Nope the throttle bodies change throughout the years . I have 4, i have seen 3 and 2...

Looks like there should be a third vacuum hose according to this:

And I could swear I have 4 on mine.

Late 2g's only had two nipples on the throttle body. My brother's stock one ('99) only had two.

Ok, just checking, cause i've been having idle surge problems and wanted to make sure that wasn't causing it. Thanks

JDM throttle bodies have one nipple, at least all of the ones I've seen or heard of.

Yeah that's exactly like mine, only one port on it has a nipple, and on mine it is vacuum capped off (no emissions)

Yep, I have one of these on my car (as will my brother) and we pulled out that nipple and had the hole welded shut
