95m goes kinda fast for kinda cheap

Alright so today I'm having a minor panic attack about the health of my motor. I finished my exhaust except for a vband leak somewhere, doesn't help that I stripped one of them. The exhaust doesnt contact anywhere but comes damn close to the trans and subframe. Around 1/4 of an inch. Again trying to trace the leak on my down pipe and more water in the exhaust system? Also when starting up it runs fine when my wideband is on heater but once it warms up it leans out and it dies. Which I think is the leak before the o2 sensor so oxygen is present=lean. Is it a problem to lean out at idle? So some minor ms problems to sort out like idle control and fan control and trying to get autotune going.
The only thing else I did engine wise is switch to a 1.6 bk6r plug from the bk5r plug. Yes the downpipe is rough but it moves gases. Exhaust is 2.5 inch straight to a thrust muffler.

Didn't realize how much I suck at pictures. So far the car is running and driving, to and from school. Tuning strategy is good afr's via ve analize, which I love btw. As well as a set of Det can headphones. Still getting boost creep which prevents a full wot throttle run. Cashed out on Dremel bits and will do a nice port job tomorrow. Stock clutch isn't loving it, so the beefy act clutch will be going in soon. Also new england goes from 65 degrees on april 3rd to 4 inches of snow on april 4th and 5th, god (or whatever you think it acceptable here) hates miatas. So next purchase will be some Kosei K8R's 15x8 from tire rack as well as a set of Kumho ecsta v720's in 205 for a summer tire, when ever it comes.
So what I originally wanted this build to be, and what it will be, is very similar to tekel's 95 turbo. A cheap churbo street car that has good suspension, brakes, tires, and power. So I think its pretty close to that

Ok I can't resist, as an SF native who survived 4 harsh New England winters and is happy to be back in sunny California.
The universe, unicorn, god or whatever loves miatas he just hates New England.

Mine was a lot easier, the 1.6 manifold has the turbo like three inches forward of the 1.8 manifold, and it's up a lot higher, too.
It's why I'm having Lars make me a manifold for my 1.8, his manifolds are closer to the 1.6 tacotaco. I won't have to change my downpipe much at all.
But here's mine...

You should be able to set the wastegate preload loose enough to hear it rattle around at idle, if it still overboosts then you either need porting or a new wastegate can.
You could also use a bike pump to check it yourself if you wanted. It should be around 7-10 psi or so.

A bike pump is a good tool for wastegate testing. I recently rigged one up to find the max and min duty cycle of my ebc solenoid. It was very easy to see on the gauge, 7% closed, 98% open @ 19.5hz for those who want to know.
