Hi .
I had pulled my turbo off a few days ago to change all the rubber lines and gaskets . When I had pulled the elbow hose coming from the outlet side of the cold side I had seen a small round metal piece inside the hose . I cut the hose open and it I te same size of the inside of the hose and has a small hole through it . Should this be there ? Should I put it back when I install new lines ?

Will post pics shortly

 

It's a 91 t2 motor btw .

 

if everything else is stock and you were boosting target PSI , Then i'd say yes . in the FD we have similar restrictor pills without it , the car only boosts 7 psi which is the spring setting , with them it restricts the air flow enough that it opens up at the stock 10 psi.

so yes you should probably leave that pill in there unless you have an aftermarket boost controller

 

Well I opened up the turbo not only to change the lines but I was getting a boost leak . it wouldnt hit full boost till almost 5,000 and found that the wast gate flap on the hot side wasn't closing all the way. I fixed it and then found the pill . I was going to run a hall man MBC . It's boosting 10 psi before I took the turbo off with only a HKS F-CON piggy back, Walbro 400, down pipe , intake , full apexi exhaust with cat delete , ect ..

I'm hoping that the wastegate problem is fixed and was hoping to boost up to 12 psi . If I decide to run the boost controller I need to take the pill out ?
What happens without the pill do you know ?

 

It's called a restrictor pill and normally they are only used to smooth out pressure fluctuations. The only place I've seen it used is the line between the intake and the MAP sensor. Never seen one in the wastegate signal line.

I'd remove the pill and just run the hallman boost controller. Stock turbo's have enough issues with boost creep.

Hope you have some replacement injectors if you plan on running anything above 10 psi of boost.

I've run a few stock turbo's without that pill both in the stock configuration and with a boost controller. No issues.
