Just by looking at the numbers I think if you plan on going forced induction i.e. Nitrous, Supercharger, or Turbo the Base RSX is a much better platform. It has a lot lower compression ration at 9.8 and also is geared taller. With the lower compression ratio it would probably be able to run 9-11 lbs of boost without rebuilding the block. The only problem may be the ECU but this won't be evident unitl later. If you just plan on putting bolt ons such as Intake, Exhaust, Pulleys and a header (if ever developed) then the Type S is going to be a better candidate. Times in the low 14's or maybe high 13's should be capable if tuned correctly. Just my thoughts.
