I have a t3/t4 turbo a/r .60 On the part of the turbo imbetween the compressor housing and the turbine housing (where the oil feed line goes into) it's not level with the ground. It's hard to explain but, that piece is kind of at an angle facing the front of the car... like this \ (but not to extreme, maybe at like a 35/30 degree angle). I was told it is best to have this center piece of the turbo flat so when the oil comes into the centerpiece it lubricates both sides of the shaft equally instead of one side. I have been running a turbo for about 7 months or so. The other problem is I have a revhard manifold. If I flatten this center piece out the oil line would be hitting my manifold, I would need a 90 degree oil line fitting. Does anyone know what size I would need? Thanks in advance.

You should really clock the turbo so the oil inlet is facing straight up, the oil will flow a lot better. Just loosen the bolts that go around the inside of either side of the turbo and rotate it until the center section is straight up and down. You will probably have to take the turbo out to do this.

As for the 90 degree fitting, go to Southern Racing Supply in Savannah, that isnt far from Richmond Hill. It is either a 3AN or 4AN to 1/4" NPT, you might try a 45 degree fitting instead of a 90.

 

Thanks man.

 

Hey, I have to use a 90 degree fitting because if I use a 45 deg. fitting, it will not clear under the manifold, I cant put a line into it with a 45. Is a 90 ok?

 

I used a 1/4" to 1/8" adapter, then a 1/8" 90 deg elbow with my inline pro. fits nicely.

 

just use a 1/4"NPT to 4AN 90 deg fitting into the turbo inlet because that is cheaper than the 90 deg hose end. You can just use a straight hose end with that fitting, they are only like $5. Either way will be fine though.

 

I believe your feed line used a -3an fitting. What you'll need is a 1/8 NPT to -3an 90 degree brass fitting. Currently you are using a 1/8" to -3an straight fitting... if you clock your center cartridge you're line will hit. The 90 will take care of everything.

For your return line you'll most likely need to run an aluminum oil return flange with a 1/2" to -10an fitting if you run a stainless steel set up. Then run a -10an straight swivel connected to a -10an SS line. I can't remember how you have your oil pan tapped... but if you have a -10an bung you simply need to run a 90 or 45 -10 swivel to it. If you have a 1/2"-5/8" barbed fitting you can always slip the -10an SS line over it and use a regular hose clamp. You can also use a 1/2"" threaded to 1/2"-5/8" barbed fitting at the oil return flange and slip the SS line over it. That's the cost efficient way to go.
