Lynn,
I think the ultimate idea for a plate type mount is to use a drawn steel
shape with indents for the lord mounts. Making the tooling for a short run for
hydroforming wouldn't be that hard, and you make 20 as cheaply as 1. I would
make the part the oil pan as well to save weight. That way you don't have the
multiple gasket sandwich problem. Since the RX-8 pan is so shallow it would be
an easy form. A bit pie-in-the-sky, but it would be a very elegant solution.
Dry sump inlet and outlets could be easily brazed on ...

I was going to suggest holding the TB on with garage door springs strung in
from the rudder.................
I raced for years with the stock pump and a oil control try sandwiched
between the pan and engine. I glued one stock gasket to the tray and one to the
pan. Never had a leak. Under braking the entire oil supply will end up in the
front case (cover) and oil pressure sags as you leave a corner.
I am not happy with the powdered metal oil pump parts. I saw an impeller
turn back into powdered metal at a race track. Racing Beat sells a pump with
heat treated rings and rotors, but they look to be powdered metal as
well. So I don't know if that is even possible? Dry sump pumps have much
bigger parts but also powdered metal.
The oil pan can be a short tray with a deep area located just about
anywhere you might need to put it.
So, a narrow sump along one side of the engine would work as well as
anything and leave as much room as you might need directly below the block. You
could also bolt up a pan of your own design to the bottom of the mounting plate,
and the plate would be the lowest part in the way of a radiator ducting system.
That might be of some advantage.
