oil feed restrictor for vts turbo

[sliderz]

hi im going to buy the oil feed pipe for my turbo conversion and was wondering how and why you need a restrictor i heard that the flow of oil on a tu is high so what size would i need and how do i work out if its restricting to much (dont want to starve the turbo ) but then again dont want to flood it either the turbo is a t25 water and oil cooled
thanks for any help

I believe the oil is to help lubricate the turbine inside, water used to cool

thanks m8 good to have you onboard i wanna no why i need a restricter axracing has mentioned this in other threads but want more info on it if you know what i mean

Oil lubricate the turbo and in the same way a engine has to have a specific oil pressure to operate correctly as does a turbo. Most T25 are water cooled and the oil is primary there for the bearings. What model T25 is it you have and with what bearings? Depending on the turbo many work ok around 1/16 or 1/32. Try 1/16 and if it burns oil you can always drop down in size.

oil restrictor is to restrtict the flow as the cars pressure is too high and will blow out the seals in the turbo, and the rest ax covered

in a T25 the oil lubricates and cools the turbo. The water cooled side of it can actually be disconnected if you want to (done fairly often on the 200sx oc).

The water is there to cool the oil and stop it coking up inside the turbo and just generally ruining the oil. Allows you to go longer between oil changes, reduces the risk of the oil feeds getting blocked up and helps to cool the turbo once the engine is turned off slightly as thats when alot of damage can happen, once the oil flow has stopped and youve just thrashed the nuts off it without letting it cool before shutting off (cant expect oem turbo cars to all come with turbo timers).
