Alright so Comparing these housings. They are both supposed to be from S4 TII but look at the exhaust. I have 4 housings (2 sets of 2) They are both supposed to be stock but I don't know... I compared both sets to each other and look at the difference in the size of the exhaust ports. The one on the left if larger. Is it from a different series engine or is it an N/A (but I don't see a diffuser)?

 

looks like one is ported and one is not.

 

there both turbo you can tell ther not na because na housing have diffuser plates in the exhaust. it almost looks like the one on the right is small in actually width of the housing. maybe a 12a housing i dont know never had any experience with those. where did you get them from?

 

the left one seams closer to the camera to me.

 

+1

 

The right one is dirtier, and the left one is cleaner?

UR right it was a bit ditrier and closer to the camera. LOL But the exhaust port is bigger. The one on the right is definately a S4 TII housing, it is off the JDM engine I bought. the other I just got. There are some number on the top of the housing that are not present on my JDM one. Weird like a vin or something. Maybe it is a reman housing. I'll post a pic of how the whole thing looks tomorrow and the numbers on the top. Weird though cuz it is really pretty clean and looks like it is from a reman engine...

 

Take some pics of the exhaust port from the other side, and we can get a better idea.

Plus, can you take a pic of the "hole" that would appear just a little higher in the first pic?
FC turbo rotor housings have coolant passages right above the exhaust port...

Alright here are the pics as requested... The first two pics are of the larger one...

 

first one is definitely lightly streetported, second one is definitely stock. You can see that the second one has the 1mm bevel all around the port, while the first one comes to a sharper edge.

 

Makes sense. LOL Thanks so much for the help...
