I ordered pistons(JE) and rods(crower)for a DOHC zc 9.5.1 and i noticed the invoice it says for zc (d16a1) i think that engine code is 86-87 integra, but dont i need the 88-89 integra (d16a3) pistons and rods,Or are they both the same, I hope i dont have to send them back. The bore and stoke on the pistons are . Bore -2.97 Stoke-3.54. i ordered them overbored, hope someone will be able to help.

 

they are the same thing. it will work.
