^Curious about this too, since this is the tap size (3/8) that BEGI sends.

3/8 NPT then is -6. Does that seem a bit small?

However, the tap is ID and it seems AN is measured OD.

I hate this.

*Edit* I reread the link I gave to anplumbing. 3/8 ID is ~ -8 in flow.

Came to this thread to lambast the OP about his poor grammar in the title. You aren't posting this from your damn cell phone. You have a full keyboard, so use it, you lazy ****.

I use a -3AN feed line with an .035 restrictor and a 5/8" return. On my old journal T25 .48/.49, I ran the same -3AN line with no restrictor.

So by proper grammar, you mean a fine example like this...
"Word to your mother" instead of "Wurd 2 ur mother"
Anyway, what I am getting out of this is that my 3/8" ID hose is the same ID as a -8AN? I have a piece of -6AN laying around, which I measured, and it is 1/4" I.D., so this holds true. So my -4AN oil feed line should be 1/8" I.D. and with my 1/8" O.D. pop rivet restrictor stuck in there, this should mean that my 3/8" I.D. hose should be sufficient in draining my CHRA. The other day I was under my friend's Eclipse GSX looking at stuff, I noticed his drain line (which is stock) appeared to be the same size as mine. His car has "the big 16G" which should require the same oiliing as a SR-20, correct me if I'm wrong.

If 3/8 is good enough for BEGI, it's good enough for me. Only difference is that we are using journal bearing and BEGI uses ball bearing turbos. Not sure if that makes a difference in oil draining though.

One quick question, and its probably a stupid one. Do you guys know when on Begi's website they say line is measured from fitting to fitting, do they include the fittings with the lines?

Perfect thread for my current problem.

New engine same turbo and lines, turbo is over oiled like crazy! -3an feed no restrictor and -10an drain on a gt2871. Old stock engine absolutely no issues with over oiling, new built bpt goes in and turbo is caked in oil wtf? 3estrictor on a -3an line?Never heard of that but I guess that's what I need.

If you look on ATP turbo parts if you are buying the feed connection for a T25 journal its straight through , if you buy the connector for a GT25 i.e ball bearing turbo it has a restriction in. Think this is the same for all Garett journal / ball bearing.
