Turbo oil line question
I purchased an oil line kit and when it arrived one of the banjo bolts had a built in retrictor (1.5 mm). I thought his to be odd since the OEM system doesn't appear to have any restriction unless it's built into the pressure line.
The seller claims that this is to "Protect" the turbo. I'm hesitant to limit the flow of oil to my turbo so I figured I would ask to see if anyone here had run into this before?

My stock MCS has banjo bolts for the oil pressure feed line and on the coolant lines. Not sure why your diagram doesn't show them as they were exactly the same on my 08 MCS as well.
As far as the restrictor goes, nobody had much to say about it except that it didn't make any sense to reduce the flow of oil to the turbo. I agree so I used the stock banjo bolts that don't have any restriction.

After blowing out my Garrett bearings, I wouldn't restrict oil flow either --- Garrett doesn't use banjo bolts on oil lines, just coolant.

Oil line
[QUOTE=oldbrokenwind;4255767]OK, I get confused pretty easily --- this thread started out with an oil line kit and a banjo bolt with a built-in restrictor. The RealOEM diagram for my '07MCS shows banjo bolts on the coolant...
Get the proper line from JM turbocoopers. Arric will wrap it with heat shielding and you will be in good shape

Well flash forward a few years and here I am with a completely different Mini dealing with the same old issues. Once again my oil feed kit has arrived with a restrictor built into the banjo bolt. I have installed it but I haven't driven far yet as I'm dealing with all the other fun stuff like thermostat housings, broken exhaust flex joint, leaky oil filter housing, valve carbon, timing chain and ABS. It's easily changed back without any component removal.
So I've been doing some homework on the subject and I have discovered that the restrictor is something that is typically used on ball bearing turbos but not on our stock K03 journal (bushing) type turbos, where oil flow is your friend, to keep the center housing as cool as possible. So there ya go, a good reason to not use that restrictor on a stock Mini but also a good reason why one is used on the ball bearing upgraded units.

It should not have a restriction in the bolt. MINI doesn't use one from the factory https://www.detroittuned.com/dt-turb...ine-super-kit/ .
