If the car is for high RPM, a slightly larger gap is ok as very little gas/air gets through the gap a such a short time.
Hasting Rings says 0.014 " per inch of bore.

I'm sure there will be after market rings for sale. Most ring widths today are roughly the same for similar size pistons. I haven't stripped a 986 motor but I presume they are nikasiled, so get compatible rings. Ie not for cast iron.

I have a 2.7 motor in the shed just waiting for some spare time to give it a full overhaul.

There is no nikasil in any 986 engine.

Thanks for elaborating on that!
