I use a tranny jack. you can tilt the top to the angle of the car.
I also made 2 brackets to bolt the engine to the stand.
the 930 is a much bigger beast than the 911 and with it bolted to the jack that is a REAL big relief when doing the drop by myself.
it still moves around a little and you still need to be close to the balance point but it makes it so much easier.
I know its not much but it really makes me feel good when I can MAKE something like this instead of just buying it.
I also use the tranny jack to get the car even higher. I also take off the front wheels and drop the nose down and remove the rear bumper to get the motor out.
i think all i remove is the intercooler.
