The wikipedia page on the 914 2.0 states:
70 kW (95 PS; 94 hp) (US) 74 kW (101 PS; 99 hp) (RoW) Thats a significant difference. Is that due to the RON 91 petrol used in the US, or are the smog regulations the main reason. And if it's smog regulations, is there a way to 'undo' them? |

Yes, US pistons have a 7cc dish for a compression ratio of 7.6 to 1 vs the ROW had flat top pistons for a compression ratio of 8 to 1 and 100hp. That was the magic number Porsche wanted as the 914 2.0L really was replacing the 912 and the 914/6.
