ok i have a b20 motor that i got with je pistons and crower rods in it. the block is sleeved and all that any ways. teh pistons it came with are je's 13to1 compression and we are gonna run 9to1s ok so i order them from endyn and the crower pin is far bigger than the hole in the edyn piston. so i call larry and he does not understand and sends out a new set next day air. se we try them and they do not have a big enough hole. so whats the deal??? all i see that crower makes in rod sizes are 19mm and 21mm. and je only makes 19 and 21. so are my crower rods and je pistons over sized? or are the eydyn pistons the wrong size? like maybe there 19mm for a d series?

 

had a similar problem, the machine shop bored to the proper size for me. this is w/ SOHC of course...and not a b20...
