Hi all,
I seem to be boosting off the wastegate (something like 7-5-7) and read that it likely is caused by missing pills in the pre-control and wastegate lines. I want the extra boost, but I also don't want to go away from the stock parts on the car. I thought I saw it somewhere on the forum at some point, but I can't seem to find the part numbers anymore. Does anyone know where I could get them or does anyone have any they are willing to sell? Thanks!

 

The pills are in the vacuum hoses.

N3A1-13-ZLY

I ordered these back in 2010 when I ran in stock class.

Mazda still has these

 

Only the earlier FDs had pills in the hoses. Because unknowing people would replace the hoses and throw them away, then boost would be messed up.
Thus later years (?) had them built into the 2 metal tubes.

 

I used carburetor jets to replace some of mine. Just match the hole size as close as possible. I don't remember which ones I used.
