Going to be running a turbonetics t3/t4 turbo
Do I need to run a oil restrictor for the feed line and if i do which do I use and where can I get one. Thanks.

 

for a <20 i would
atpturbo.com

or people found that mccmaster carr has a .60 fitting
that is the same

 

If your running a -3 u don't need a restrictor

if running a -4 u need to run a .060 restrictor.

 

please don't just slap an oil resistrictor in the oil line. You need to check the oil pressure at the turbo.. then deside if you need a restrictor. Turbos like to have around 15-20 psi at idle and if you can keep it to 35-40 psi at WOT it will help with your spool. You should never have over 50 psi of oil pressure at the turbo. That much can blow oil past the seals.

Wonderful advice indeed...

 

Thanks for the help im going to use the pressure gauge to see were its at.

 

ive found a lot of the vtec cars spinning 8000-9000rpms will have well over 75 psi oil in the system.


id get a restrictor regardless, theres no way that the pressure in your feed line is gonna be half that of the motor, and it will save your seals some trouble

In the oil system and AT the turbo are two different things.

 

there is an easy solution to, place a t fitting with a mechanical pressure gauge at the turo oil feed inlet and see what kind of pressure you are seeing at the chra itself.

also,just becasue you are using a -3 line dosent mean you dont need a restrictor.

 

We run -3 line, and no restrictor on every turbo we run with no problems....

 

i thought that the -3an had more pressure than the -4an, therefor need to be resticted ever before the -4an would. anybody have any thoughts on that.

You have no problem with -3 line with both BB and non BB turbos?

 

Correct....No matter what everyone has there own opionion so even though i say dont run a restrictor some will say to run them...

Thanks for the info, im just going to run a gauge on it just to be on the safe side and know for sure were the pressure its at. Cuz I have already lost my first turbo due to the seals blowing out.
