Water hoses

Can someone point me in the right direction for the hoses that will need replacing on my m52?

Do I need all the hoses shown in the below two images?

I'm putting in a big order for parts from bmw this week to which I'd like to add as much as I can. Or should I go else where, are there silicone hoses available?

I don't know how my radiator effects the setup, I have a alloy M3 rad and a separate expansion tank. I will also be fitting a m50 manifold with the engine.

That would be a very expensive way to pipe it up, plus you will be cutting most of the hoses down.

I was thinking as much

Any post anywhere showing what hoses are needed and what has to be trimmed etc?

E36 top rad hose works when trimmed a bit, ive been using E46 bottom hose lately they fit better with aircon compressors. Throttle body hoses are deleted, the heater hoses are easy, just use one E30 hose there and the other stays. Then the last one from the steel pipe to the expansion tank doesnt need touching either IIRC

No aircon though, can I still use a E46 one? Any 6 pot e46 I take it?

I've got the top rad hose and 2 long ones on the engine, one goes forward the other back wards of the engine. I don't have the big long one in the first image above, no 6.

Didn't seem to have much else attached to the engine, might have something removed with the manifold. I'll pull the hose of the m42, is it the top of bottom one or does it make no difference?
