What oil line pressure does this turbo use?? What size restrictor is best considering I am using crank oil jet mods so the pressure is lower than normal.

Or the size of pipework.

Basically I need to make an adapter to fit over the oil gallery, but will be 1/4inch pipe then tig a restrictor on the end to screw the oil feed on.
Make sense?????

 

this is what im running in my t04s

-3AN fittings and pipe. thats just right.

 

Here is the answer I received from cheapturbo. My TO4R comes from them:

If its the standard bearing we still do not advise to run a oil restrictor we don't run them if you have a good oil return and a standard -4 line you will be fine

 

I would not run this on a standard bearing turbo you will starve it of oil, I would run a -4 line and -10 return.

 

im going to be running a t78 with a -4 feed and -10 return... do i need a restrictor?

No

 

What about a GT40R, what size feed and do I need a restrictor?

-Silvio

 

What inner Diameter pipe is -4 and -10??

 

i have over 9k miles on my turbo with that restrctor, no shaftplay to date

 

-4 is equal to .25" -10 is equal to .625" the smallest diameter recommended for the drain .5" you can run .5" with no issues at all but it has to be a smooth bend, no kinks.

 

ok thanks

 

no oil restrictor here on my t04r

 

I am running atkins oil jets mods so the pressure is going to be lower than a normal FD
