Seems BB turbos like 20-35 PSI and most use approx.
a .035 dia restrictor? This sound right, turbo is an HKS
7460.

 

I believe the HKS turbo uses the stock oil line. I would call HKS to see what they recommend. It may be internally restricted, and/or designed to run on the stock feed line.

 

I got turbo almost 6 year ago, but never installed.
It is (was) supplied with it's own oil feed line. No restrictor in it that I could see.

I did call them (thanks for the suggestion) and they claim none needed.
Maybe it is internal to the casing, who knows.................

Reason I brought it up was I saw some talk here and there
about the reduced oil pressure required and found this
for the Garret BB turbos

Been running the HKS for 50k--all good, no oiling issues on line supplied.

 

Good to hear. I had read threads from back in the day
and some said not needed. I didn't get a banjo bolt with
all the supplied hardware (which as you know is virtually
every other piece needed to put in a turbo).

Got me concerned for a bit, as it seems that is
where the restrictor is located, many times, if one
is used.
