There's no reason to change the manifolds unless they physically don't fit. The oil pan depends on the subframe. You'll need engine mounts that fit too, those would need to be fabbed if the Supra mounts don't work. The transmission depends on whether or not you can get a bellhousing that matches or if there is a RWD transmission with the same exact bolt pattern. Adapter plates aren't a big deal, an expensive adapter is $300 and most of the cost is for design, the pilot shaft length is a bigger concern there. Unless the Supra bay is really short with the 2AZ the belt accessories will probably be fine as is.
There are quite a few variables that really depend on the engine and the engine bay, the biggest problem is meshing the engine ECU with the rest of the wiring that would kill most swaps even after everything else is done. New cars have a second Control Unit that handles the body controls. I know it can be done. But I'd exhaust other options swaps if you're looking for cheap and easy but not necessarily better.

A lot of the fab/machining me and my buddy will be able to do (75% chance I will be getting to rent a 3 car garage for cheap!!!). The intake manifold is the question, depending on what side the throttle body is on the FWD car, it could end up facing the firewall on a RWD placement.
I'm a machinist and my buddy's a welder. Plus I know a guy that does excellent wiring/piggy-back/standalone install/tuning for a fair price so that's not a big issue.
Now if Scion was promoting RWD conversions for tC's some of these could have been addressed. (RWD turbo manis for example...)
Doing it all from scratch adds a lot of time and a bit more money. Plus lots of swearing.
The plus side is if we do it all ourselves, and it's good, we could sell kits to ...open-minded Supra owners. (Obviously not in it to make money if I was trying to promote a Camry swap over a JZ swap to Supra owners...)
It's the handling benefit I'll be looking for. Maybe with 350whp (that seems to get mid-high 12s in Mk3s), that would be a pretty respectable Mk3 Supra that can actually handle REALLY well.
