I'm starting to look for forged pistons for a new motor with nitrous. Most of the forged pistons I see use 1/16", 1/16" 3/16" piston rings. I believe the stock pistons (& some forged) use 5/64", 5/64", 3/16" rings.

On a mainly street nitrous motor, what top/middle ring thickness is better? Why?

What other general knowledge about rings can you guys give me?
