Hi All,
Enjoying this thread, as I'm currently in the process of choosing pistons for an engine build. I have a few questions:
Firstly, what is an acceptable ring groove width size. In the piston below, the 1/16" groove measures 1.67mm. Is this ok?
Very sorry for the mix of metric and imperial, but I believe 1/16" is 1.60mm.
Some useful size pistons that I have, also have a 3/32" groove. Would these be readily available? They are +0.060" pistons.
Finally - Several pistons that I have looked at, have had these 'piston ring assisters' (see picture). What is their purpose? Are they piston specific or ring specific?
I may end up just buying new pistons, but I'd much prefer to try to reuse some old ones. I'm not looking to break any speed records - cruising at 40mph is enough for me.
Appreciate any help.
Regards,
Colin
