What size are YOU using for your 676x JB Precision turbo.


GO!

 

-4

 

-3

 

-3 will supply plenty of oil.

 

-3

 

-3

 

-3

All the pte jb billet we bought used -4 all failed,bent shaft,compwheel hitting the housing.

We are very lucky interms of reliability with bw and garrett units.

 

-4 with restrictor and turbo is still truckin along and it's on it's 4th car now

 

I have a -4 and I'm already feeling like its huffing smoke. Bout to step it down.

 

-3 feed, -12 return per PTE

 

Last time I talked to the guys at PTE, they recommended a -4 feed w/o restrictor for the 676X journal bearing turbo. This was back in December so maybe something has changed?

 

PTE said -4 when i blew mine up

 

ihad a -4 no restrictor and started blowing oil. but after about a 2 years but not a lot of passes

 

I just don't know. Seems like im bout to drop it a little. I know the oil pressure in our cars is donkey tough

 

-3 with a restrictor....

 

-3 on one, -3 with restrictor on another

 

you guys are running restrictors on Journal Bearings?

 

I run a -4 because that's what pte recomends. I personally believe I should be running a -3 because with a -4 it started blowing oil out the exhaust. I sent the turbo to precision twice under warranty and they repaired the turbo. It's not blowing out oil anymore but I'm almost positive with a -3 I would've never had to go on that head ache. I think instead of recommending a size hose they should recommend a specific oil pressure

 

i called a few months ago and was told to use a -3 with a -10 return, if it starts to smoke change to a -12...i went with a -12 anyway because the return line is somewhat long

 

I'm not

 

well an update I guess

I changed to a -3 feed and I had a dramatic decrease in smoke on my last outting which was june 1. I actually don't even recall seeing ANY smoke as a matter of fact.

 

Did you use a restrictor as well?

 

-4/-10 for our 6766BB per PTE

 

no

its 1/8npt - 3an on both sides and a -3 line.

 

Same thing I have with my 6765, glad it worked out for you.
