They are separated because one hole is the wastegate and the other is the turbine outlet.


The factory O2 housing isn't sealed from one another. The divider is notched out.

I bought a megan housing for my car and it didnt fit. I bought a megan header for my da integra it didnt fit and had the worste pipe junctions.

I ordered both parts the same day, they are 0-2 with me. They make garbage, even a blind man hits the mark once and awhile.

I would say try and get someone to run a bead(weld it) around the inner without distoring the flange. That area might, over time create a hot spot because the exhaust gasses will get trapped. Kinda like heating up something with a blow torch.

Good luck

I can't see it being any different than stock.

Is the merge point (where the WG section meets up with the turbine gases) ported or is it a round hole?

well i noticed a cpl of things from other o2 housing, the oem one seem to not be fully divided between ports, and the works o2 housing seems to have only one port instead of two, sooo i am thinking at this point that it would not hurt me performance wise

that porting job looks sweet, but its from the bottom, the part i am talking about is where the flange seats between the ports

I've ran the megan piece a year ago and it caused a lot of boost creep, I even had the merge hole ported to try to alleviate the problem, after that didnt work I took it off and threw it in the trash that was the best solution to the problem. I bolted on a Titek V2 O2 right afterwards and guess what the problem was gone. The Titek is a very good piece and worked out great for what I wanted powerwise at the time. My mods have since changed though, FYI I had a Megan turboback that suffered from cracked welds with less then 10k miles on it Megan is 0-2 with me.

this is some good info as I was just about to purchase a megan 02. I might just wait and save up for a titek v2 then. Any issues with 02 readings since everyone is saying the bung is on the wrong side on the titek?

check the SOCALEVO.NET forums for Looney Tunings data on the megan, invidia and titek o2 housings it's very informative, their are quite a few other threads with charts also on SOCALEVO.NET showing that the megan is inferior, no offense to EVOM members but in general their are a lot of shade tree mechanics and tuners who are cheap on here that go for the typical megan, and ebay/ ams copy intercoolers, and if you say anything negative about those parts all hell breaks loose lol!

I never had a problem with the O2 placement on the Titek I had, in fact the placement on the O2 sensor in the housing shouldnt hardly have any affect on readings, It's the Invidia that people have issues with since the O2 bung is placed low on the housing and the wire management on the O2 needs to be cut away or trimed and re routed to stretch down far enough for the O2 to plug in.

Thanks, I will check that out. Socalevo forum seems to have alot more useful info on there than the Norcalevo forum,.
