Confused on T3 o2 Housings

[CleVenger-6]

Im in the process of buying a new 1g dsm. I have been planning the whole build ahead of time. I know I want to go T3 setup with the wastegate on the o2 housing. The turbo im most interested in is the borg warner s256. I looked at it on extremepsi.com and it had a lot of options on size and stuff. I have no idea what o2 housing would work for it, I cant seem to find any t3 o2 housings.

Thanks, but where do I put the external wastegate then?

On the exhaust manifold Almost all T3 flanged exhaust manis come with a flange to put a tial 44mm or something of the like on it.

He's asking where would he reroute the wastegate gases back into the exhaust. With that o2 housing, you wouldn't. You would just dump.

There are some t3 o2 housings on eBay too for $160. I'm using a mitsu flanged one and it's holding up fine. You might need to get the flanges milled down though. Mine were kinda rough.

Are the advantages of a t3 setup worth the extra price, to say if i went dsm housings with s256 and external wastegate? Would it be better for the wastegate to be on the manifold or o2?
