I've recently found out that my MY05 WRX PPP Wagon is down on power due to a previous owner changing the wastegate hoses and forgetting about the restrictor pill.

Surely someone on here knows the correct inner dianeter of the pill installed by Prodrive/Subaru?

For now I have a 1.2mm installed, although I would imagine Prodrive would have reduced the hole to achieve more boost?

Cheers

JDM,

I've already been on that thread and it doesn't specify for my exact model with the PPP, like I said, I am running a 1.2mm as is specified in that thread.

What I need to find out is whether this was changed by Prodrive as seems to be the case for many models.

 

I see.
