Greddy Turbo users! BOV flange?

[vspec808]

i'm in the process of buying a greddy turbo kit for my 00 si. I have decided on going with the HKS SSQ BOV, and my question is which flange do i need to buy the aluminum or steel?

this is totally a guess ... but if your charge piping is aluminum, then get aluminum, and the same for steel, since it's easier to weld the same kind of metals together.

this is all in theory, in my head, of course

if i'm wrong, free bump for you!

doesn't the bov come with a flange? Some do, if not then go with the alluminum one.
