cuz if u didnt, u should and get it port to match the intake manifold because that's where a lot of your power will be!! an as far as ur spooling goes the big the turbo the slower the spool but the more power u make ,the smaller the turbo the faster the spool but less power!! 63. ex 70 a/r sounds good !!im guessing ur goin to be running high boost most of the time!!!
Not that necessary for a turbo setup. What works well for naturally aspirated power doesn't always hold the same. Yeah, it might gain a little power, but really all you're doing is making a volumetric efficiency improvement by porting the throttle body. A turbo is a much bigger volumetric efficiency improvement, and will far override the effects of porting on a moderate power setup.
Basically it's not something to worry about unless you want to make fairly big power, and having a bored throttle body can definitely have bad effects on off-boost throttle response because it will slow down intake port velocity.

That will work just fine.
