Default Converting Internal to External WG

I'm assuing that this can be done, but wanted to see if this idea is feasible:

1) Weld up Internal WG flap in turbo.

2)I have cast manifolds, but have an old contact from an engineering company I used to work for that can weld a WG flange to my manifold.

3) Modify downpipes to accept WG dump.

What do you guys think? Am I completely nuts?

yes, or you can also remove the flapper door and split the dp flange so the exhaust from the wg hole flows into an external wastegate

I was thinking that as well, but how can I "seal" the wastegate dump from the turbine dump? Turbos in question are 3076r Garretts.

depends on if the turbine housing outlets are sunk in (swimming pool) or if they are flat and flush with the flange mating surface.

Anybody else have any experience with this? The kit in question is my APS TT system on my C6.

then find a place to drill and attach wg's to the log manifolds. since your turbo outlet is sunken in, you'd have to weld a divider in to seperate the WG gas outlet from the turbine outlet.. not worth it. end of story.

Why do you want external wg's btw?
