If you're using redstone engines you need at least 4 to get results and if your pumping water into more than one combustion engine it's critical to keep the water moving fast so use a steam/stirling engine or 2. If you get tired of feeding coal into the steam engine all the time, use pnumatic tubes and a transposer from a chest to supply the engine.
