So im rebuilding a B18A1, i want to replace my thrust washers, but supposedly honda used either a (DAIDO) or (TAIHO), my old ones have a 9002 stamped on them thats all,does anyone know which ones i have?

 

The difference is supplier - you can use ether one. From what I understand over in Asia the Taiho is usually cheaper than the Daido; so the Daidos are "considered better". Regardless of your choice, either one will work. Be sure to do it right and check your end-play after you install the crankshaft no matter what.
