So i went to see Plazmaman ( intercooler guys ) with my peices to be welded. They said it will be a week at least to go thru the process , welding cool down , pressure test etc. He was truly amazed and has never ever seen air end tanks milled :)
Anyway on to other parts.
Well i had the end water tanks for the second heat exchanger milled. Here you go.

Just to explain, 3 nipples. One and two are water in and out. The other one is for the connection to the windscreen water bottle funnel. The 4th opening is for a valve to bleed air out. Thought ild put a tapped thread on one side for a bracket to hold the nozzle for the water spray
Here is the side connecting to the frame of the car. 4 isolating rubbers to allow movement

This is the exit side for the water to travel to the first HE and the bleeding valve

This is the entry side with the inlet at the bottom and the filler nipple
