I found it easier to get started with the hoses I had from the M52 donor and go from there!
From memory, I re-used all E36 rad hoses but just cut them down where required (I used a rad with expansion tank built in by Direnza)
I replaced the two hoses to the heater matrix with silicone 19mm stuff and various degree bends etc to ensure there were no kinks and everything cleared the M50 manifold I used. To connect that up to the M52 head and hard pipe you'll need a 21mm to 19mm straight reducer and a 24mm to 19mm straight reducer. In hindsight, I would suggest the reducers and then 1m of the flexi core silicone hose by ASH. That would work out cheaper than all the bends and connectors I ended up buying!
I went with a Mishimoto silicone intake elbow with 2 outlets (for ICV and rocker breather). This allowed me to use E36 airbox without pushing it right down into rad / headlight!
