turboing a sohc

I am thinking about puting a turbo on my sohc civic ex. I know, get a swap first..well one of the reasons i want to is because there arent a lot of turboed sohc's out there...i dont want to be like every other civic...my question is: what do i need to do to the engine to get it ready for the turbo...internaly...it has 111,000 miles thanks a bunch
