boxter/cayman tuning

my question is actually concerning the cayman. is it feasible to swap the normal 3.4 liter for a 996 turbo motor. what would this take new mounts. custom body work. rearranging/removing to fit the turbo plumbing. would it just be more cost effiecient to turbo the existing motor. and are there even kits out there to do this for this series of motor. by the time you add up the price of the actual turbo system and all the bottom end components i could imagine youd be looking at 10s of thousands. i love 911 turbos for the power, but on the other hand i love the quintessential layout of caymans and i want the best of both worlds
