I dont think you need a restrictor on a journal bering turbo. thats what inline told me

 

would a GT3076r need an oil restrictor?

 

Well, i already decided to jack up the car onto the stands, drain the oil, do wats necessary to drop the pan again bleh!..

B and T motorsports walking distance from my crib can tap the new location for 20 bucks and weld shut the old hole shut. 65 for the new oil drain kit so this should fix the problem.

I'm wondering where the best place is...

where does the oil level sit on level surfaces? is it right at the top of the oil pan? how many inches below? cuz i was gonna do what other dood did and right above the drain bolt closest to the edge was a choice, but if i have to have it tapped in the Front right of the oil pan i guess there too.. just wondering.

 

A Garrett GT ball bearing center section only needs 20-30 psi to lubricate effectively. Many motors produce oil pressure in excess of 100psi, often forcing oil past the shaft seals, causing smoking problems.


An oil restrictor will drop pressure levels to the appropriate level, alleviating smoking problems and ensure long-lasting, well lubricated bearings.

The s2000 oil pressure is around 80-90 psi but dont qoute me on that. As for the gt turbos some of them have them built in. I had a gt-k 550 ball bearing turbo and It came with one In the box. And from what I hear cars that have stock turbos have them built in aswell.

 

oooh

hmm.. wait.. before i do this to myself... the oil restrictor should probably fix this? i mean the feed line is just a small steel hose with a 90 degree bend into a fitting and its small.. but then again, the hole seems kinda big i suppose...

i tried that site but it didnt work =/

 

Try copy and paste because Its working for me or you can just google it.

 

OOOOHhhh.. i see it.. well my fitting is just like that BUT it doesnt have the small exiting portion! its a pretty big hole in and out so maybe thats the problem?

so heres a question then... i have a 50 trim t3/t4... its not a gt turbo.. so i'm wondering if that makes the difference...

 

Yep. I'm tyring to figure out how to plumb one now, but i'll prob post a separate thread about it.

 

I had a brand new out the box 60-1 garrett non bearing turbo and It smoked as soon as I put it on. so I put a restrictor on It and I have had no issues with It and I have put about 4000 miles on It and it still running great with no smoke.

 

ok... soo... i just took my car to B and T motorsports for them to tell me what they thought... they looked at my lines and said the fitting is too big and the turbo is probably seeing every bit of the 80-90 psi...

my car doesnt smoke at idle, and when i'm cruisin is when you see slight smoke coming out...

they also recommended the restrictor and said to swing by tomorrow and they'll have it and replace it for me right on the spot...

they said that'll do the trick, but they did say however that the oil drain line isnt high enough and COULD be an issue but also said it was wiser and cheaper to change the fitting to a restrictor fitting first... then go from there..

so we'll see!
