Just looked it up and apparently there's no RS models, only a RACE BASE model. . . .
"This is a lightweight edition of the ek9, produced by Honda for the Japanese market. These models are very rare in the UK. This is a proper track car but can also be used on the road as a daily runner. This car also benefits from 5 extra bhp from the normal ek9 so is 190 bhp standard.
To save the weight the car has no abs, aerial, airbags, red recaro interior, electric windows and no sound deadening.
The car has power steering which is very response and gives a lot of control. There is also air conditioning fitted due to the heat in Japan."
It's what I found on this site when searched.
Then the RX model -

Hope this helps.
