the noise you are describing is from the transmission. It is there stock, but no where near as loud as once you replace the stock flywheel.

it can be very loud at times, and is generally loud at idle, and louder when loading the trans/engine below 3000rpm. it is usually much quieter while the trans fluid is still cold. idling on a hot day in a drive through, the noise is loud as hell and the drivethru window person will think your car is totally busted.

its completely typical of this transmission and does not mean any failure is impending. 350z's did it also (same trans, different case), and go on doing it for years and years and years with no issues. My 350z trans was extremely loud and lasted like that for 9 years before my friend who bought it finally had to replace the gearset due to the 3rd gear break that eventually happens at high power. Even with the brand new gearset in there that he took out of a HR trans and put in his DE trans case, it still makes the noise.

When sitting at idle next to a wall at full temp, when its being LOUD as hell, you can confirm it is the transmission by simply pressing in the clutch, and noting how the sound completely goes away. Unfortunately those of us with twin or triple clutches, get to exchange that sound for the loud chatter of a multidisk clutch any time the peddle is down.

No worries!
