Lately I have been thinking about doing a camshaft change on my civic. I have an LS in there right now, and was curious as to how big of a change i can get away with. I don't want to have to re-tune my ECU or anything, but want as much of a change as I can possibly get. Any good companies to look at? Or would it have to be a custom job? Also, who makes the best cam gears? I havn't even looked at them before, so I am completely clueless about these. Thanks a ton for the advice!
