2JZ Swap needs
 

So the 7mgte is coming out in favor of the 2JZ from an Aristo w/Auto transmission. I've spent several hours looking all over the interweb for info pertaining to what all is needed for the swap, and I've got most of it, but there's one problem. My '89 Turbo was made early enough to have the square cross members. Somewhere I read there is a bracket to fix that, but I've gotten nowhere with it. Also, if I'm buying the package deal with a 2JZ-GTE, including ECU, Wiring Harness, and transmission, assuming everything short of the cooling system is included, what else do I need to buy just to get the motor into the car and running?

You'll need a driveshaft to match whatever transmission you decide to use. If you're using a manual transmission you'll need a 1JZ bell housing for that transmission. You'll need a good amount of wire to extend the harness. I can't recall, but if you just use the adapters (sold by DriftMotion) instead of swapping the cross member and mounts for 89+ parts you may need a different oil pan.
