Posted January 8, 200322 yr comment_22581 These are the numbers on the top of the piston, P86 50. Anyone recognize this? I have nit measured the bore yet, the pistons have a silver dollar sized raised portion on the passenger side of the piston as well...Ideas? I was told they were some sort of european racing piston made by nissan...Thanks for any info.....Bri Link to comment https://www.classiczcars.com/forums/topic/4178-p86-50-piston/ Share on other sites More sharing options...
