Its a massive job. Everything Toyota-related will have to come out. You'll need something like a Chevy SS/Pontiac G8 (read VE/VF Holden Commodore) or Camaro SS as a donor. The Commodore ECUs have a fair bit of scope to tune them. You'll also need to overlay the two wiring looms and somehow merge the engine and trans loom to the body loom, which is easier said than done given the UCF30 has very deep CANBUS system integration; nearly every system in the car has some sort of computer controlling it. Then you'll need custom headers, engine mounts, transmission mounts and crossmember, driveshaft and more than likely a stronger diff, as 6 litre LS engines (LS2, LQ4/9, L76/77 and L98) have a lot more power and torque than a 3UZ. If you have the time, money and/or skills to do this, then the world is your oyster, as LS and Junkyard motors love boost
