What side is your compressor housing on

Any one else notice that on these home made turbo web sites when they adapt the turbo to the hf or std manifold that the compressor housing is on the opposite side to the greddy kits. So for a 92-95 or up civic there would be no space if you wanted to run your air filter to pull in cooler air. Assuming of course you have a/c and power steering. Does anyone know why it could not go the other way is it because it wouldn't line up with the exhaust port from the header with out the turbine touching the engine?
