Re-Attaching all of my Cut Corners
The MKTurbo kit is well thought out and solid. I did have a few changes I wanted to do, however. First I ported the wastegate on the turbo, I also ground a little channel so the flapper has more clearance and can open about 1/4" further.
Then I ported the manifold slightly, cleaned it up, and painted it. Instead of using the MKTurbo hardware, I picked up a set of TSE Inconel studs and installed the turbo using those. I am so excited about not having loose nuts any more.

Glad you like the v-bands, they do make it a breeze to install. Exhaust is large, but once you start driving and realize how nice it sounds you will forget. Also I recommend that you get 5 large coolant hose clamps and put them over the rubber exhaust hangers and tighten them up. This will help prevent them from sagging from the exhaust weight and help keep everything from possibly moving as much.

You are ballsy running 20spi so fast. Good for you. I hope you are enjoying it.

Shoot me an email later on if you ever want to upgrade to the larger turbo. Sonofthehill is running it and he says it holds top end boost a good bit better. I would suggest maxing out the one you have first and figuring out if it is good enough to make you happy. I am very happy to hear that you love it.

looks like you have a pretty significant restriction in your intake tract too if it's tapering that hard.
even with the terrible signal source you're using it shouldn't drop that hard usually

I don't think pipe size is an issues. People have done the math and 2" flows far more air then a stock miata motor will take without blowing up.
Sonofthehill had similar issues with the turbo holding up top. I think it more just comes down to it being a china charger and not a baller EFR.

more like cold side.
internal flow is not impacted by external damage unless you got the tubes completely dented somehow.
I mean, you're running a cheap setup with a chinacharger, I guess its probably not worth it to pursue major efficiency improvements, but you can easily test my theory by logging boost first at turbo, then at IM
if the difference is less than 2-3psi, then do what lars is suggesting

I have not tried my crazy wastegate can on the smaller turbo yet. I am not yet convinced that I wasn't just blowing the wastegate open at 6200 or so. The new can is capable of holding it shut with an incredible amount of force, especially near 20psi.
I have not decided what my next step is currently, except to run the large one for a while. Maybe to the end of drag racing season.
