As far as me calling the 420a a Mitsu engine, I was not. I was trying to imply that if it is a 420a, then it IS NOT a Mitsu engine.

I admit I know little of Eclipses... however, I do know that the 420a does come in some Eclipses, or at least the engines LOOK exactly like 420a's ... I have seen plenty of them in junkyards.
