the 7MGTE out of the MK3 supra is a common swap and doesnt require much to do. Also the you can swap the 2JZ out of the MK4 in but theres a lot more mods that you would have to do than if you were going to swap the 7M. But a few people have done it so it is possible. And the 6MGE it pretty much a direct drop in. Look on celicasupra.com and go to the forums and use the search button.
