Clutch pedal sticking and burning complaints come here

I searched and did not see any solution to all the clutch complaints.
I know what is causing this problem because as soon as I drove my car the first time I knew there had to be a clutch restrictor in place.
Before saying anything I wanted to get my hands on one for inspection/modification from Chad but he has not answered me after a month.

Both our cars and the 350Z have an inline "clutch orifice" that is restricting the the flow to prevent dropping the clutch and breaking something.
If you know how to drive a manual these things are the most annoying thing because the ruin clutch feel in addition to the added protection.
Everyone who has replaced the clutch pressure plate has gotten releif because of the higher spring rate of the new pressure plate.

The orifice is located right in the left fenderwell and can be seen through the holes in the cover (at least on my 06 coupe).
Hopefully soon I will get an opportunity to take it off and see how it is designed. If it is simply an orifice then it will need to be drilled out to remove the restricition. Normally they are placed at the slave cylinder and are spring loaded plastic orifices. The one on the G appears to be a brass body so I am thinking it is just an orifice as they call it.

This mod will fix pedal feel so you will more easily be able to engage the clutch on launch and while shifting.
This mod I expect to reduce the clutch pedal "stick" which is actually a lack of fluid returning back to the master cylinder.

The Evo is notorious for burning the clutch and this is the real reason why there were so many people with that "burning" smell. I removed my restrictor on the Evo almost immediately and the feel was night and day and the only time I ever burned my clutch was when I had huge cams in the car and it barely idled and I was trying to carefully drive it up onto the Mustang Dyno.

It's happened to me only once. But that was in extreme heat. From what I've gathered over on my350z is appears to be an issue with boiling clutch fluid.

i know what ur talking about, but most of the people i see driving the G honestly do not know how to drive stick, thus, this protects them.

i learned on an old bmw 2002 and i hate the G's clutch

Angry clutch got stuck

Yah! That's happened to me a couple of times already where the clutch got stuck and I had to pop it back up. I brought it to the dealer and they told me that nothing was wrong with it (at that time it didn't do it), and that it wasn't out of normal for these problematic infiniti and nissan transmissions.

I noticed it most when the car was new. Now I only get that smell after doing a big honking burnout (rev the car up to about 5 grand and dump the clutch). Screw it, its worth it. When it wears out, I'll change it, no biggie. Just drive the damn thing and quit worrying about the small stuff.

So that's what is going on!
I have driven manuals for too many years to be as bad as the G makes me appear. I thought it was some kind of goofy design that didn't allow the clutch to engage smoothly. The clutch engagement is not linear. BUT ONLY SOMETIMES. Which is a pain in the a$$. I drive my son's GTI and I shift butter smooth. I get into the G and depending on things I don't understand I will shift like a noob. Very frustrating. If this is the fix then HALLELUJAH!

I drilled mine up to 7/64. It is not much of an orifice to start so the impact is not what I was hoping for. My car is new so in time the pressure plate may get stiffer an will improve the feel more.

I do notice a difference, it's not what I had hoped.

After driving for a couple days like this I feel that it improved the engagement of the clutch. Hard to explain but I don't find myself missing the clutch engagement and getting that buck that I used to because it seemed like you are always guessing where the clutch is going to engage.
Pedal feel is really no different.

If you look in your driver's front fenderwell at the rear side you will see a couple holes in the shield. There is a brass block right behind it that you can see. You have to remove the inner fenderwell and remove the block in order to drill it out. I managed to do the job without bleeding the clutch.

I was hoping to get a price on these from Chad at InfinitiSpecialists but he never answered me. I could have drilled out a bunch of them for anyone that wanted to try it.
