Quick piston sizing question

[spudly13]

Im putting my l20 back together, since its apart i was going to just do a quick hone and rings, stock bore is supposed to be 85mm right? so with a pair of calipers i tried measing the cylinder, 84.61 is the most i can get out of it, and the piston 84.74,

Tops of the pistons are marked u23, now im assuming that that is std bore because it measures less then 85? so order std rings?

 

Thanks

 

Edit; those measurements were taken with a pretty cheap pair of calipers

I'll say. The Nissan specs for a std L20B piston is 84.984" to 85.035"

I go with standard and gap the ends!!!!!!!!!!!!!

 

cast rings seat fast.

 

prime the oil pump!!!!!!!!!!!!put oil in it before install. Im sure you know this but people forget
