Apex stator cover plug tor return oil

[rat4020]

I want to move my turbo return oil line fom the timing check port to the center larger port in the stator cover and tap a An port into it . But I really dont want touse the nylon stock plug, does anyone here know of a after merket billet aluminum plug . I tried a YFZ450 but its to small

You can drain the turbo oil back to behind the primary clutch as well. I have done it on a few units.

I ordered it from amazon, they will show differnt sizes though. The first one I ordered was too small so measure your plug. The plug needs to be drilled and tapped for a -8 oring boss port and the inside lip of the plug needs to be machined concaved to give a bit of distance between the flywheel bolt and the plug so it wont create a restriction to the return oil flow

Does this require a external pump and a resivoire under a rear mount turbo setup to work?

On a rear mount, yes it would require a return pump and a small resevoir is never a bad idea.

Ok thx would it be possible to be able to run the ruturn without a pump i have heard it is possible to run the return line using the engine vaccume but have not seen the setup would tapping a line to the oil fill cap on the top of the engine beside the coils work?

I don't think it would work on the Apex models, due to the turbo being mounted lower in the chassis. It works on FX Nytro models, but the turbo mounts higher which provides a down hill run for the oil to come back to the engine.
