actually, i think the EvoIII is the best Evo thats come out... the rest of them are just to cluttered up and complicated.

all Evos have had 7 bolts in them, but the Evo 1-3 was oriented the way our DSM's are. in fact, the Evo 1-3 will drop into the 2G's; the 2G's version of the 4G63 is actually a watered-down version of the Evo 4G63 and it was also American produced. It was built using the original Mitsu designs... but the Chrysler had their lack-luster quality control... and ive heard stories of someone in the engine block casting plant spilling/dropping something into a vat of iron... and then Mitsubishi ended up replacing 500 Short blocks or soemthing craze like that all following the same sequence of production.

i think the Evo8 uses an "evolved" version of the Evo7 motor... if that says anything.
