I need to talk to someone at Garrett, but their website only provides links to dealers. I contacted ATP about restrictor placement, and their information conflicts with the information provided on the website.

I have -3an line. The restrictor I bought is a male-female 1/8" NPT .035" fitting that I recently found out won't fit my GT3076R turbo.

Taken from Garrett's website:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040" diameter orifice upstream of the oil inlet on the turbocharger center section.</TD></TR></TABLE>

Garrett says it should be upstream - ATP told me directly on the turbo itself
Garrett says a minimum of .040" - ATP sells .035"

I really need to contact someone at Garrett who knows what they're talking about. This conflicting information makes me really uncomfortable.

Well technically, on the inlet of the turbo is upstream, since the fitting is before the oil enters the center section. As far as the .035 vs. .040 fitting... garrett makes em, ATP is one of their big distributers and I'm sure they're not out to wreck your turbo, but it shouldnt be too hard to get a .040 drill and bore it out.

As far as I know, those fittings are made by or for ATP, and not by Garrett. You're right about the fitting being upstream, but I'd like to put it farther upstream.
