I have this O2 housing Im trying to identify. I assumed it was a megan/ebay, but after seeing alot more knock off brands popping up on here Im having a hard time telling a megan from the more generic ones. It looks like its been ported as well and wanted to post up pics of it to see if its worth installing in my new build or just junk it.







It looks like it was ported rather aggresively, but Im not sure if that much will be a problem or not. Thanks.

 

megan's have a tag, but it is megan-like

 

Not always... there are Megan 02 housing without a tag on them, like mine.

OP, that looks identical to the Megan unit I have.

 

Junk it! I ended up replacing my Megan O2 housing. Burned through one of the welds on the inside.

 

did you replace it with another megan or did you get something else?

 

Megan

 

I have used that o2 housing a handful of times, naver had a single problem. I always blend the wastegate port a little more with a carbide burr to get rid of that awful lip that they all come with.

 

I just got my EF3 turbo today. I go to inspect it and when I tried to mount up this O2 housing.....









Luckily I still have my oem O2 housing laying around. I mount that up to compare...








The oem lays perfectly flat, and the megan one has a warped flange.

here is another pic to compare..

 

After a few heat cycles the bolts will pull the megan flange back. Just retorque after the first week of driving and it will be fine
