Secret source..... that mean all the stuffs he/she said is unofficial, that mean the
"Secret Source" could be the editor himself....
A (new)530hp engine.....?? They have one already on the GT-R, why waste money on making a new one, port the current 530hp GT-R onto the new/future Z platform, use that funding to make a new engine for the GT-R, done deal.
In fact, they port the GT-R engine in a Juke and it works fine, why can't/wouldn't they do that on the Z with a new chassis??
Anyway, anything with unknown source, discreet, whatever secret...... I look at it as
just for laugh or
