Minecraft 0.45 4x4 Piston Door

To enlighten you, why I'm posting a "copy" of the door is that this one has better lever input and more in sync animation.
I'd like to give a special thanks to Sacred Redstone and Space Walker for creating the very first version of this door! Then I'd like to give a special thanks to SoulBanished who helped me to make this door modification.

Is it possible without input delay?

[@amsard4953]

Yes, but not in this size, it would need a complete rewire. If you want to have it this small, there needs to be something else than lever powering the circuits straight. As you can see there are 2 repeaters down there powering it. Edit: I just tested something. It is possible to make it without input delay, though the circuit must be fit outside of this door circuitry.
