Piston ring gap specifications?

[Jon K]

My friend who is building my bottom end is asking what I want to run in terms of ring gap and I told him "I am not sure."

I was wondering what the stock default ring gap setup is like for an M50 non vanos.

3?

Thanks for wasting my time Jeff.


Bill R/Winfred do you guys know? I have a formula given to me on how to open up the gap for Nitrous/Turbo, but I want to see how their derivative compares to the default gap.

Your very welcome Jon

Thanks for wasting my time Jeff

Found this, not sure if they are the numbers you are looking for.

Hey guys I am not looking for ring size, I am looking for gap size. Thanks though!

really for a smart guy you arent very resourceful now are you?
Piston rings : Gap: Top & bottom compression rings = 0.0080-0.0160" ; oil ring = 0.0080-0.0180
