Ive searched far and wide and cant find any info on swapping in a q45 tb. I found the wireing info thats cool, I was wondering if or what else I would need for the install granted ive got the upgraded injectors and ffim what else would I need for ecu management.

Please excuse me for being ignorant on this fact im new to the scene so any help would greatly be appreciated.

you dont need any special management, im running one without bigger injectors too. You just get your TPS wiring right and set it at .385 volts on the output wire.

what exactly would a bigger throttle body give you? more flow? increased hp? throttle response?
if it sounds good i might try it

what other mods do you have done?
I think you can spend the money elsewhere if you have nil to minimal engine mods.

nope. you have to build an adapter to wire the nissan stuff up to the toyota harness, or get the greddy tps adapter to use the supra one.

Then it must be slightly modified to work. I was the first to mount the Greddy adapter to the Q45 with the stock TPS and get it to work flawlessly.;)

on stock OEM TCCS,
NOTHING. Perhaps crappy part throttle response and that is about it.

The TB is sized for the application. The bigger the TB, the more air it lets in by sheer inner volume area. Anyway the fascination with the Q45 is quite comical when the Mustang 5.0 TB are a dime a dozen and come in all size flavors.
