Are you sure that's the right question?
We can't answer that because the O2 housing is still bolted to the downpipe!

But if you actually want to know if the O2 housing has been ported for a larger wastegate - it would appear so.

I think that is a 2G O2 housing.

The inner diameter of the downpipe would be the same or larger than the ID of the O2 housing outlet.

I told marc that based on the larger size of the wastgate opening I thought it was either an evo 02 or a modified 02.

Its def. got a bigger than stock wastegate port.

I was under the impression that Evo O2 housing wouldn't bolt on to stock downpipe without modifying the holes in the flange and making them slots. Studs in the Evo housing have larger span.

You are correct. The studs are spaced further apart, they are rotated slightly, and the face is at a different angle. A stock downpipe will NOT fit without modification. I could give you the Mitsu number for the EVO 02 housing tomorrow.

The EVO O2 housing has the O2 sensor in the same position as the 1G O2 housing. The 3rd pic down shows the O2 sensor in the 2G location.

The EVO3 O2 housing is # MR224847.

The 2G O2 housing is # MR188003 (odd that it's off by one number).

Check the part number of the parts next to the O2, and you might find out where the mistake was made.

Or, look up what the MR188004 is. I'd do it, but my PC with CAPS is still down. frown
