Stock intake manifold still? If so, that throttle body is too big. A 70mm throttle body will feed most h/c/i packages more than adequately. If you have a combo that warrants a 75mm throttle body, then you should already have a manifold (made for that size throttle body) as part of the package.
As far as porting goes, you can do it yourself with a dremel tool and some basic attachments. I port matched my throttle body, adapter elbow and upper and lower intake manifolds with my dremel tool. Good luck!

Do you mean the CAI hose coupler to the intake plenum? the rubber hose won't fit?

Yeah, that's waaaaaay more throttle body than you can use at this point. 65mm would have been much more suited to your combo and would have still been good after you get heads and an intake. I guess this means you have to break out the credit card and buy some heads, an intake and a new S-trim to make use of the new stuff. Bummer.
