50 trim oiling on 90 motor

[coltboostin]

Can someone with a 50 trim on their 90 motor tell me where they are pulling their oil feed from, and if you are getting it from the filter housing please be spacific as to which allen nut you removed. I think I am giving my turbo too much oil at its location and with my lack of balance shafts.

a 2mm restrictor does the magic on Garrett turbo. That's what I used to do on my 60-1 Zcar.

Thats cool, bu there's the catch, I just rebuilt my motor, as of right now, their may be 30 miles on it, so it could be the ring just still needing to wear in. I built the motor myself, so maybe I did somethign wrong also . I am not to worried about that option, but /I dont want to put in a restrictor for the turbo and waste it when the oil smoke is from my lack of cylinder wear.

How did you restrict the flow. I'm having the same problem with my car.

I dont know, Im working on that

I tapped inside of a brass fitting that I was using for the oil feed and got me a plug to go in there with a right thread. drill a hole that's 2mm around and drill a hole on the plug. (out of the turbo offcourse) I also went back and shenfer(spell?) the hole for better oil transfer.

I've seen ppl using a carbrator jet too.

Oh, good I dea, well here is where Im at.
found out , at least rre puts their feed in a different spot, check it out.
I P1 P2
(filter) I
I P3


IF you were looking at the filter housing, you would see the filter on your left, and the P stands for the plugs in the housing. I had it taped off, P2, but a random diagram I found floating aroung the internet said P3 is where I sould tap from. I switched it last night, and it seemd to smoke much less, but it the car ran wired last night , so I could not get on it, so we'll see tomarow for the final verdict.

Look about midway down. They have pics and everything for where to tap on the 1990's.

Well, I swiched my oil feed to the one that RRE called for, and NOW MY TURBO IS SHOT. My car gave no pressure to the turbo, and now it has shaft play beyond reason , thats freakin great.

I hate life

The RRE line from the oil filter housing? Did you attach it to the correct port?

How do you know the turbo didn't have oil?

 

[coltboostin]

Yes I even switched my feed to the one they call for!? I know the turbo had no oil b/c when I took the drain off, their was no oil, when I took the feed off, no oil came out, and when I crank the motor with the firring off, no oil comes out?!?!??!?!

I would be worried that the rest of your engine isn't getting enough oil because the oil filter housing should have much more pressure than if you tapped it at the head.

I peg 100psi of oil pressure buddie, that is definatly not the problem, I have to do more digging, but I am to pissed at this point to do anything today.
