Just trying to help out a friend who races a Civic on a 1/3 mile oval asphalt track. He doesn't have access to a computer so I'm going to try and help him find the info he needs. First of all where I might I find a list of the varioustranny codes and gear ratios. Second of all he is told that the tranny he needs to try and find is the one from a 1985 CRX "SI". Did they make more than one version that year and does any body know where the best place and price to find one? Any help would be appreciated. Thanks, Dana from New Hampshire.
