Removed the compressor but i was wondering what else can go without disturbing anything else - piping etc, pics would be handy.
pipes and condensor(radiator) are obvious targets, the evaporator is inside the air box is a bit harder. removing what you can see and get to in the engine bay wont do any harm is the best answer. might be worth bunging up the pipes into the car incase you ever want to put it back, at least you will know its not full of cr##p then.
