Is it the same as a d15b2? Thanks, my local parts store thinks I'm a retard.

 

There are a series of numbers on the on the rods........and Letters on the bottom of the block where the oil pan gasket goes. Call Honda and give them these numbers and they have a chart to look up the rod size.

For ex.

BDBD on the bottom of the block
2,3, or 4 on the fat end of each rod


Good Luck!!
