Just received my GReddy pop-off valve and mounting bracket and now I'm a little baffled as to where it should be mounted. I envisioned it being welded into one of the intake tubes, but the mounting bracket from RX7.com is a large flat square. Plus it's marked "Mazda/Nissan" so it leads me to believe there must be some good place for it....
Anyway, if anyone could post a pic or two of how and where they have it installed, I'd very much appreciate it!

I have mine mounted just downstream of the IC and with the top of the valve pointed down at the ground. In retrospect, although that position makes a nice clean looking install, it is a pain to reset. I would have preferred to have it mounted horizontally so as to be able to get to the adjustment.
Here's how I did it.
1. Temporarily secure the adapter plate where you want it to wind up. (Double sided foam tape or body trim tape works for me)
2. Mark around the plate with a marker. (If you have a plate that has the 4 mounting holes for bolts mark the centers of the bolt holes also). (Mine wasn't marked Mazda/Nissan so I am not sure we have the same one).
3. Remove the IC to TB pipe (not the elbow)
4. Drill the gas access hole
5. Drill the bolt holes (use the correct size drill bit --remember you are still going to need to tap those holes for the correct size thread)
6. Tap the bolt holes
7. attach the flange with bolts.
8. weld the flange to the pipe doing fillets where needed.
9. install the POV
I have also heard that you can have an aluminum nut of the correct thread size welded directly to the IC to TB pipe and that makes a nice clean install.
Thanks for the replies. So it sounds like there's not really a good place for the big square mounting bracket. I was thinking it would work nicely on the FMIC, but I don't wanna cut any holes in it! May try to rig up something like the link above........
