Plastic manifold intake diameter

[Nvy]

Hey guys,
Id greatly appreciate any input on this. Im looking to upgrade the TB diameter but first wanted to find the inlet diameter of the manifold so ill know what to look for. My idea is to fit a bigger TB together with an adapter that will serve as a spacer too. If i get the CAD for one adapter that fits more of these can be created so its a win/win for all of us

Cheers

Moving with this, I have a meeting with somebody who can make an adapter. Anybody has an intake manifold sitting around to do some measurements? Need the ID and the OD of the intake manifold.

Also would anybody be interested in an adapter to fit the whole 2zz intake to 1zz so I can discuss this too?
