1g Throttle body elbow vs 2g

So the 1g TB is 60 mm and the 2g is 52, as are the TB elbows.
Are the uicp hoses the same diameter? The 1g looks smaller in pics but I am thinking it is because it flares up to 60 mm.
The bolt pattern is the same though between 1g and 2g right?

Bolt pattern is the same . The hose is not , it does flare at the end . The continuous opening on the 2g is larger .

So on a 1g setup it would be better to port a 2g elbow out to 60 mm instead of using a 1g elbow? Is this correct?
But does that mean the 1g uicp is smaller too?
If so you would have to adapt it to a larger diameter.
If they are different what is the diameter of the 1g uicp?
I saw a faq talking about porting a 2g elbow out to 60 mm but you could only do it in the flange. The outside diameter of the 2g elbow is less than 60 mm.

ok, if you get the 2g elbow, which has a bigger opening at the uicp, but also is bigger throughout, you will need a bigger uicp, something like 2.25" is fine for a basic setup..
