Well, they made that exact boat with 510hp(sorry, I read it as a 230 and not a 210, next paragraph) so it all fits fine as long as you use the same parts. However, I don't think there is a big difference in performance between the 510 and the 430, maybe a little stronger acceleration and 1-2 mph. I suggest you take a ride in a 510 before you spend all the time and money for the conversion which you will have several thousand dollars in converting.
I'm sure there is plenty of room to add intercoolers. The easiest thing would be to add a fizzle ic kit. The skis have way less space than the boats and they make those work so boats should be easy. Not aware of anyone who has done this conversion but I'm still skeptical how big the gains will be versus money spent.
