Journal bearing should not need restrictors if oil pressure is in the normal range and if the turbo is properly built. I know that for a fact because I talked to the head guy at PTE themselves and he said. Now a BB turbo will and I got a restrictor for my pte BB turbo from PTE. The guy at Precision said that their journal bearing turbos like alot of oil since they are not water cooled. 4seasons69 just send it in to Precision and have it done right and correct the first time. They are great guys and are willing to explain things and work with you there.

I copied this from another thread it was posted by 95talonracer

so given the fact that i'm in on the low side of what would be considered the normal range I don't really for see oil pressure being the problem

Just want to add to this that the key part of the restrictor thing is where oil is being fed from. If its from the head, its less of an issue. If its from the oil filter housing, its more of an issue. Different cars, different oils, different pressures.

I love stock or stock frame turbos, none of this nonsense :)

This is because the restrictor is built right into the feed at the turbo.

Garrett center sections are meant to be universal, so its up to you to control flow to the turbo.

I completely agree with what you said on that one but my other turbos have been fine. and I just got off the phone with pte and explained my whole setup and the guy said I shouldn't need a restrictor and actually recommened against using one for an scm61
