Okay, I'd like to recommend that you do some research on the work required to build a supercharger kit. Youtube, forum posts (for other FWD cars) etc.
See the work & fabrication involved, what kind of parts you're going to have to make, etc. You'll be making brackets & machining custom pulleys at the minimum, perhaps a custom intake manifold or countershaft with bearing blocks if it's more involved.
In the meantime, I'd also heavily recommend looking for an XR2 parts car. Consider doing an XR2 drivetrain swap - it's very straightforward compared to supercharging, and faaaaar more economical. It is something any reasonably experienced shop can handle since you are not doing your own work at the moment. Still would be unique, there's very few OEM 94 turbos out there, even fewer swaps, I did an 94 turbo swap for Russ many years ago and I can't recall seeing any others.
At the very least this gives you the stronger transmission, flywheel/clutch, cable clutch pedal, axles, electronics etc that you will need anyways. It's always way cheaper and less headache to buy a parts car than to buy parts piecemeal, and you'll have *everything*
The Festiva guys are getting complete XR2s for $300-$500 for their swaps, many running/driving/rustfree which is a real shame. But the deals are out there.
Ignore twincharging, it's good on paper but a logistical nightmare and a moot point if you were to run a modern turbocharger - they are so efficient that it doesn't need any help.
And electric superchargers have come a long way from the $100 scams on eBay, but also not worth looking at
