 Changpuek managed to push the much larger Hoost into an extra round only to lose eventually via a head kick knockout.Although Changpuek would never again quite hit the peak of his success of the early nineties, he fought a number more times with the K-1 organization, the highlight being a victory against Nobuaki Kakuda to claim the W.M.T.C.cruiserweight world title and wins against the likes of Kakuda were tempered by defeats against Michael Thompson, Ivan Hippolyte and Manson Gibson.
