The belt cover doesn't make it inefficient, its just a belt cover that's going to make no difference to the efficiency.
It keeps the dirt out of the belts, and more importantly it is a central stiffening spine. Take the belt cover assembly off the car and you will need to replace the top deck with a one piece deck as the ZX chassis is too flexible with the ZX separate top deck pieces. The normal ZX without the belt cover just isn't stiff enough unless you fit a ZX-R top deck.
The biggest reason for removing the belt cover assembly is that it makes maintenance much easier, which is why everyone did it. Nothing to do with performance. With the central spine in place if you need to remove the front diff, the layshaft, or even just replace the front gearbox case, it involves a complete disassembly of the chassis to remove both gearboxes at once so you can take the cover out as it prevents you from taking the front belt off the pulleys with it in place. Without the belt cover maintenance is so much easier as you can work on either end without disturbing the other gearbox.
It also makes getting batteries in considerably easier as you can lift the belt up to pass a battery through the chassis, than having to get the battery under the belt cover.
