Anyone know the size of the stock 1.8T throttle body? Also, how big is too big?

I think I'll invest in a differential pressure gauge....
Dwyer makes a nice one, I think they're around $60. It would be nice to try it around the MAF and IC as well

It's a 1.75" outlet, the IC pipes are stock (for now)
I don't think the turbo outlet is that big of a deal, since it immediately expands once it hits the IC piping. once it expands, it's better to keep it at that size rather than contstrict it down again.
I'll probably start with a small one (55mm or 60mm) then maybe do some dyno pulls with different sizes and see what happens.
You have to remember the reason I'm doing this is because I need to use a Ford style TPS, and it's easier to swap in a different TB than try and adapt the stock one.
