Just a small FYI, on these engines the roller is on the cam lobe, not on the lifter. There are no "roller rockers". There is at least one thread on the forum where this is discussed and there are illustrations of the cams with the rollers built in the lobes. Kinda weird setup but it seems to work.
Now that you mention it, I remember seeing that. And wasn't the whole lifter setup unchanged? When they changed to roller cams, they didn't have to change anything else? If that's the case, then the performance cams should work with any year Mirage. (but, no, I'm not interested in them)
