Default Help with Blouch Dom 1.5XTR oil line

Soon I'll be getting ready to install a Blouch Dom1.5XTR on my 2011 WRX and had a question about the oil line and installation. I've tried contacting Blouch directly via phone and email a few times and haven't gotten an answer yet.

For starters, I bought the turbo used off of a member here, and it did not come with the oil feed line. I ordered a new Blouch WRX Ball Bearing turbo specific oil feed line from Oakos and now I'm seeing on RSD's site that there is also an oil restrictor I seem to be missing.

You can see the restrictor in this pic, it's the silver fitting on the top right:


Do I need this restrictor? This leads me to my next question, how exactly do I install this oil line and where does the restrictor go? The OEM line uses banjo fittings at the top of the turbo and at the back of the block. The Banjo bolt connection at the back of the block looks like it feeds multiple sources. I noticed there is also a compression style connection in the OEM oil feed line, do I disconnect it there and connect the new Blouch oil feed to that?

Any help would be greatly appreciated.

That is not the restrictor, it's the adapter to fit the braided line to the hard arcs line. The restrictor is threaded into the oil feed port on the turbo and is gold in color.

OK, so I have that brass restrictor in the turbo already.

So do I remove the banjo style fitting from the blouch line, thread the adapter into that, and than that gets connected to the compression connection on the OEM oil line?

my 20g xtr has the same setup. i used the 90 degree bend connection to the gold oil AN fitting on the turbo. took the banjo off and used the adapter in line with the factory oil hard line from the block. make sure you use a back up wrench when connecting the adapter to the hardline to prevent twisting the hard line and causing leaks

Awesome, thanks. Now I just need to find the right size adapter and I'm set.

I installed the 90 to the gold connector on top and shaved down the head with my die grinder, to make clearance for the other end. One less place to leak and did not require a large amount of material to be removed.

Does anyone know the size of this line? Is it a -4an? I bought my 1.5xtr used and don't have either the banjo or adapter for the hard line. I'm trying to source the correct banjo for the feed line that was sent with the turbo.

It is -4AN.

ATP makes the adapter which is 12mm female flare to -4AN, you can get it here http://www.atpturbo.com/mm5/merchant...egory_Code=FTG

I found that for my WRX, I had the option to either use the adapter and connect to the existing hard feed line or use the banjo option and connect to the head. I opted for the banjo option since the hardlines are known to crack and leak over time.

A necessary tip if you do decide to use the banjo fitting, make sure that when you tighten the banjo fitting to the -4AN line that the flat face of the banjo matches up with the flat edge of the -4AN line or else the banjo fitting won't seal and it will leak. It happened to me unfortunately
