Played a bit more with positioning of the pump. It is a bit tight, but I'm quite positive it'll fit. So I ordered a pump with remote reservoir and which includes the volvo bracket and rubber suspension things. Maybe that helps a bit towards the final positioning and bracket.
Meanwhile I have taken the Boxter S cooland pipes out of the wreck as well as the coolant pipes out of my base car. I didn't quite imagine the difference would be so large:
Looking at the area of the pipes on left / right sides, it is a very significant difference:
Another thing I didn't realize is that basically everything between the engine and radiators is different in diameter. So not just these pipes and relevant hoses, but also the short pieces of pipe in the wheel wells and hoses to the radiators.
I'll keep my car double radiator for now, so I need to find two additional hoses (as I won't be using the T-junction hoses towards the third radiator). All other parts (including clamps / brackets etc.) I can just transfer from the wreck
