No-you wouldn't.

Not much you could do anyway, without re-engineering the fuel delivery. By the time of your ZX, emissions equipment was pretty thoroughly integrated into the factory fuel injection. There's not much that is removable separately.

That will be a big task. If your dead set on this you might be better off planning on changing the whole intake system. I'd consider carbs

It would probably help you answer your own question if you defined/learned what each item of "crap" is and how it functions. Then you could determine how removing it would affect performance.
