Air pipes, I'm missing a few.... And an expansion bottle

Trying to get the car together within a month. Don't ask..
I seem to be missing some airpipes. One is the one to left of engine bay as you look in from front, it goes from intercooler hard pipe to Y shaped hard pipe.

The second pipe is a flexi pipe that connects to the plastic hard pipe that fits to the front turbo. This flexi pipe doesn't seem to have a seperate part number but looks to be part of the y shaped rubber pipe that connects MAF and turbos.

I'm also missing the wedge shape pipe that fits between front valance and airbox. I have seen one of these on eBay tho.

I also seem to have lost an expansion bottle. I may have lost my mind too but I get by without that easily enough. So if anyone has any of these to sell I'd be grateful
