Never seen one yet.
This isn't the sort of project that you just buy off the shelf stuff for.
Since it's a 22R, you'd be much better off buying the EFI hardware from one in a junkyard, adding a megasquirt and turbocharging the fuel injected engine.
Much simpler and better control in the long run.

this 22r is the earlier 22r that the efi is not swappable to i believe. i have seen 4 barrel holley carbs blow through ready but i have a feeling that might be overkill

I know Holley makes a supercharger ready carburetor.
Why not consider a carb adapter (might have to diy something) and use a Rochester TBI unit from a GM Tech4 engine with a Megasquirt.
Whatever you do with a turbo and carb be prepared to throw it away and start over if you really want it to work.
If you stick a carb in a box. Build the box so you have access to the screws as you try to adjust it. You can get it to run, maybe just keep throwing more fuel at it until it stops backfiring
But the simple truth is as pressure increases mixture has to increase accordingly. Carbs are draw through devices.
Superchargers can be kludged to work because the pressure on increase isn't so big. 6-7 psi is about max most street blowers typically go to . It helps that a supercharger heats up the intake charge so much. Because that heat helps an overly rich mixture to vaporize. The heat also limits how much boost you can survive with but I suspect you already know that and you just want to do this for fun, right?
In the end if you'd like a power increase you'll have to accept EFI. Which is really simple to dial in. Some aftermarket units like mega squirt are self learning and all you have to do is connect everything right and it will start right up and get itself close.
If like me, you are terrified of EFI it's something the guys here will help you with. It's like eating a big plate of food. Start out with little bites. And just stay at it.
The chance of an engine destroying mistake is tiny compared to what you're attempting to do.
