Has anyone heard of something call a fire-ring?
I have the aluminum 98mm cylinders with small steps in the top lips. I have been told that they are for fire-rings to allow for expansion of the heads and cylinders when heated. I also believe that they are used on later 964/993 motors, but I am not sure. Can anyone provide me with some info on these? There are more pictures than this one on my website... More pics of the cylinders... (IMG:http://www.britainsmith.com/Porsche/TurboMotor/Cylinders/images/130_3061_JPG.jpg) |
