I don't know about a nissan, but the camaros have the same speedlimiter 
if you order the car with the default tires. These tires are H-rated,
and they put in a 108mph speedlimiter for liability reasons. If the
car is ordered with the optional Z-rated tires there's no speedlimiter.

for the Camaro hypertech makes a flash-memory programmer that can remove
the limiter (among other things). Don't know if they make one for a
nissan. Check out their web page at www.hypertech-inc.com
