Pack that uses Immersive Engineering as the main engineering mod?

I’ve just gotten back into mod packs after a long time away, and I’ve always LOVED everything about Immersive Engineering, especially the multiblock machines. I’ve been playing NeoTech for a dozen hours or so, and after sinking my teeth in, it’s clear that IE is not a huge focus of this pack. I tried googling for this but I couldn’t really find a good answer. The vanilla version doesn’t have to be the newest thing in the world so don’t worry about that too much.

Thank you for any help!
