What does the vacuum chamber do? Is it necessary??? https://www.nopistons.com/forums/pub...1047683561.gif

I can't find any info on it...

they store vacuum (and pressure)so that they can slam the turbo actuators open (or closed)

Damn, that nipple broke off when I was replacing my vacuum hoses... I think I managed to drill and tap a new nipple but I was just hoping I could just remove it.

Only if you convert to non sequential.

Otherwise you have to replace it.

Well at least I can get rid of it someday... I beleive I will be going non-sequential soon! must order pfc...

yeah it happened to me when i was replacing my hoses to silicone hoses... i ended up buying a new one...

Where (besides Mazda) can you get one? I've looked around but I haven't found one yet. How much $$$ too. My half ass drill and tap job is holding though. Vacuum is a C. hair from 20"Hg!

I don't know how much money they are but i have 2...the little one that goes in front of the UIM and the one that sits behind the PS bracket. Since I just went non-sequential I don't need them anymore.
