Braided line question

[BHDave]

Hi guys,

I'm going to be installing a braided oil line and probably water lines on a stock rb25 turbo (high flow) as i have now got a high mount manifold that moves the position of the turbo significantly.

I'm wondering if anyone else here has installed braided lines to the stock turbo and if you had to install some sort of restricter on the oil line or whether it isn't really necessary. I've seen both on redtop SR20 turbo swaps and neither of them blow smoke so i'm left wondering if it's needed on an rb turbo.

Thanks

Dave

the std turbo is ball bearing so yes you need a restrictor for the oil feed

dont they have an internal restrictor?

all BB turbo's ive seen have an internal restrictor on the cartrdige itself

no idea, thats why i'm asking. apparently there is one in the stock oil feed line but that will be going.

Standard turbos have a restricted banjo fitting on the block side. Just re-use that banjo and your restrictor is there.

It helps to look at what you have first.

Both of the stock banjo bolts have a restrictor too so now i dont need to find one

That makes a total of 3 factory restrictors between the block and the turbo, i guess Nissan were trying to get it spot on.
