissan OEM clutch system issue - Everyone Read

RCZ

Well, the issue isnt in the parts. In fact there are a lot of happy people with the same clutch in the 370z. The problem is that the grabbiness of that clutch exacerbates the issue much more than the stock setup does. I no longer have the Southbend installed, replaced it with a ClutchMasters Stage 2 and all of my big problems are essentially gone. Why? Because the Clutchmasters is a much more forgiving clutch so it allows that drag to go by unnoticed, just like the stock clutch does. I would bet the farm on the fact that a whole lot of people have clutch drag and don't know it because the stock clutch hides it.

Compared to my '06 STI, my car's transmission is junk. There was nothing more satisfying than revmatching and going through the gears in that car (specially after kartboy bushings). In this one, I dread having to shift. I am not getting any grinding or clanking. The only problem I have is the one caused by the clutch drag; resistance to going into gears smoothly.

And whats with the crazy bogging when you hit the gas hard at low rpm. It is clearly being held back electronically. Whether its supposed to or not, it sucks for drivability. Sometimes I want to merge into traffic quickly and the car just makes noise and goes nowhere until a little bit higher in the revs. I'm not expecting full torque at 1000rpm, this is different. This has been reported many many times and there are a ton of threads about it AND the car did it before the SC..so I know its not that either.

Why Nissan!

Well that sucks. I thought the stock STI trans was... OK. Mine had about everything Group N/Kartboy/Turn In Concepts you could get as far as driveline stiffening on it and I still didn't think it was that great. I didn't think it could hold a candle to my S2000, but that is no surprise, not many things can compare to that trans.

But it's not like my HR Z felt like a hunk of crap compared to the S2K (other than the clanking) and the 370Z feels better than the HRZ, so, like I said, I think your transmission has a problem.

I don't have that problem, either, thankfully.

I guess I'm just rubbing it in...

Nah, I just know these problems don't happen with every Nissan, and complaining about it on forums isn't going to do anything. Complaining to dealers and complaining to NIssan is what would solve the problem. Loss of power is a serious issue. If you can reproduce it regularly, take it for service. If they can't fix it, LEMON LAW THE DAMN THING. Nissan will take notice when it starts costing them money...
