Changed thread title from "Easy Question" to what information that you are trying to obtain. Please make sure that you do so in the future so that members know what you are looking for and it also helps with the search function as posting "Generic" type titles such as "Easy Question" do not work with the search function.
Now as far as your question goes.
Are you referring to the flange that bolts to the engine, or the flange that bolts to the exhaust?
The flange that bolts to the exhaust is bigger than what is used on our cars.
Why are you asking the question? What are you attempting here?

So then how do you position the turbo farther from the manifold so it can clear the intake? i know i have to make the extension custom, but i thought there was a flange i could buy for the custom job. so everything to attach from manifold to turbo to clear the intake has to be custom even the flanges, correct?

I'm assuming he's putting a turbo on an NA engine, which requires a spacer to clear the intake. How much you have to space it out depends on which intake manifold you're using. Look at Aaron Cake's website for details about how to do the spacer, but it's pretty straightforward. Basically you're just taking two engine flanges and welding some pipe between them. It goes between the engine and the stock manifold.
It's worth noting that in an FB you're going to run into the idler arm pretty quick, so you may have to get creative. With my Weber sidedraft intake manifold and S5 turbo and exhaust manifold, there's just enough space that with some clearancing of the turbine housing and one of the intake runners, I can get away with just a 1/4" spacer and an extra gasket between the manifold and turbo. I am concerned about heat with this setup, but with some insulation between the turbo and intake it might be okay.
