Keep on blowing thrust plates!

Here are the replies ive received so far.


Hi Chad,

Garrett has a great article on the Turbo By Garrett web site that addresses this question and a host of other installation questions that often come up:

TurboByGarrett.com - Turbo System Optimization

I hope this information is helpful!

Thank you,
Patrick

Hello,

I would not use a restrictor with a journal bearing turbo, use a -4 feed line and you should be good to go!

I WOULD START BY JUST USING A -3 FEED LINE.IF YOU GO TO SMALL AT FIRST THE TURBO WILL FAIL.IF IT LEAKS MOVE DOWN TO A .100 RESTRICTOR.BE SURE YOUR DRAIN IS VERTICAL AND AT LEAST A -12.
THANKS

I agree with everything but what the fellow from Tial claims. While that may be the case with most cars, he's apparently not familiar with DSMs and the amount of oil pressure variance possible.

I agree. Heres another

Chad,

Based on those pressure numbers, you shouldn't need to add a restrictor.

Restricting anymore might cause the pressure at idle to drop to 0.

Wow... my whole engine would be toast if that were the case.

Hi, I have a turbocharger with a T3 journal bearing center section
and I searched Garretts site and it lead me to this email to ask for
tech support if I have a question.

My question is, I am feeding this turbo from my oil filter housing
which as 20 psi idle and 80 psi at 8000 rpm. What size restrictor
should I use to reduce the flow to where it should be?

 

[JusMX141]

"Restricting anymore might cause the pressure at idle to drop to 0."

Not sure if I agree with that statement either. As long as the volume and pressure at idle is there before the restrictor, it will be there after the restrictor too. The restrictor is only in place to prevent an excessive amount of oil being shoved through the turbo at wide-open throttle.

Sorry for bringing this back, but here's a few more pictures of a Kamak rebuild kit. This kit generally seems better than the OEM parts. The oiling hole son the bearings are slightly bigger, the thrust ring has two oiling ports, the thrust collar and thrust ring seem thicker, and the ring is bigger. The seal plate also doesn't look cast, it looks cnc'd. The journal bearings seem to be made of a different material too.
