newb piston ring question.........
 

my boy fried one of his rings or ringlands, haven't tore it down yet, but i found him some p73 usdm itr pistons that will give his b16 c/r of about 9.7:1, which may be a little more forgiving than the stock 10.2:1. anyways, he already ordered rings for the pr3 pistons, i know they're the same bore, but we can still use the pr3 rings on the p73 pistons right?

Yes they should be the same.
