Mike,
I'm building a dolley similar to yours.

I like your idea of lifting the car once the engine is out. THe way I figure it, I will need 26" + the height of the dolley (7") to clear the underside of the car. My Jack has a maximum height of 20". If I jack against the underside of the engine, I will have to lift the car in phases and remove the engine in phases. I think your idea of lifting the car over the engine will help this...How do you lift the car once the engine is down?

From the porsche users manual (that came with the car) it looks like they are saying that you can jack the car on an area right below the location that the torsion bar passes into the wheelwell.
It looks like this is the subframe to the car.
