Joey, can you measure the original WG port diameter for our reference. I forgot to measure mine.

Sounds good.
That's what I ported mine to: 27x28mm (see previous post)
I think 2.5mm overlap should suffice.
I ended up with 2mm minimum overlap on the side closest to turbine
So,
Original WG port diameter = 24.75mm, Area = 3.14*(12.4mm)^2 = 481mm^2
Enlarged WG port diameter = 27x28mm, Area = 3.14*(13.5mm)*(14mm) = 594mm^2
Total enlargement = 594 - 481 = 113mm^2
Percent larger = 113/481 = 23% larger than stock
Wastegate flow will not improve by 23% however, there are many other factors involved in gas flow through orifices that are very difficult to quantify. Scientific BS aside, bottomline the larger port will flow more than the smaller original port!
Here's some more pics. Hope this helps
