If your talking about horse power then the f20c beats all just because it produces about 250hp naturally aspirated. The mits. evo makes 295hp with turbo intercooler and bov. Without all that it only makes about 150. Put a turbo on an s2000 and ull get about 350hp easy... but then there are other factors, like durability, max hp it can take and how long it lasts. Still f20c owns.
