As I have no idea what a V3 Type R and RA is I'll just have to accept it at face value. Is it an STi Subaru Impreza? Why not just call it that? It seems to be fashionable to refer to everything via the manufacturers codes to make everything sound impressive...
I know that the STi we worked on in 1997 (I think it was) that we got to 700hp for Pikes Peak (we didn't do all the work as we're not modern car or Subaru specialists, although we do specialise in the engine that Subaru copied) didn't have any of this computer nonsense.
Okay, a slight lie, as we fitted a Motec ECU and datalogging system, but that was recording everything and giving us a fancy digital dash display.
