Opinions on this 02 housing

[dsmputz]

Hey guys, I was looking through ebay and found this o2 housing. What do you guys think of it?. Being kinda new to the turbo system I haven't seen this around much and was wondering if it's a good setup. I personally would never buy this from ssauto but I WOULD make a couple myself at work. I was kinda sketchy about that little piece of flex pipe in there but if you guys know that it's a proven design i'll go ahead and make some.
thanks again

The flex throws me off quite a bit. But otherwise it looks ok.

Looks like it's made for a V-band DP though. So if you could throw a flange on there it's going to be decent.

Hell, if you could make it go for it. Personally though i'd rather go for a manifold mounted Ext. WG rather than an o2 mounted one.

The O2 housing wastegate never made sense to me, but I've been running an XS Power O2 housing for almost a year with no problems. So I wouldn't worry about the quality, I just question the WG placement.

Yeah, there will be a flange welded on instead of that "v" clamp. I am a fan of the o2 housing wastegate. To me it makes more sense to take exhaust from all four cylinders evenly, plus the manifold mounted ones always seem to get in the way of cooling fans and such. But then again I am fairly new so correct me if i'm wrong.

You get better Exhaust bypass (which is the idea) when mounting it at the manifold as opposed to making the exhaust go through the manifold, through the turbine housing, and then through the O2 passages. You get a quicker release and less chance of boost creep.

Yes they may be harder to mount, but if you pick up a good system it shouldn't be a big deal.

It doesn't eliminate the problem with the stock system and that's the crappy internal wastegate passage. Not to mention that must kill turbine flow to have air being able to circulate all through the wastegate discharge area of the housing even when the gate isn't open. I think its just ghetto. Manifold mount is the way to go, and yes you're right, all cylinders is better, so try to find a manifold that incorporates that.

Well a O2 mounted WG can't be all that bad, FP thinks its a good enough "idea" to setup their FP30 series turbos with that style. Im no expert on this subject but here are my thoughts. Like dsmputz said the O2 mount helps with fan clearance issues and helps keeing things a little more "stock" looking. It will take equal exhaust flow instead of all from one cylinder. It won't create anymore turbulance then a Mani mounted WG as the dsm style bolt on housing will still have the same inlet for the WG passage just a flapper will be welded sht on one, now if we were talkin a different style turbine housing then this could be a factor.

You may want to rethink your statement. If you look inside the turbine housing you will notice that the o2 passage comes before the turbine wheel. In other words the exhaust flows by the o2 passage before it comes in contact with the turbine wheel!!

So are you saying that a hacked up, rusted, welded external wastegate on the manifold looks better than an FP 30 series turbo setup? I also believe that a wastegate on the o2 housing will be stronger than on the manifold. Reason being is do a search of the agp turbo kits, and you will find multiple horror stories of the wastegate tube breaking off from the manifold.

I'm not going to rethink anything because i didn't say anything about the turbine wheel. I said it enters the turbine HOUSING. Which is a true statement.

I'd hope i knew how my WG system worked considering i just ported out my 14b for BETTER WG FLOW.

Also, it's been proven on here time and again that manny mounted WG's will creep less.

But really it's peas and carrots. Run what you want, and run what you think is best. I honestly don't think any piping on a manny will "fall off" if it's built right. Thats the same as saying the welds on the runners will break on a cheap manny. Of course they will, but on a good system you don't need to worry.

Regardless, most people on here wouldn't run a tubular header anyway that they'd need to worry about a WG tube. Most people run the SBR (or similar) style cast manifold, flanged for an external.

Of course it looks fine. I was refering to the functionality.

Wow, Thanks for posting this link up, I have been searching for sometime now for a 3" o2 housing. I have my gate mounted on a SBR manny, So i would just cut that one off the 3" o2 and have it closed up... I'm looking for more top end out of my turbo and think my Evo 2.5 is holding me back, this should be the cure!!!


Thanks once again for the post.
