Alright i finished taking apart my motor the other day. The motor is in mint condition, until I found out that I blew the ring lands on 3 pistons and 1 piston ring. Anyways, there are no metal shavings no scouring what so ever on the cylinders or the crank, and all the bearings are fine but I wanna replace the rod bearings for safety but its marked 12111-54C00. There are no colors so would that be standard? Last thing, since gti-r pistons and BB pistons are the same how come my piston is stamped 54c and 2 for the grade or is it the same for the BB as well?

nissan bearrings don't have colors fro what i noticed from dismantling my motor. just those numbers. all you have to do is call nissan and give them the numbers and they will give you the bearrings. the gti-r pistons i had were coded 54 c also. it is just a different grade than the bb i think.
