Internal is a Beancounter's solution ... External is a Engineer's solution ... there should be no question as to which Is a better solution
Do some research on Borg Warner turbos as they have brought turbo technology into the 21st. Century with an internal waste gate that can be electronically controlled.
The engineers did this, not the bean counters!
If the 200 MPH Indy Indy cars can run the B-W turbos for 2 years without any maintenance or repairs, they must have done something right, simplicity at its best!
My next project will feature a B-W turbo in a 9-10 sec. street car, the engine is sitting here and other parts including the turbo are on the way.
I would do what RJC tells you unless you want to do your own R&D .. just sayin
When I see how my current assembly is hanging up I will decide then, but thanks for the comment.
No offense but I've used BW turbos since 2008 on non-Buick applications .. I know exactly what they offer up and how they perform... Impressive comp maps for sure.
BUT putting on a EFR to a buick isn't a simple bolt on ... a EXT GATE downpipe is and the benefits are more than obvious.
Whats the commonality between a INDY CAR and a Turbo Buick car driven in the street ? ......... .
The BEST material to use for wastegate actuators is inconel. 304 stainless is a temp fix at best. We have run integral wastegate at 9.9's for many years. Choose the right material, and do it once.

It would be shocking if anyone ever did. Still a good question.Who makes our waste gate actuator in inconel?

I should have been clearer. Not the puck, but the hinge insert should be inconel. It also cannot be a tight clearance with the puck shaft. Loose is good. Kinda goes against better judgment.
I posted a pic of a 3.5" oval downpipe (stainless) I built for a TTA years ago. Yes no one would want to pay what it really costs to fabricate quality. I think I had 40 hours and $1800 in materials in it. It did work well, though.
Do you happen to have a part number for the kit from TA?I just got TA part took me 20 min 15 of it to find my grinder
