Do Newage Impreza's run a restricter pill ?
 

Installing a 2nd hand TD05 20 g at the moment onto my 2005 WRX the turbo came without the turbo vacuum pipes.

Like an idiot i sold my old turbo with the vaccum pipe's still attached. so i am going to make some up.

I had a look at my friends 2003 WRX and couldn't feel a restricter pill in the vaccum pipe that come's from the compressor housing on the turbo upto the t piece.

Do i need to fit one ?

If you're running a 2 port BCS then yes, you do need the pill.

Yes i am running a 2 port any idea of what size restricter pill i need. As i say i'm running a Andy Forest 20g on a 2.5

Thanks Liam

You need to discuss that with your mapper, the size of restrictor orifice will depend on the boost range you will be using, he should have a selection of suitable sizes with 1.0/1.1/1.2mm covering most applications.

Andrew...

Your mapper should be able to sort it and should hold a selection.

I Mapped a STi 2002 with a 20G a week or so ago.
The guy's that fitted the turbo through the old pipes out...DOH!

So I fitted my normal 1.0mm and it mentally overboosted.
Then fitted an old pill from a WRX, which I think is 1.2mm and managed to get it nicley under control on the 2-port.
