as said above there power input is a problem, redstone engines give 1 mj per tic, a quarry need 10+ mj per tick to be effective, so 2 or 3 Stirling engines or better still 2 biogas engines will get you off the ground, really mate google some info & builds, if I didnt know better I would say this was a troll topic..........
Redstone Engines will no longer provide power via wooden conductive pipes, i.e. they can no longer power anything they aren't directly facing. Say goodbye to those oddball Let's-power-a-quarry-with-a-bunch-of-redstone-engine systems, among other things.
