    The restrictor pill would be in one of the vacuum lines connected to the turbo. If you say it did not come with hoses then you are going to have to find one. Here is a pic I found a long time ago that helped me in my quest to put my wasregate solenoid vacuum path back to stock:

    I assume you are going to use a COBB map correct? If so then there is a tutorial somewhere on their website that describes the whole process of drilling out your restrictor pill diameter. I am looking at a tutorial for a 2006 WRX MT with a VF39 and COBB says .043" +/- .001" (a #57 drill bit).

    I dont think you have to drill the pill on pre 06 setups...should just use the one from the vf-39 if I recall.

    I looked at cobbs note on the vf39 swap into the MY03, and it says nothing about drilling the pill?

    Why dont you actually have the mechanic who is working on the car read up on the install.

    On pre 06's you dont drill anything. You need to figure out if you keep your stock TD04 pill or the vf39 pill.

    I THINK you keep the 39 pill from memory but I am not 100% sure.
