I have an 06 z and I also just got done shifting from 3rd to 2nd, my whole car got sideways I thought I was screwed, luckily as soon as i stepped on the clutch it straightened out and everything sounds ok... But it sux *** because you feel like you have done some damage.

Thats the problem with short shifters sometimes 
It was an honest mistake that could happen to anyone. I am sure that your Z is fine since it was not running @ 8k rpm for long.

I've done a 3rd to 2nd one time, but it wasn't that bad.

In the BMW community they call this "money shifting" because that shift just cost a lot of money. It is a common problem with the 1995-1999 (E36) M3. When I had an M3 I had to pay particular attention to this. With my 350z I know it can happen, but it is not as easy to do as it was in my M3.
To the OP, I'm glad to hear that your engine is still running fine.

The rpm limiter will cut the power down after red line to help save the engine, but it has to be hard on everything, and could happen too late. Before I got totally comfortable with this shifter I admit I did the same thing. Luckily I escaped with nothing but a red face. Really embarassing on a first date with a woman that knows her car stuff. Strong lesson learned.

No rev-limiter is going to stop the mechanical load placed on the motor from this scenario. You could completely kill both fuel and spark to the motor and the RPMs will still skyrocket.

I too have done this. It was troublesome at first, especially since I drive and 18 speed and have been driving commercially for 30 yrs. Just gotta be real careful. The two Porsche's I test drove,Carrera 03 and a 07 short shifter Cayman have much better transmissions as well as clutches. First time out I was really testing the gears without a mishap. Hell I can barely do that in the Z after 6 months.

shifting
The 350Z is not an easy car to "break in" shifting. I have owned several stick shifts over the years - including the 300ZX and this one has been far the most difficult to "break in". It took me 3000 miles of short driving to really get comfortable with it. I was often dying at intersection stops, etc. Now, at 30,000 miles I love the car and find it very easy and do lots of downshifting during short drives or coming off the expressways.

I did the same thing as the OP with 500 miles on it. Dang near broke into tears. I now have 40,000 miles on the car, but was wondering how I would know if everything was fine.
