There is an easier way of putting a turbo engine into a yaris. Im suprised no ones even metioned it before. Buy youreself a yaris with the daihatsu designed 2SZ-FE Then go and get a Daihatsu YRV Turbo from a breakers yard:

Should slot right in. The k3-vet that comes in a YRV Turbo is essentially a 2szfe with a turbo strapped on giving 130bhp from the factory!
