E-I has a news item on the car:
-It's called the GT-R RC (Racing Competition)
-Figures quoted are 1520kg and 485hp. That's less power than the road car and much too heavy but I guess the engine can make more.
-The picture of the car's rear shows exhaust outlets that - I'm 99% certain - don't belong to a V8.
