only difference between a cyclone motor and a standard 4g63 is that it comes with a cyclone intake manifold. thats it. they're both 6 bolts..they cam exclusive in certain japanese vehicles, not u.s.

that doesnt mean eclipses were ever offered in japan. eclipses is a u.s. car only. same with the talons. we're all part of the chyrsler family. except with a mitsu badge and mitsu engine.
