Exactly what I was getting at. That motor was designed for performance. When Honda was designing the S2000, it was originally intended to have 215-220hp and weigh xxxx lbs. When they got the road-version ready, it weighed about 150-200 lbs more than they thought it was going to. They had a target power-to-weight ration in mind, so they simply upped the anti and did whatever they could to get more out of the engine: i.e. less conservative tune, higher rev-limit, etc. Your average non-turbo car, (i.e. the ESI mentioned above) is not going to have such an aggressive tune on it from the factory, and will not care as much about higher octane gas.
On the flip side of this whole discussion, I have a friend that used to have a Volvo 850R (turbo). He always put 87 octane in the tank because it was cheaper & he claimed he didn't notice any difference--of course, the car was un-modified, and it was an automatic (but nice!).
Side note: Does the s2000 require premium (i.e. per manufacturer's spec)?
