Hey guys, I'm about to rebuild my motor after destroying my block and #4 piston. So, therefore I need new pistons. I would like to build this motor within the Honda Challenge rules which require OEM bottom end components. I would like to throw in P30 JDM B16 pistons in a B18C5 block with stock R rods and crank. Has anyone done this, with any B16 pistons (non pct)? Will the rods fit with the piston? Or is there modification needed? If so, what modification? Thanks!
