I have a T04S 60-1 that Im getting ready to put on my car ( waiting on my HKS manifold which is in the mail... ) and while imagining how its going to fit, it seems that the oil feed/return will not be vertical. From the pictures I have found, the HKS flange seems to be perpindicular to the ground. When I orient the flange on the turbo that way, the feed/return is at a ~45°. Is that ok?

I know you can clock the compressor housing, but can I clock the exhaust housing too? If I take any of that stuff off, does it need to be rebalanced or anything?

 

Now I could be all wrong about this and maybe the flange the manifold isnt vertical...But I just wanted to know what I can do if it is. A friend said I could get a different exhaust housing? I dont know...It just doesnt seem right to me. It seems to me that a T4 manifold would be made to accomodate the whole T4 center section and hotside. Are all center sections and hotsides the same on all T4's?

 

Most turbos have a clamp to hold the exhaust housing to the center section ... loosen the clamp and rotate the center section.

 

The oil feed line does not need to be verticle because it is pressurized, but the oil return line needs to always be downhill because it is gravity fed. Now that doesn't mean that it has to be VERTICAL. It can have bends and such in it as long as no part of the hose goes below the return inlet in the motor and makes a "U"

M-P

 

I have the technical blueprints for garret turbos , the spec on the prints says within 35 degrees of vertical is ok...Max

 

What manifold are you using on your car?

 

make sure you put on a vented oil cap,or remove
the oil stalk line that has the check valve and vent
it with a filter to atmosphere. I rebuilt several turbos
before I figured this out. Inadequate venting of the
crankcase causes oil backup in turbo.
