Hey man, I've looked into doing this swap on my yaris and did a lot of research into it. For the cost get the engine in and running right you may as well buy a GT Turbo or Glanza. There is a lad on the yaris facebook page that is doing the swap atm and a few others that have done it before but it's a very expensive swap. If you are set on doing it post up on there and there is a few people that will give you some good advice.
