Yes I agree. 2j and 3s
Lots of people do not know this but the smaller the bore the more difficult it is to keep the piston quiet.(less skirt area to dampen the slap)
There is actually a formula for this. Almost like the ring gap one but more math.
The Wossner sounds like a good idea!
I know for a fact that a teflon coating helps with smaller bore engines
Why don't they just fit teflon inserts
Like buttons, I can actually see it working
Probably not cost effective! Haha!
PS, 2J does do 750whp on stock internals. Used to use toyota 4Y rings.
Don't even know why people forge them.
