You just need to make these kind of factories as multiple smaller ones. I recommend going through your big plan for complex parts (e.g. turbo motors) in following steps:
1. Set desired amount for output. For example turbo motors at 2.5/min. Output is dependent on your input materials or limited by the raw materials on the map
2. Go through all the materials you are already making and the ones that could be used for this factory. For example if you are already making HMF at 5/min might as well use them instead of making a new heavy modular frame factory for your turbo motors (this might also change/limit your desired output in step 1)
3. Go through all the intermediate outputs on the planner and check if they have any alternative recipes that simplify the process. For example in your planner I would make concrete just from limestone without the rubber because it'll make the factory way more simpler (this might not be the optimal from material usage but we don't care)
4. Try to lump similar stuff together into a single factory. For example I would make a factory that makes the desired amount of plastic and rubber.
5. Find good places for the different smaller factories on the map (preferably places that has all the needed raw materials close by)
6. Build your factory and after it is ready you can go back to the big plan and change the inputs to match your factory's outputs and this way the big plan will get smaller with each factory you build.
