Thanks for your views I think I will crack on with the fit.
I will update as and when. I was thinking would it be possible to fabricate some new pipework that will go from the turbo and into the 965 turbo style turbo inlet pipe and do away with the part in the picture. If that is an option what would be the minimum internal diameter of the new pipe I could use. As there may be an issue squeezing the two pipes that come up from the turbo through the narrow aperture.
