Hopefully Chris will have an answer.

Mike I'm suprised your not going with bored out 748R throttle bodies with Shower injectors, I know as standard thet restrict down to about 44/45mm but the butterflies are 54mm.
The Pico injectors you can use with them can flow a lot more fuel than the older injectors which results in pulse length times that can be shorter than the time taken for one revolution of the engine, which to me would be the way to go

On Chris's website it refers to "throttle bodies machined to remove the restriction"
