Restrictor Pills?
Whats the deal with the restrictor pills? From all I can gather is that a couple of the vaccuum lines have these "pills" in them. Can someone please enlighten me and tell me which lines have the pills before I do this hose job and replace all the hoses with Silicon "pillless" hoses...

Pre-control and wastegate actuators. They're labeled in this diagram (from stickys)......

The pill is just a small metal pellet with a hole drilled trough it. They can be removed from the factory hose and inserted into your new silicone lines. As Sgtblue has indicated they are in the two lines that come off the primary turbo compressor housing.

Sweet thanks guys.... I know what im doing now....

Don't mix them up when you do the hose job. The holes in the pills are not them same size.
|
Also...my stock '93 didn't have any pills in the lines, they were built into the turbos. So if you don't find any pills in the lines, don't freak out....they are likely built in.

Bajaman - Not positive, but I don't think "stock" '93 ever had pills built into the turbo?
Also, RR93 - Make sure you understand what is in your car before you start. If the car has been previously modified, the pills may have been removed or redrilled. If this were the case, do not put stock pills back in the system! |

So I have a random question - where can you buy boost/vacuum pills? I've searched various online stores but had no luck finding any...

I bought mine from a forum member, but I have also heard you can buy comparable sizes in carburetor jets, which summit racing has....
Wastegate (shorter hose TOP) - 0.064in (Drill # 52) Precontrol (longer hose BOTTOM) - 0.059in (Drill # 53) http://www.summitracing.com/search/?...=HLY-122&dds=1 |

I understand that for single turbos, they also need restrictor pills. How and where do I get them and how do I install it?

What you are asking about is installed in the oil feed line(line from top driver side of block to turbo oil feed). Rx7store sells a line and restrictor that should work for you setup, if you are running a 67mm or smaller journal bearing turbo you likely will not need one. |
Wow this thread blew up since I left, lots of good info. Im pretty sure That the lines in my car are all stock so if i have the pills in the two lines pictured i will replace them into the new silicone lines. If not than no need to worry... Thanks peoples....

Bringing an old thread back from the dead to add some pictures because it's one of the first search results on this topic.
The two lines coming off of the front Turbo have the pills in them. This is from a 93 FD. https://cimg4.ibsrv.net/gimg/www.rx7...07b1076625.jpg https://cimg6.ibsrv.net/gimg/www.rx7...476a7a9271.jpg https://cimg8.ibsrv.net/gimg/www.rx7...a866ba225c.jpg |
