BBKs are lighter than stock, and aluminum chassis stiffening is a matter of tens of pounds, not hundreds. Even being conservative you’re looking at 400-500lbs lighter of car, assuming you don’t strip weight elsewhere (battery, seats, etc).
You’re not getting something for free, you’re building a purpose built racecar or “racecar” or hotrod or drift missile or whatever you want to call it, instead of a pseudo-luxury sportscoupe. The “cost” is in that you’ll have a loud, rarely, harsh racecar instead of a car you can drive to work every day.

On some B58s it has a manifold. The engine has an intake manifold with an integrated water to air intercooler and an intercooler up front. It has a turbo system with more actuators and sensors than the FA20. It has a larger radiator. The transmission is larger. It has two extra cylinders. I can’t imagine saving 80lbs of weight with this swap.
The point about the adaptive suspension, active diff, stiffer chassis, etc is that the Supra has better components which is why it is heavier and is why it has more value. Again, by the time someone completes the swap, they may end up wishing their Supra clone was just an actual Supra, especially after spending Supra money and having less quality parts.
Like I said below, I agree with you that a racecar is the most logical application for this setup. Also, it could be cheaper trying to make the 86 more powerful with this swap than trying to make the Supra lighter. It would be hard to remove sound deadening; it would be hard to remove and sell the adaptive suspension system in order to install static compression; it would be hard to remove thickness from the subframe or suspension components to match that of the 86; it would be harder to remove quality from the interior without a full strip; it would take more effort to swap to a smaller brake setup to match the 86. I agree that this swap is most logical/cost-reasonable as a racecar likely using a used, higher mileage 86 along with a basic ECU package just to get the car running.
