Most people take the lower runners for the 7M and 2jz, cut them, and weld them together. I don't know much about it, but I think the 2jz TB is used with a little modification, you have to rig up a bracket to use the 2jz throttle cable, and make custom IC pipes. There are some good write ups about it on supraforums, I saved the links on my home computer (I'm at work). You should be able to search and find them, it seems pretty easy for what you get.
I have a 2jz intake, TB, and lower runners with all the sensors and attached hoses I was going to put on my 7M before I decided to go 1jz. PM me if your interested. ~John
