A few questions for a new Nismo

Zuppy51

I for one never listen to a sales person for any technical advice. As there as so many models and technicalities they tend to use generic broad strokes to communicate things to the owner.

Congrats on the new purchase! Check your springs for shipping spacers and check the air pressure in your tires....

For future reference, your owners manual spells out break in quite clearly. If you have any sort of large scale mechanical failure, they can diagnose your driving habits through you're ecu and can void your warranty. If they found out you abused the break in, and had a problem it can be costly.
Ask me how I know.... I did this to my S2000, I blew something in the head over revving it with 1800 miles on it, at a track day. Needless to say it cost me plenty.

Owners Manual:
Page 5-22:
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and
ensure the future reliability and economy
of your new vehicle.
Failure to follow these recommendations
may result in shortened engine
life and reduced engine performance.
. Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
. Do not accelerate at full throttle in any gear.
. Avoid quick starts.
. Avoid hard braking as much as possible.
