I have some money to blow... Ive been tossing back and forth the idea of putting a K motor on boost into a hatch, or building a B and putting it on boost in a hatch

Im Most likely going to get rid of the eg I have now and get an ek
Im going to be doing alot of the work myself as far as the swap and the wireing goes..

How hard is the K swap into the hatch and how much am I lookin at with a reliable K on boost?

What would you do??
