Need help identifying this O2 housing

[jabinya]

I bought a O2 housing from a friend and noticed the O2 sensor mounts in a different postion than mine. On my OEM housing the sensor is closer to the flange for the downpipe.
Is this from a 1G or a different turbo?

That goes to a 1g.

I hope he didn't tell you it was a better/larger o2 housing. If he did, get better friends.

No, he didn't say it was from a 2G. It is ported and I have never had any experience with 1Gs so I went ahead and bought it. $20, no big loss. I've got a backup now in case mine cracks.
