I have a sleeved 2.0 gsr with a TE 67 and -3 line coming from my golden eagle sandwich adapter.

Everyone I know with this turbo doesnt use a restrictor, the person I bought it from recommends that i use one.

I have an equal number of people saying YES and saying NO.

Help, I dont know what to do. Using stock oil pump

 

It won't hurt anything to use a restrictor, so why chance it. Function7 makes a really nice one:

 

anyone else

 

it wont hurt it in any way so why chance it... run the restrictor

 

I also have a function seven restricter.

 

We typically do not recommend running a restrictor in a -3AN line unless the engine oil pressures are extremely high (i.e. over 85 psi @5000 rpm) since the -3AN line is already restrictive at lower pressures.

-A

 

I'm running a -3AN line and still getting some seepage from the bottom of the turbo and out the turbo inlet... not actively dripping, just a light filmy coating. Oil pressures seem to be in the 80 range at the top end even with a T off the turbo feed line for the oil pressure gauge.

How little flow is too little?

 

I do not recommend using a restrictor for that -3AN line as well. Not on a journal bearing series like that. No sir.

I agree

 

Exactly, alot more damage can be done by not getting the turbo enough oil. The -3 line is fine w/o a restrictor on a journal bearing turbo. It's easy to stick a restrictor on it and say "look, no more oil in the compressor housing", when you don't know until it's to late that you're doing damage to the turbo.

 

I have -3an and my car was smoking, oil in the chargepipe and some dripping out the exhaust. I have a b16a with itr oil pump and when my oil guage was working i saw 95 psi of pressure. THe turbo only had 1500 miles on it and has a great deal of shaft play. My return is mint all downhill. Resently i installed a restrictor and the smoke has decreases drastically.

The only problem i see with a restrictor is the pressure will increase but the volume will decrease (PV/nRT=PV/nRT)

 

The pressure inside the line will increase but not inside the turbo. The restrictor creates a pressure drop across itself. I also don't run restrictors on -3 stuff either.
