Hey guys, Can someone shed some light as the where the compressor nipple outlet is on a OEM SE motor..... cant see it from engine bay or from underneath....
Where else can u install a MBC if not between the wastegate and the compressor housing?
pics would be fantastic but seriously having trouble finding it.

Re: SE - MBC install
See http://www.mazda-speed.com/forum2/index.php/topic,567.0.html
The hose labelled 4 is the Throttle Body elbow, it has 3 additional connections:
1. AIT2 socket (on the left in the picture)
2. BOV barb (connects to BOV, labelled 6 in the picture)
3. Boost Controller Barb (above the BOV barb in the picture - this connects to the Boost Control Solenoid, labelled 5 in the picture).
ie. "the compressor nipple outlet" you refer to is #3 above (it's not on the the turbo)
Flyin' Miata's Throttle Body Elbow doesn't have this barb on it, instead their Little Enchilada kit comes with a pipe between the turbo and intercooler that has this barb on it.
If you haven't done so already, join the US mazda-speed.com forum and check it out, it's specific to MSM/SEs and you'll find lots of good info there (including lots of MBC installations) - they can always use more Aussies too!
Also, click on the "LINK" text on this page: http://www.mazda-speed.com/forum2/index.php/topic,27852.0.html to see all the MAZDA technical documentation for MSMs (in PDF format).

Re: SE - MBC install
Ahh lovely.
So if i insert it in between the waste gate and then line that runs to the Throttle body inlet pipe that would be correct?

Re: SE - MBC install
I have put on a TBI metal pipe instead of the stock rubber one so i don't have that outlet on the TBI anymore.
My intake pipe doesn't have anywhere else to connect the MBC to.
Can i just put it between the waste gate and the blow off valve vacuum line as seen in the video posted in post#2?

Re: SE - MBC install
The hose from the rear of the intake manifold to the BOV is the BOV actuator that allows incoming air to be dumped back into the intake when you take your foot off the accelerator - the butterfly valve in the intake manifold inlet closes causing a drop in manifold pressure and opening the BOV's outlet.
The MBC's pressure inlet MUST be BEFORE the intake manifold's butterfly valve since that's the boost pressure you're interested in controlling, NOT what leaves the manifold.
I strongly suggest reading this thread for additional information: http://www.miataturbo.net/diy-turbo-discussion-14/boost-sag-no-you-dont-need-ebc-47532/
