Hello all

ive just picked a RB26 bottom end up from a 33 GTR V spec with 50k miles. it is a complete bottom end with forged rods, standard pistons, ACL bearings N1 oil pump and a tomei oil ristrictor in the block. the only problem is cylinder 6 has a melted piston there doesent seem to be any damage to the bore (the bit i can see) the rest of the bores are very clean im going to strip it down when i have time and space. just wanted to know what you guys thought for repairing ?

just wondering what to do.... wiseco 86.5mm pistons and rebore with fresh acl bearings ? or check the bearings for wear marks etc if ok re-use ?

all advice needed and welcome

After 50,000 miles I personally would throw new bearings in for piece of mind. They are not exactly expensive.
