Hmmmm, I don't think the 1JZ/2JZ FFIM will drop into the 7M without any modifications. I know there is a couple of people that makes the 7M FFIM, one is Seth, Ron, and Lipp(I don't think they finished the prototype though).
I suggest doing a research first before you decide to jump in. It's not something cheap.
