If I remember correctly:
The Turbo S was a special version of the Turbo 3.3 that was meant to celebrate Porsche winning the IMSA supercar championship. It had uprated components like brakes, different cams, and ran higher boost than the standard car. I believe that it had 381HP as oppossed to the standard Turbo's 315. It was kind of track oriented though, power was tilted even more towards the top of the tach than the standard car. For everyday driving and speed I think the 94' Turbo 3.6 would be better. What it loses in ultimate HP it makes up in more and more evenly spread torque. Car and Driver tested one of these Turbo S, you could maybe look up the article in the library. As for value, I think it would be higher than the standard turbo and will maintain that value simply by its exclusivity.
