Some items/block missing?

[Filarel]

Hi, 

I am from Poland so my English could be not Perfect. I already watched a lot of polish tutorials but they are from 1.5.1 and I am playing on texkit 2 1.7.10. I was trying to do some mechanisms on Creative but I dont have f.e. Redstone Energy Conduit or Magmatic Engine. I was searching whole internet and I wasnt find anything. Do I have missing something or bugged or it is Just replaced with some other blocks? I need the energy conduit to connect engines to some machines but there is nothing. I have thermal expansion because I have f.e. Redstone Energy Cell. But no conduits. Where are they?
