02 housings

[Bud92gsx]

Can I get pics of a 2g 02 housing please..I think I have one but the ceramic caoting is still not dry so I figured Id ask If someone could post pics of a 2g 02 housing , with the stamped numbers on it if possible..Thanks..

You dont need a pic is the o2 sensor on bottom or top of the housing if its near the top its a 1g the 2gs are down by the flange.

If you post a picture I can tell you.

 

[Bud92gsx]

Well thats the problem I'm not at the garage anymore, so meat I can't post a pic..But I know It's much larger than the 1g, so I know it's not a 1g for sure..

So them what's the difference between the 2g and evo 3..Anybody know what the difference between the two are?

 

[95weclipse]

The evo 3 is hella bigger than the 2g I think its already 2 and 7/8 or maybe bigger

 

[Bud92gsx]

Almost 4 inches bigger is what your trying to say..

 

[95weclipse]

4 inches where did 4 inches come from ? Did you mean almost an inch bigger? and yeah I think it is A ported 2g flows just as good as a stock evo o2 housing.

I thought u meant almost 3 inches bigger..

Not really. I've yet to see anyone port a 1G or 2G o2 housing to flow anywhere near a stock Evo III housing. It's physically not possible without porting the 2G housing so thin you'd grind a hole right through the side of it.

Manifolds are a different story.

Well that setttles it..I've got a 2g 02 housing that I need to swap that In once in ceramic coated.

I stand corrected. I thought I read some where that a ported 2g flows just as good as a stock evo one. sorry my mistake.

One thing to bear in mind with the EVO3 o2 housing, the outlet flange is clocked slightly different than a 1/2G, so if you bolt up your existing DP it'll twist up the flex section and possibly press into the t-case. I've run them that way and it'll usually still fit but something to consider.

 

[Bud92gsx]

Are the stamped numbers the same on the 1g and 2g..Cause i'm back in the garage and i see that the numbers are the same on the one I have on, And the one I want to put on..

 

[95weclipse]

where is the o2 sensor hole located?

You dont need a pic is the o2 sensor on bottom or top of the housing if its near the top its a 1g the 2gs are down by the flange.

Like Ive said before this is the easiest way to tell.

 

[Bud92gsx]

Its at the top by the turbine housing..But it looks bigger than when I took off my stock one..Unless the 13g turbo has a different 02 housing as well..

 

[95weclipse]

they are both 1g. is the one ported maybe? can you post the pics of the two?

 

[Bud92gsx]

I can tonight, but the stamped numbers both match..My stock one is 20 miles away in storage so I can't do that one..I gota get the turbo off anyhow, I broke 2 manifold bolts the long ones..

 

[95weclipse]

Well post pics of the one you have now like the out let and inlet.

Do aftermarket O2 houseings flow better then EvoIII's?

 

[JusMX141]

Some do, but too much o2 flow will lead to incurable boost creep....keep that in mind.
