Still looking at options...

Can you tell me if a stock RBC will fit straight on our cars? And if i get a bigger throttle boddy does the RBC need to be modified then?

Heres a good RBC - Ported out to 65MM

And heres a another one pre-modified for a k20:

Do I need to avoide the premodified ones? Can you see any advantage paying the extra $100 for the ported RBC if using a stock throttle body?

And lastly will my Icebox fit the RBC or do i need a custom intake?

Thanks guys.
