I have searched and searched for information on how to modify a stock a 12 carburetor to except blow through turbo. There's a lot of information that is all very similar but when it gets down to specific modifications to carb , it is vague .
Is there a detailed thread regarding blow through turbos on A motors ?
Specifically modifications to carbs including parts part numbers ?
Do you have to modify a carb if you build a full enclosure around it ?
Do you have to modify the carb if you use a top hat ?
The turbo I'm using is off of a 650 Yamaha seca bike.

Did you post this question on Datsun1200.com?

An idea doesn't work unless you do.

I guess I'm just gonna try boxing the whole thing in it makes the most sense
to pressurize everything as one and just monitor the tune.
Where just hope I don't lean it out and fry the thing

You may have already looked into the basics, this:https://www.youtube....?v=q4h69sTB2Dk 

is an example of what you are looking for only a bit larger engine, a 280Z, but has good explanation of the components used and why. Perhaps this  may help??

Wow that guy really doesn't understand why a pop valve is needed at all. All of his electronics are not even secure...... HALF ASS.

If you box and pressurize the whole carb, you'll still need to increase fuel pressure proportionately to boost.

It leaks oil, gutless, . It's left me stranded a few times now. I'm going build the R16
To drop in. Then build the A12 up as a spare or to sell . When
I bought the wagon, it had issues. Fixing my DD is tapping out my wallet
And it's hard to buy anything anymore for the wagon knowing that a
It was a hack job. Haven't taken apart the A12 so it's always a gamble.
That was a bit winded lol but that's just proof of my stress with having a hobby
Like this .

Swapping out the A might give me a chance to build it and set the turbo up
And answer some questions we all may have .
Just a bit of positivity.
