What do people do for oil restrictors? I have seen some homeade ones for sale on here before, but I don't know what options are out there. Jegs used to sell some Talvia (sp?) restrictors, but I double checked and they seem to mount in the heads of domestics to restrict oil to rocker arms and will not work for a turbo. Does Aeroquip or any fitting companies make restrictors that are just standard fittings?

Finally, does it matter where the restrictor is placed? Right at the turbo, or right off the feed, or anywhere in between?

Is there a generally accepted size for a restrictor? I remember the homeade ones having a 1/16" orifice.

Thanks!

I'm going to run one of these and drill it out, and have a pressure gauge right behind it.

My 2cents=>You shouldn't need a restrictor for a -3 AN line...

but if you must, don't use a restrictor (it will clog) use a pressure regulator or needle valve so you can adjust it... and put it right before the turbo.

 

well heres some if you need them

two versions

garret ball bearing version - http://www.atpturbo.com/Mercha...e=OIL

garret T version - http://www.atpturbo.com/Mercha...e=OIL

not sure if these will work for you....

but so far these guys got some good stuff...ordered lots of stuff from them in the past few months...

 

Nice, never saw those.

It's for a Greddy turbo with the stock Greddy feed line (I am not sure what size it is).

I would rather be safe than sorry, and the way I see it, it can't hurt having one (just $10 of extra insurance).

That second one looks perfect. I am using a GE block adapter, which has 2 ports - an -8AN port and a 1/8" NPT port. I was thinking about threading this into the 1/8" port, and hooking the feed line to that running to the turbo. I would have to do it that way because the turbo uses that wacky banjo end on the turbo side.

Now I just need to find out if it's OK to have the restrictor that far away from the turbo, or if it should be right at the turbo. I know it <U>should</U> be right at the turbo, I just mean I can't put it at the turbo so is it OK being at the other end of the feed line?

does the restrictor is for raise the oil pressure of the engine... I mean if you dont use it too much oil pass freely in the turbo ??? I

A restrictor lowers pressure to the turbo. The turbo seals blow because the oil pressure is too high in most instances (like if you use a -4an line).

I know some people say a -3an line is fine but restrictors are like $10 so why not do it for peace of mind and longevity of your turbo.

ok but with a restrictor... does the turbo bearing could miss oil if you use a restrictor??? could I use only a 3 an line on my Precision SC50 ? I was going to order my line tonight ....

 

-3an. one year. no problems.
