that car sounds sick!! i highly doubt that nissan is going to leave much room for improvement. however the last skyline eninge was "the" engine for tuner to get ungodly speed and hp. so i am sure the power, even though it will be high, will have room for imporvements. but to run with a 911 turbo is a good starting point and if that isn't a full production car yet, i would say that the production car will eat a 911. if its only a few tenth (or so) behind now.
