Street Build ITFLYS - 1Gina2G

[Justin DuBois]

Awesome!
My drawing is kind of ambiguous down where I wrote in 2½ and 3½" for where the flap goes to, and I can't get a decent check on that with it in the car. But your O2 sensor is probably in a little different position anyway, since manifolds and O2 housings are different.
I never did tie down the bottom end of it to keep it from fluttering. So 3/16" clearance to the O2 sensor is about what's needed to keep it from ever hitting.

Gonna see how the paper template fits. Maybe there I can fingure out a stand-off and bolt solution for an additional hold down.

@Justin DuBois , did you have to port your TD05H turbine housing to avoid boost creep with the 20G?

No, the 15deg clip on the turbine blades are effective to address excessive spike, and creep.

Ok thanks. That's kind of what I was afraid of though. You did apparently feel that something needs to be done beyond just gathering up all the Mitsu parts and putting them together. That something was clipping the turbine wheel.

So, what got me asking you this is, @athlete3344 in this thread in post #15, is asking basically if he should go external wastegate to avoid boost creep, or if he should stick with the internal gate on the TD05H turbine housing and just try to put together a better actuator than what he has.
I hate to try to tell him what to do because I haven't done much with the Mitsu turbos, and I see the potential complications multiplying already. He has the awesomeness of a brand-new looking TD05H-20G turbo that has just been sitting around doing nothing for a long time, but a no-fit actuator.
Want to take a look at his question in post #15? Nobody has tried to answer it yet.

I did go with a billet internal WGA, so that I could increase the spring pressure. At Redline, the minimum boost I have is ~16-17 psi. I have not used an external myself.

I’ll take a look at the thread.
