My post got removed by the /wrxsti mods and someone told me to post here instead. Does anyone have the IAG Air oil separator on their STi with a frontmounted intercooler? I asked IAG and they said it was possible, I just wanted to know how feasible it was and if you need anything extra for the install.

I bought a 2016 STi a few months ago and it has been a great car. It has Cobb Stage 2 supporting mods and tune. Got it for $25k after tax, tag and title and it only had around 45k miles. The first thing to fail was the A/C compressor. Tried changing the clutch pulley but it is definitely the compressor as it burned out the new clutch pulley within 2 days. Wasn't too miffed about it because it's a 11 year old car. So all was well for a while. Then I noticed some smoke on start up out of the exhaust. The smoke smelled like burnt oil so I looked into it and figured it was the PCV valve. I replaced that and figured all was well. It makes about 19 psi of boost when everythings working. Well, the other day i noticed it was only making about 17psi max. I wasn't getting any crazy knock readings on the AccessPort yet and my DAM was fine. Then it devolved into only letting me build about 10psi and I was getting pretty bad knock readings (-4.2 sometimes -8.4) and my DAM would drop to 0.000. There was a time when I could do a pull from 2k rpms to like 4k and my DAM would go back to 1.000, but it won't even do that now. So I did a boost leak check from the turbo inlet pipe, plugging up all the various nipples on the inlet pipe. It didnt seem like there was a leak, so I put everything back together and took it for a drive. Don't think I did it quite right because I could only build about 13.2 psi. Also, my AF correction has been going crazy this whole time from -25 to 25. But after this test my voltage started going crazy too, dropping to like 10v to 20v. The test drive also revealed my dash lights randomly flashing; I'm guessing from the spike in volts. I tested the grounding on the alternator and it was around 0.01v and the main terminal was around 14.5v and it sustained that under a little blip in the throttle. pl0x halp
