A buddy and I are having an argument over this. Do you use an O2 housing with an external wastegate like a tial? Or can you port them if you do keep the O2 housing?

DGajre777 said:You can't delete the o2 housing. The o2 housing is for the turbine outlet and the wastegate outlet. If you run an external on the exhaust manifold, you have to weld the wastegate port of your turbo shut. You will still need an o2 housing for the turbine outlet.
The best way would be to get a SBR manifold with the Tail 38mm flange, get a Tail 38mm flange, weld the wastegate shut on your turbo and then get a regular o2 housing. - This would be a manifold mounted external wastegate external dump setup (unless you reroute it).
The other way would be to get a regular 2G manifold and get an o2 housing that has a mount for a Tail 38mm wastegate. www.122performance.com, www.victoryperformance.com and www.straightlinespecialties.com sells these o2 housings. - This would be a o2 mounted external wastegate external dump or rerouted o2 setup depending on which o2 housing you buy.
Sorry to bring this back from the dead but this would be the best place to get my question answered. I had a very similar question to the original poster:
So if I was running an ext wastegate on my manifold but had a regular o2 housing this wouldn't hurt my exhaust flow? The reason I ask is because although your wastegate flapper will be welded shut, the rerouted part of the o2 housing will leave a hole open in the way of the main turbine exhaust flow. I was wondering if the gases coming out of the turbine will just pass by this hole or will it cause a turbulence? I hope my question makes sense, if not Ill try to clarify. Any help would be appreciated. thanks
Yea true it can be done but I don't want to mess with it! It looks so sexy the way it is and I rather not hack up such a beautiful piece. How bad will it be if I just kept the recirculated o2 the way it is?I had an o2 dump on my car and when I switched to an external gate off the manifold I cut off the dump and welded that hole shut. This is going to be harder with a regular recirculated o2 housing but can be done.
unfortunately....so am I. I called up Punishment Racing and they said they'd replicate that piece but w/o the recirculated part.I don't think you would notice a difference. But I am all about making the parts of my car work perfectly with eachother.
