I am thinking of getting a set of Jim Wolf S3 cams for my s13 sr20det redtop, I have tried to find alot of info on this cams but I just cant seem to find out what I want to know about them. Does the S3 cams take away from top end? I really would like to have some more top end with a set of cams with out having to take away alot from bottom end torque. Is this a good choice or should I buy from another brand of cams?
