H23 intake manifold onto F22A1

[HondaFan81]

Situation:
Installing H23 intake manifold onto F22A1 w/11:1 comp. ratio NA build-up.

1) Is H23 throttle body 60 or 62mm?

2) Which AEM CAI you suggest, 2.75" (92-96 prelude) or 3" (97+ prelude) for my application?

3) What is stock F22 throttle body size?

thanks

Found answers to some of my questions here...just filling you all in.

1) H23 inner diameter of TB is 60mm

2) 60mm (H23 TB) = 2.36 in
AEM 2.75" = 35.5%
AEM 3" = 61 %

The % above represents how much larger the cross-sect area of the AEM intake piping is than the H23 TB bore.

I would think that the 3" is larger than I need & you can only fit so much air at a time. Too big, and you'll loose air flow velocity.
