1/2 VW 32hp convert to the 45hp??

[minimaxjon]

Hey everyone probably a dumb question here.... I am curious if it is possible to convert or upgrade a 32hp 1/2 VW to the 45hp 1/2 VW. I noticed on the engine spec page on the hummel website that both are available in the 1/2 vw case...
Is it possible and what would i have to do to change it over if it is?
Thanks
Jon
