2008 150cc bashan to 250cc water cooled

[xnitro]

Just wondering if anyone knows if the 250cc engine would fit the mount on the 150cc mount, thinking of installing the 180cc big bore kit with all the goods. That adds up to about 1800.00 dollars. And possibley will not be enough power. So I was thinking of installing a 250cc set up in it. Any information on this or is it not possible? Would like any input that may help?

Thanks xnitro:!8)
