Vacuum/pressure flow restrictor pill ???
Ok, so I've got this '90 Turbo II, and I'm replacing bad vacuum hoses. I have the air pump off do I can get to them. Everything is stock Mazda except for the air cleaner and Street Port by Rotary Performance in Garland TX. I've replaced a few hoses already, and I tug on the one from the output of the turbo to ?? small steel line. It crumbles - it's toast. This is a REAL SHORT rubber hose, about 4 inches long. The gap it spans is only about 1 inch. INSIDE this crumbly hose is a small brass pill with a small hole in it. I almost didn't find it, except that I had to get a serrated steak knife to cut off the remaining hose bits. What is this little thing called? Is it supposed to be there? Should I clean it up and put it in the new hose? ![Confused](https://www.rx7club.com/images/smilies/confused.gif)
Thanks,

Are you talking about an oil or coolant line to/from the turbo, or a vacuum hose? The only vacuum connections on a stock S5 turbocharger would be the line from the compressor housing to the wastegate actuator and the line tee'd in for the turbo duty solenoid (boost controller).
Do you have a picture? The only restrictor pill I know of on a stock car is in the hose to the boost sensor, which is on the strut tower.

the wastegate acutator hose has a restrictor in it as well. Is that what you are referring to? It goes from the turbo to a metal line, to the diaphram for the wastegate actuator

Right, it's a vacuum/pressure hose from the turbo output to the wastegate actuator. I found the hose in the diagrams and illustrations in the factory maint. manual, finally. But I haven't found any ref. to a restrictor in the line. Smoothing out or slowing down the signal makes sense. Is this a standard Mazda part, or something the gurus at Rotary Performance added when they did the rebuild?

Bump,
I just replaced my ancient wastegate hose on the stock turbo as it was cracked and full of rust inside. I found there was a restrictor pill in the old hose. I left it out when I replaced the hose.
I want to know if I need to stuff that pill back in my new wastegate line.
Thanks,
