and you have oil in your intercooler pipes?

Small Frame turbo's can be overoiled and have the seals blown - esp journal bearing ones... the restrictor could work to fix it as is. But a rebuild would also not be a bad idea... I know it sucks that it is a brand new snail; but I would rather take it all off once and fix it for sure; than take it off 30 times trying to cheap out.

exactly

The T04 is a ball bearing turbo and as such should not be seeing oil pressure above about 45psi. A 3rd gen's oil pressure regulator is 80+ psi so the oil inlet line would require a restrictor. Side effects of no restrictor would be as you described.

How should I put a restrictor in the line?

My BNRs have small oil holes and they oiled a bit when they were new .Brian thought they were getting to much pressure so I made a restrictor for each turbo and one for the banjo bolt at the feed line .That fixed the problem .They have been running for 49k miles now on syn oil .They are stage threes super sized .

Rx7 store sells a restrictor and a feed line kit for a very reasonable price last time I checked. You can also use the factory boost restrictor pills if you get creative. I would just buy the kit from rx7store. I have had this problem with larger turbos in the past. There is very little exhaust pressure at idle from the rotary for these big turbos and it common to see oil go shooting out the turbine/exhaust side of the turbo.

With it being a new turbo, Im fairly certain a restrictor will fix the issue for you.

I had to run a restrictor on my brand new turbo to get it to stop smoking...so yeah, it can be a problem. I used the restrictor from RX7store but their line is WAY too long for my needs. I had to use a fitting to get the restrictor to work cause it was too small for my turbo, but it works regardless.

Get a nitrous nozzle and grind it down.

speedjunkie 10-22-2008 03:10 PM

I had tried a nitrous nozzle before, I don't suggest that. Of course, if I'd put alot more work into it, I suppose it could have worked haha. Basically mine got mashed and became useless, allowing oil to blow by anyway.

Kane 10-22-2008 03:14 PM

I use an actual AN fitting as mine; but I was recommending a cheap fix... LOL

speedjunkie 10-22-2008 05:04 PM

Oh I hear ya man. That's what I was going for when I put it in there, but it didn't work for me. I've seen others do it that way, but it didn't work for me when I tried it. I decided to make my AN fitting work.

I drilled an allen set screw and threaded the placement and then I can remove the set screw and redrill for more oil or replace for less oil .How easy is this .

speedjunkie 10-23-2008 04:24 PM

^Damn that's a good idea, I never thought of that haha.

Garfinkles Motor Works 10-24-2008 08:06 AM

No cost and eazy to do plus adjustable .Life is good .
