View Full Version : s-14 oil feed.. is there a oil line restrictor..

since the turbo is a bb turbo.. does nissan utilize an oil line restrictor to reduce the pressure going to the ball bearing center section..

i was just wondering cause we installed a s-14 turbo onto my brothers s-13.. and i dont want it to blow prematurely.. just wondering about the oil pressure?

diff bango bolt? something?

I know of a few places that will make up a restrictor(AGP turbo, talk to Ben tell them Pete sent u!) for you if you are using this on a non-sr engine. This does however bring up a good point: The lines themselves are nearly identical(i know bent different) s13 to s14 to s15, so my guess is that the restrictor is in the block or just less pressure is allowed through the lines, with no restictor. I konw that for the PE kits and HKS bb turbo kits they do infact come with a restictor. It may be that the factory ball bearing turbo's arent DUAL ball bearing as many after market turbos are NOT. I know my HKS and my friends PE are.
