Funnily enough I've just managed to get the paint code off Ben Ellis the previous owner (and zoom editor). It is actually a toyota colour 'TAU 3N9', I think tau might stand for toyota australia?
There are some scans of the original article at www.blkmgk.com, click pics and then 1jz in 240z. It isn't my site, so I thanks the owner and hope he doesn't mind me sending people over!
