Someone will definitely be a troll and put an LS engine in the Supra for sure !
But these engines aren't going to be capable of holding as much power as the 2JZ was for obvious reasons like the materials used in the engine construction and what not. Give it a while when aftermarket companies start making internal upgrades, sleeve the engine, and you should be good to go to start throwing real power at it though.
I have been long awaiting this..
