External Wastegate Flange

[A Grave Digger]

Hey guys.

Bit of a noob problem here.

I brought a OBX RB20/25 manifold second hand and it doesn't have a flange for the external wastegate on it.

I have measured the diameter of the wastegate pipe (unsure if thats the right name) and it is 50mm.

Therefore will I be able to use a 50mm flange and weld it onto there?

I know it sounds pretty simple but I just wanted to check before I went a brought a wastegate and flange that was too big.

thanks very much for your help.

It was most likely left off intentionally, most good quality wastegates will come with their own flange when you buy them.
