Now I am looking for a solution to the sequential additional injection, but it will be very difficult for realization, as far as I could visualize it in my head.
First the manifold is plastic and welding would be impossible, so I have to design something unusual using the strapping points for the manifold plastic cover(In the picture above this cover is removed, as well as I did it a while ago). If I manage to solve this problem I will be facing the space shortage between the manifold top and the engine bay lid (bonnet/hood). However a 45 degree boss install would save some valuable hight and finally it could be realized but there are a large amount of unknowns in this equation. :? :?
I will research the google images from cover to cover on this topic and hope soon to post some ideas for discussion.

I am happy to say that I really hit the JACKPOT by registering in this forum. Thank YOU!
