hi dan, welcome to the club.. where in the UK are you ?
as a suggestion before you get into modifying the box, i would recommend to grips with the handling, balance and control of the boxster. it is by no means a drag racer, but the box is not that it really is a superbly balanced sports car, get on the twisting A roads and see what the box is really capable of, then you may want to tweak it to get what you want out of it, or after finding out what it is really about, you may just be happy with the way it is.
