That is true. The S2 was the standard 928S in '84-'86 outside the USA, but Porsche offered the 4 valve motor mit katalysator for those in the world who wanted it [This is NOT an S2, though the body was exactly the same] The versions of this motor for certain countries had lower compression, and as such a little less power. I have a German-language brochure at home for the '86 928, but I'm not home and I cannot remember if it mentions this variant. I think I read on one of the web forums that the versions for sale in Germany with 4 valves indeed made the same horsepower as the US cars, 288 hp. You need to lift up the carpet in your hatch, look at the white sticker, and tell us the country code. It is in the "options" field, and starts with the letter "C".
