Guys,

Thank you for all of the info on coolant flow in the rotary.  The
solution
that I have favored thus far is to mount the punp on the left side
in my
case a pusher is on the spark plug side.  The outlet of the  Toyota
pump
will have at least (2) 90 degrre bends to get to the block inlet.
George
do
you have any info on the center housing cooling scenario?  Does it
use 2
pumps?

Joe, The available four rotor conversion kit ($9800) requires a
block off
plate on the front accessory housing and an outlet addition to the
stock
front cover  behind the water pump. There is not any water pump
listed in
the kit materials. The ones being sold on the internet show one pump.
Using a 3 rotor pump as far as I can determine requires a 3 rotor
front
accessory housing because it has a different bolt pattern than the
13B, The
aftermarket is offering a dry sump front cover which I can't find a
picture
of at the moment which as I recall has the extra water outlets.
Externally
it looks like the one Mazda ocassionally built except that it is
gear driven
rather than chain drive. The price is high just to avoid machine
work on a
stock front accessory housing but if you were looking to dry sump it
is a
deal.
