I'm in the process of stoking a b18a using a b20a crankshaft, my problem is I know the snout is too long but I don't remember how much, I had detailed website I was using as reference, but I no longer have the link to it. (had to format harddrive.) it said something about 14mm was too long and needed to be shaved down to.... I know I could put both crankshafts next to each other and wing it, but my project is about 45 miles away, I have the b20a crankshaft here with me and while I'm get a few pounds shaved off of it in the next few days I would like to find out how much of the snout needs to go as well it order to fit the b18 pulley. anyone know of any good sites or reference materials on this? it would be much appreciated. Thanks Thomas.
