yeah, no doubt it works Mat but it's efficiency would be compromised. The turbo should be allowed to force the spent gases out into the manifold whereby an external gate is used, free of interference, then the wastegate can discharge gases either back into the zorst system or straight to atmosphere. It seems to work more like an internal gate?
I'm stumped why would you do it unless it was a space-saving exercise? Just curious to know that's all........
I seen alot of custom set ups, in particular, specific manifold design which can be complex & even seen twin external screamers made to go into a single wastegate where most use 2 seperate pipes & gates. Also, do folk realise how hard a steel the turbine exhaust housings are? Extremely hard steel to cut & drill!
Chewy, again, I luv the project man
