I doubt that dropping all of the emission controls would see engines getting significantly simpler. They would still be utilising common rail fuel systems, 4 valve heads, variable geometery turbos and the like to get the power and efficiency. 200hp 4.5 litre, 4 cylinder engines are just around the corner (I think there might be one on sale now), I doubt you could get that kind of performance with an old inline pump.
