I've seen a 2JZ in an OLD Subaru station wagon... you'll be getting no slappage here.
As far as what you'lll need... well, I'd look for a complete front clip myself. You'll need at a minimum: long block, intake manifold and plenum, throttle body, intercooler piping, intercooler, turbos, blow off valve, exhaust manifold and down pipe, ECU, engine harness, dash harness, fuse box, igniter, coils, an electric fuel pump that is made for EFI systems... all the usual stuff really. I can't think of anything else i'm missing at the moment. I'm sure someone else will chime in if there's something to be added to the list though.
