i believe every modded turbo rotary should have David's brace. every motor i build has his brace... when available.
since the pan flange/engine block mating surface is below the oil level, oil leakage at the pan/block is always a challenge. by milling reliefs for the ribs into the brace risk of lekage is greatly reduced.
David's did his brace right.
if the rib reliefs were not milled into the brace the item could be sold for less than half price. of course it would not work properly as it would only contact the ribs.
since torque on the pan bolts is limited to 100 inch pounds do be sure and re-tap all bolt holes so you get an accurate reading.
leakage prevention is of course only half the story here. David's brace also adds additional stability to the block and, again, it delivers a major advantage over the non-ribbed brace as it has so much more pan flange contact area.
i do hope things work out for not only another production run but continued availability.
