are you able to get a hold of a supra that already has the 1j swap in it? that would be an awesome buy....
the swap has it's ups and downs lol... this might help...

the 1jz does have a 50hp headstart and is not prone to blowing head gaskets as 7m's are from the factory... once you get a metal head gasket and arps and prep the block and head surfaces properly you shouldn't have a problem... i believe they have quite equalish potential but the 1j gets there faster i think... i'm purely biased and go 7m power all the way lol... parts at the moment are quite easy to source for a 7mgte but 1j parts are still a pain to get....
really you need to decide on what you're looking for out of the engine
what do you plan to do with it?
