The numbers that Acura quoted were retail sales in the United States because they have no connection with manufactoring to find out how many were produced. So, if Realtime went down to a dealer and purchased two Type Rs, then they are included in the 318. I do not know the story behind them, but since they received numbers 0001 and 0002, I doubt they found those at a dealership. So, they are most likely not included in the 318.

On a side note, when was Realtimes first race with the ITR? I am pretty sure it was in 1997. If they got them when everybody else picked up their ITRs, I do not think they would have had time to prep them and get them on the track that quickly.
