LUCKY FOR YOU, i own a supra and an IS300 (just got my supra 3 weeks ago, VERY HAPPY).
Anywayz, i ended up giving up and getting Supra TT. What did i give up on? Putting a 2jzgte, into a IS300. To me that was the best setup. If your gonna do it yourself there are some of the issues you'll have to deal with.
One of the firsts is the crossmember, supposedly it gets in the way and has to be bent or refabbed. For the wiring it actually may be easier to use a Supra ECU. I HIGHLY doubt the engine mounts gonna be easy to do, and i dont think the is tranny will mate with the 2jzgte well, if at all. Anyways your better off using the e340 (supra tranny) then the IS300 one. EVERYBODY has been having problems getting the IS300 to shift under high boost. I would use a Supra rear end.
Powerhouse Racing supposedly has done the swap (although NO one has ever seen it, but its Powerhouse, so they know there stuff), but its only available for 5 speed IS300s.
Area 51 Fabrications/Climax Racing just finished a 2jzgte swap into an Lexus GS (auto obiously), and its supposed to run 600rwhp when tuned. I have very good relations with both Area 51 and the GS owner. So all in all, it very hard to do, but Very possible, no one has the guts, funding or drive to do it, but the first one that does...OH MAN!
