I think a 335 whp turbo Miata would put a major hurting on an FP S2000. If there's an S2000 in the competition it's going to need forced induction to keep up. That, and since this is a competition among tuner cars a factory-fresh unmodified car wouldn't be one of the entrants.

As far as any sort of Silvia, thus far all of the cars in the last couple years have been done by tuners who sell to customers in this country. The Signal car is a drag racer and wouldn't be very well-suited to this test which is mainly a road course with a top speed run.
