Not that you have to break it in properly, but the owner's manual says to not go above 4k RPM until you hit 1200 miles.

I was once at the drag strip with my old supercharged 350Z and accidentally misshifted and went to 2nd while at redline in 3rd, instead of 4th. The tach went to the 6 oclock position on the gauge for a split second before I got the clutch in. Fortunately, no damage, so the original poster should be fine.

set your shift light to 7k just to be safe

Everyone misshifted at some point. I myself misshifted few weeks back revving the engine to 7500+ RPM. As long as you quickly fix the mistake (i.e. shift to higher gear or neutral) you should be fine.

Reving =/= Red-lining

EDIT:

I took my Z out tonight for a little drive to push it past 5k RPM for the first time ever. I almost hit 6k RPM in 3rd gear before shifting to 4th, and it definitely didn't feel smooth RPM'ing that high. Obviously the cars I've driven before weren't sports cars, but the difference between RPM'ing at 3k and 5k in my Scion tC was the sound...the car didn't feel any different. My 6k RPM felt "abrasive" on the throttle and didn't sound as pretty as 4k does. Is that normal? Very noob question, I know...first time I've ever gone over 5k RPM in ANY car.

engine harshness at high revs

If anyone is interested, I found the answer to my own question in that thread.

Is something that we have to live with or does it get better with a few thousand miles on the engine? I'm not sure I'll ever get into the 6k range again to avoid this harshness, unless it's absolutely normal and harmless.

I have around 8,500miles on mine. I drive mostly on the backroads and frequently accelerate hard. The harshness everyone is talking about is still there, but is much less than it was @ break-in (2,000 miles). Use a quality synthetic and have fun with the car. These VQ's age well (take a while to really break-in).

An interference engine is one in which if the timing belt breaks, and the valves come fully down, they don't come down far enough to make contact with the piston, thus saving your engine. Typically, an interference engine results in lower compression so its not likely that the Z has it. Again its designed for when the belt / chain breaks not so much for when the valves completely float due to overreving, so it may only be of minimal help in that case. But, if you haven't noticed any rough idle by now you should probably be fine.

I come from a Toyota Celica GT-S (2000) before the Z and many people used to misshift that car all the time due to the tight gearbox and ended up blowing their engines. It got so bad, Toyota actually replaced most of the engines under warranty. Some people were out of luck if they went to a tough dealership to get it fixed.

No noises? no misses? no problemos? Don't worry 'bout it!!

I've engaged the saviour, err, rev limiter a couple of times under load and the engine was not harmed.
