Hi,

Does it have to be a new engine ?
Otherwise you could just aswell buy an old type/style (used or NIB on the ussual sites) Webra or O.S. or Y.S wich ussually fit these older styles better.
I`m personally not such a big fan of the huge engines in these planes like the 75 or 90 with a good 60 and a pipe these planes have all the power they need and even a bit extra
so i don`t really see why one would put a big engine on the nose, but then again that`s just my opinion for what it`s worth
