Ok i have a guestion thats been on my mind for a while now. OK so say if i have a b18b block and i got it honed to which i did. What piston size do i use. Do i still use the standard 81mm or will i have to get a different size. Help guys need help here. Thanx

 

honing doesnt generally chang the bore size. it just cleans the bore and adds a good cross hatch for the new rings to seat to...

so, call the machine shop and double check if they honed or bored your block...
