I've read that the NA and turbo model omps are different. I have a turbo and was already able to take measurements off of it, but i don't have a NA to work off of. I was wondering if someone could get the diameter of the oil feed hole on theirs. Turbo's seem to be around 3mm. The picture is of mine where I'm making a plug for it. Thanks in advance!

 

I have a spare that I can measure for you later today.

I believe the opening is the same, it's the flow rate that is different. The FSM has a different flow measurement for TII models.
