Throttle body compatibility NB to NA

Throttle body compatibility NB to NA
I collected a few extra parts this weekend, including an NB throttle. My car has an MP62 on the '94 1.8L engine. The factory throttle body is still sticking on me despite cleaning it twice and polishing the inside. It doesn't stick off the car, but the moment it's bolted to the supercharger it becomes a pain in the ***. I can't explain it, it just doesn't open and close smoothly.
SO, I want to try dual throttle bodies with the NB body (cleaner, newer, smoother all around). I would like the NB body (w/TPS) bolted to the NA intake manifold, and the NA body bolted to the supercharger inlet.
My questions:
Will the NB throttle body bolt up to the NA intake manifold?
Is the NB TPS output same as the NA TPS output? i.e. If I can't bolt the NB throttle body to the NA intake manifold, can I at least use it to replace my sticky NA throttle body?
Sorry, rattling this off my head as I think of it. Ask questions if that all didn't make sense. thanks!

Sorry, what does the acronym mean?
Thanks for the info Savington. It sounds like my best bet is to go out this weekend and test fit it.
Yeah, Jfornachon, I have trouble understanding it right now too. I would hate to pull it apart again, but it almost looks inevitable to pull the shaft and figure out what's bad.

Sorry to bring back such an old/dead thread, but I have a question that seems relevant to the original post:
Will the IAC valve from a 99 throttle body function the same as the valve from a 97 Miata (are the ECU controls for the valves similar)? Will a 97 TPS fit on a 99 throttle body?
In other words, could you swap a 99 throttle body onto a 97, reuse the 97's 4-wire TPS on the new throttle body, and have it work normally without changing a bunch of other things? Looks like I might have to change the connector on the harness for the IAC valve, but would the valve itself still function about the same?
