I have searched and have not had any luck to this question.

I want to know what would be a proper oil feed setup for a PTE 6262 journal bearing. Head or oil filter housing? Restrictor or no?

Thanks

 

Precision always says no restrictor, but a lot of guys have problems with oil blowing past the seals without one.

 

As per PTE, you should feed from the OFH with a -4 line. The head doesn't provide enough pressure and volume of oil for a JB turbo. However, if your motor is producing upwards of 80psi of oil presssure, I would look into some type of restrictor. Remember, this will be a relatively large restrictor vs a ball bearing turbo.... something along the lines of a .8 or .75 size fitting. Some have said to run a -3 line as another option as well. Its going to be some kind of trial and error. Start with a -4 line. Usually, you can see a little extra smoke out the exhaust with too much oil pressure. If so, try a restrictor or switch to a -3.

 

Thank you for the information.

Right now I am running FP's oil feed line for my journal bearing holset with the .030" restrictor (black unit) which I just read is better for ball bearing turbo's not journal bearing turbo's (probably why there's some smoke)

Anyways, I will try just a -4an with the 6262 and see how that goes. Do you know where I can buy a .75 restrictor?

Thanks

 

Ebay is your friend.

the 6262 chra fittings are the same as garret.

 

Does anyone know what size oil inlet that connect to the turbo from the oil feed line? And if i used the 3an lines, does it fit into both the cars' head and into the turbo? Or do i have to convert both of them to make it fit the 3an lines?

 

I bought a new oil feed line but its 102cm. Can someone tell me if it is a 4an or 3an line? And it comes with* Oil feed T6 Aluminum flange kit with 1mm Restrictor. Its the 1mm a proper size restrictor for my jb pte 6266 turbo? Please help
