That's a pretty lofty goal that few have reached in an aircraft the size of a KR1. Richard Shirley comes to mind with his KR 1 using a Jab 3300 but I don't recall if he can "cruise" at 200 mph. There are some books you will need to purchase, I don't recall the title but "building for speed" comes to mind, that will help you to build an airframe capable of those speeds on limited horsepower. It may not be the KR1 you're looking for. As the speed doubles, the drag squares. Doubling the horsepower will not double the speed. To cruise at the speeds you're looking for on limited horsepower, you will need to build very light, very slick, and fly very high. It can be done. Good luck........ I'm not enough of an engine mechanic to advise you on engines. That's why I fly behind a Continental 0-200. Both VW's and Jab's have their concerns. The VW concerns have been expressed here on the net and, of the three Jab powered planes at my home airport, all of them have had engine problems. Nothing mechanical is problem free but my 0-200 is pretty much like a rock, even if it's dropped it doesn't break. :-) Larry Flesner
