External Wastegate Dump Tube Question Newb ?
What part of the dump tube would need to be modified to run an internal wastegate? I thought I'd be able to just section off the dump tube portion of the downpipe and cap off the wastegate hole on the exhaust manifold? FM told me there's more to it than that.
I thought internal wastegates just vented to atmosphere and dump tubes weren't necessary.

Basically you'd need to connect the external wastegate pipe portion of the DP to the DP turbo flange right next to the main turbo outlet where you'd typically have the internal wastegate and drill out the flange as well. Internal wastegates dump out into the DP either with a bellmouth DP or separated as you see in your pic. If you just drilled out the turbo flange where the internal wastegate is you'd have exhaust emptying right out into the engine bay.
