What flange is this?

[Boomdeeze]

I was told that the Borg s259 I bought has a t4 flange, but I called airwerks and they say that the s259 can't come with a t4 flange but does come in the t3. Does this look like a t3 or t4?

Twin-scroll T4.

We discussed via PM that your S259 has a .84 a/r turbine housing, and I said that I believed someone had a Garrett T4 housing machined for use on that turbo. If that's the case, there's where your T4 housing came from.

Ok thanks, I talked to the guy and he confirmed it was a custom housing housing made for the s259 and it is indeed a divided t4 .84. Thanks Justin, you have been nothing but help.
