Neo Rb25De+T Turbo Drain.

[dori33]

I have a good condition 25de neo that will replace the current 25det in my drift car ( if it ever dies lol). my question is can I use the bunged factory head drain at the front of the motor (neo does not use it, solid lifters, smaller oil restrictors) as a turbo oil return. Will it be an acceptable way to return the oil to the sump with out restriction, or will it act as a vent when under positive pressure, pushing oil to the head.

I can't see why not... At least they stuck a bung in it, not just left you with a casting mark to drill through.

It won't act as vent, the exhaust side is suction, the inlet side is vent due to crank rotation.
