Hi!!

I have a garrett ta3405 Ar .63, i would like to know wich oil restrictor should i use? now the turbo oil feed line is installed directly, i know it's bad for the turbo seals too much oil pressure, maybe they're already blown...

Anyway, wich size are you using on your B16 turbo engines??

Now the feed line (interior diameter) it's 4mm or 0.16 Inch.

Thanks!

 

for that cartridge on a -3AN line, no restrictor is needed unless you're running oil pressure over 100psi at idle, and you're over 120psi at WOT. Check with a few other on standard "t3/t4" garrett turbos, they use a similar if not the same cartridge.

 

Could you tell me how many inches are 3AN? wich diameter is 3AN??

At at idle the oil pressure gauge from the oil sandwich (the turbo oil feed line is plugged to the sandwich) is around 85-90 PSI, when cold, and around 90 PSi at WOT

 

-3AN = 3/16" = .1875"
