Yes it has a rev limiter. About 4200 IIRC in park/neutral, though one time my rev limiter disappeared while I was in neutral. The rev limiter is around 6k rpm on a non-chipped atx zetec when in drive,, which I bounced off tonite for a little bit having some parking lot fun. Good luck on the 3L install into a contour that originally had a zetec.
