Types? They number in the low HUNDREDS, from the basic beetle or Type
I to some NATO aviation support vehicles, Type 338 and higher.

WoW ! ! ! I had NO idea, about all of that!

Since the Type 1 used SIX different engines over the years, and ALL of
those included variations, the type vs displacement thingy is a handy
way to determine if a person is just running their mouth or if they
actually know something about VW engines.

When you say 6 different Type 1 engines, is that difference defined by
displacement, or is there some other designation to differentiate among the
Type 1 engines?

But that has little to do with converting a VW engine for flight since
you should base your build on all new, universal replacement parts.

Are all of the Type 1 cases the same?

Thanks for all of the info, by the way.
