Nope, thats Gavin Strongmans old car,
it is now owned by vince harlor (sydney), he also has the RB25DET (No399) 240z that took out the Nats in 2005.
He had both cars there on the weekend.
The RB car had an extensive write up in Fast Fours July 2004.
Think you will find that the 260z (orange strip) would have been quicker if Gavin was still driving it, Vince I think is more interested in having a good time rather than ultimate speed.
