if it was the old style eclipse (rouded, says eclipse on the rear betweenbrake lights), there is only the 4cylinder motor. The new style (200-2001?) are the only one's that sport a v6, those are 200 HP, but from what I understand they are heavier and not faster....just what I read here once. Oh, and FYI the old style gs-t has 210 hp from a turbo 4 cyl, but never came in convertible I don't think.
