Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Tyler, piggybacking on our conversation from earlier, I think a modified version of the solution I showed you may be a good option; putting the gate inlet on the turbine housing, right next to the T3 flange at the bottom side. You could simply add a 180 degree section of tube that hugs the turbine housing and puts the gate assembly close to position 1. It would be less bulky than the adapter that Chris showed while putting the gate inlet in a more optimal position.
If the extra tubing isn't a big deal, I think I'd want to do exactly what you're saying. Keep the hole in the housing close to the flange, before the scroll part of the housing, and run a pipe to mount the wastegate next to the turbo. Then we could also add a little bracket over to one of the housing bolts to help it not crack.
Chris, if Harald's idea doesn't work, something like what you linked might. A t3 to t3 90 degree (or a bit less) could work, with a Y off the 90 degree part. I would have to take some more measurements, though, because that puts things pretty close to the hood, since my engine is upright.
I think the real solution here is to raise the boost, max out the turbo and not use a wastegate.
Use schedule pipe for sure, and even then hanging a gate off a long stretch of pipe is asking for failure. Pretty sure those small gate flanges accept 1 1/2 schedule pipe nicely. I've done a few turbine mounted gates and they all worked okay. I have done one similar to your first pic on a turbo v8 with a 50mm gate. Previous combos with normal gate mounting I can normally control boost to sub 5 psi, but that turbine mounted one wouldn't make any less than 12 pounds even with a 3 pound spring in the gate. Ones with the gate right after the flange worked great as expected.
Come on, I'm a visual learner. Plus, EivlEvo up there asked for a picture. I'm just giving the people people what they want.
Good call on a heim joint. I think the current plan is to use a schedule pipe welded to the housing, then a flex section, and the rest could be normal exhaust tubing with a bracket. I feel pretty good about that, so we'll see how it works out in real life.

You'd probably get enough flex/expansion out of vbands no? But maybe too much leakage?
Nice drawing. I made infinity of those at scout camp.

I was just continuing the Napoleon Dynamite theme with the scout camp reference
I would have it exit the housing at the 8 oclock position like in post #10 with a bend upward to put it where you want and not worry about bracing it. It wont be easy to find a bellow that fits the OD of schedule pipe and it will just add another failure point. I assume you're recirculating back into the downpipe? If so definitely but a bellow on the gate outlet tube to keep it from tugging on the gate.
