idk = I don't know

I haven't seen 'rebuild kits' for our motors. You really will just be looking for rods, rod bearings, main bearings, thrust washers, pistons (which come with wrist pins), rings (which will usually come with the pistons), someone to hone and/or bore your cylinders, new head gasket, and new seals/gaskets. Summit sells a 'conversion kit' (as they call it) which is all of the seals/gaskets for the bottom end. I don't know if they make it for the Z6 though. Honda will likely have something like that. I know Honda has full head seal/gasket kits that come with the head gasket. The one for the B18C1 is over $200.

I pieced all my rebuild stuff together.
