Wastegate square flange size?

[Ceddy]

I'm been looking at this recirculated dump pipe.

Says its for a 46mm wastegate.
My question is, do all of the square flanged wastegates have the same flange size?
Could I use a 40mm or 50mm?
Also is the distance from the inlet to outlet flange standard?

Also anyone used the stock Porsche wastegate? Any good?

Thanks.

(Please no, "don't buy ebay crap" replys. Thats not what I'm asking.)

Looks to me like a Tial 46mm would work. You would have to measure the flange to make sure but if thats what it says thats my guess.

So, say like a Tial 38 with square flange. The mounting bolt hole would be closer together than a 46?

The Tial 38mm has a 2 bolt flange so it for sure won't work. The tial 46mm is all by itself it looks like

I was trying to use 38mm as an example.

I see what you're saying, only the Tial 46 has a square flange.
The Tial 46 are $400-500 new. Little out of my price range...

Some of the knockoffs have the same style flange, but will say 40mm or 50mm, which I am guessing is plunger size. Was trying to find out if they would work.

You would need measurements for any generics. If you are set on that piece I can get you a good price on a Tial but also as an option have you though about running a punishment-racing recirculate 38mm o2 housing. They are very reasonable and I should have some back in stock very soon. They are $470 for mild steel and you will be done with it. PM me if you want more info.
