I'd look into the prop shaft angles being to great if you lower the engine too much, as well as exhaust clearance. Just some food for thought.

Why do you need to lower the motor?
Can the sump stuff work without lowering the motor?

There was a guy in the UK who had used a dry-sump on an F20C that was being used in a Lotus 7 style kit car. I forwarded the info to Dave a while back. I can look it up again if need be.
At a minimum it would be useful to get feedback on how it worked out.

On a somewhat related note, have you guys ever thought of putting in an electric coolant pump?
I have one of these, controler and pump, ready to install.
I'll be removing the oem water pump and fabing up an adapter plate.

Lowering the motor helps to lower the CG of the car. Its something like for every inch you lower 100lbs you increase your lateral G limit by 0.1g I probably have the values wrong but you get the idea. Its one of the primary benifits of going to a dry sump system.
The additional maintenance of cleaning the tanks/lines/filters, plus the maze of plumbing are the downsides to a drysump.
I'd say go for it, I'd really like to see one.

Wasn't the main reason for a dry sump to ensure adaquate oiling on high speed/high G corners? Less windage frees up some power, and lower engine height is side benefit.

Another benifit is to increase the oil capacity of the system(hence why it's 8qts), this will allow for greater heat aborbstion. However you still must be able to dissapate the extra heat(i.e. an upgraded radiator may be desired) and it will take longer to warm the engine up.

And just think, if our S2000 was priced in the M5 range maybe we could have gotten the BMW set up 
The oil pan has a bunch of different oil pick up points on both sides in addition to the front and back. The ECU is able to control which pick up points are used based upon the direction the car is g-loading, i.e. long right hand turn and the left pick up points are used...
Now that is what I call engineering a performance car.
