I get that you want a sleeper builds but there would be no reason to swap such a complex and large engine into a scion. To be completely honest I think you should look for either a <2005 Infinity to swap. They look great, handle fantastic, have a massive after-market community, and lots of people do engine swaps. In my opinion that is the perfect sleeper for a 2jz swap and has plenty of space for your little snails if you please! Happy Sleeping!
