U.S. manuals suggest keeping the revs below 4200 rpms for 2k and no full throttle applications. Drive at low revs until the oil warms to a min. of 180 degrees F.
I would add, that I'd vary engine speed over the break-in as well. After a spirited effort, let her catch a lot of cooling air, driving moderately. (the hot/cool cycling adds to a tight seal; imo)
Lastlty, many others suggest higher rpm limits. Not to discredit anyone, but how do these people come to these arbitrary numbers? Many validate their opinions because they haven't had any engine related issues, etc... This data is unreliable (IMO) because many do not own their cars long enough to realize some of the likely ramifications of an improperly broke-in engine.
You can't go wrong with the manual. Your car will be every bit as fast and may just be a little more reliable over the long haul.
