I'm interested in this too, but only going from the 2.0L to the 3.0L and staying N/A as I'm past the go-fast stage... I figure too that IS200 prices are much cheaper than IS300 prices and could be cheaper to upgrade a '200 around about the time the 150k timing belt change is due and get a 2JZ package put in then??? Can I essentially source an AU delivered 2JZ motor or IS300/GS300/ecu +5sp auto gearbox and replace this in the IS200 engine/gearbox, or is the diff a different ratio also needing swapping?
