What's the difference between a 1g nonturbo throttlebody and a 1g turbo throttlebody?

[-DSM2NR-]

The guy who owned the car before me put a 60mm 1g nonturbo tb on it . I've installed some hard pipes and now the rubber keeps blowing off since there is no tb elbow at all. And I can't even put a tb elbow on that kind of a tb even if I could since the nonturbo tb isn't flat as the turbo version is.

Now the question is: are there any other differenced between the 1g turbo tb and the 1g nonturbo tb (different connectors, positions of the nipples etc)?

Thanks in advance

The non-turbo TB doesn't have the 4th nipple on the back, as well as the obvious lack of a TB elbow. I have made a turbo 1g TB fit on a NT 1g, that was pretty easy(just blocked off the nipples), but making the new intake pipe wasn't fun.

The N/T throttle body also is not built for boost.

what is the 4th nipple there for anyways. Will it make any difference if it's disconnected?

and you said that the 1g nt tb is not built for boost? what exactly do you mean by that? I don't seem to have any problems with mine.
