I have seen a throttle body from a Q45 used
Dont ask me how it was done
it was along time ago
But maybe you can search for something about it

thanks for referring me to the 2jz manifold q&a section bu it didnt really answer my question.

Has anybody used a 75mm or bigger on their 2jz style manifolds?

I got an 80mm Q45 TB I'm working onto a custom 2JZ style manifold. TPS already bolts up. Just been busy with other stuff but I really do need to get back on it. our TB next to the Q45 TB looks like a Civic TB

I've installed the Q45 TB on my custom foward facing intake manifold. The 7M TPS does NOT bolt right up, nor is is compatible with the Infinity flange arrangement. Modification is necessary. You can cut/weld the 7M TPS flange onto the Q45 TB or implement some other innovative methods. Also, the Q45 TPS is a 3wire system, while the 7M is 4wire.
the TB ID is 84mm
OD = 90mm.

My mod'ed Q45 TB to accept 7M TPS:

I've installed the Q45 TB on my custom foward facing intake manifold. The 7M TPS does NOT bolt right up, nor is is compatible with the Infinity flange arrangement. Modification is necessary.

Yeah sorry for making it sound like it bolted up. I did have to modify the TB for the TPS to bolt up but it can be done and it isn't too hard.
