Joe,
 
I remembered to take some pics this weekend.  The first one is taken from the plugs side looking down on the water pump.  You can see the blue aftermarket WP pulley, and the Renesis pump housing & cartridge.  The WP shaft is located closer to the engine C/L than on the 20B or 13B.  I had to relocate the alternator in order to get good belt wrap on the pump.  It also requires longer mounting studs which are available from McMaster Carr. 
 
I used PL's custom thermostat housing, but you could accomplish the same thing by welding an inlet and outlet directly to the WP housing.  I didn't want to risk warping the housing, so I went with the custom housing and welded wiggins style couplings to it.

Mark,
 
I assume the 20B is close to the 13b?  Got any pics?

Joe, 

I installed a Renesis WP on my 20B.  It is much lighter than the 20B pump and is more compact.  If you use a custom inlet/outlet, you could run the lines very close to the engine.  Mine are inside the c/l of the slide throttle.  

A point of clarification... The Renesis WP is part of the Renesis front cover.  Using a band saw, I separated the WP housing from the front cover.  So, I used the 20B front cover with the Renesis WP.

Someone on the list is using an EWP.  I don't remember who at the moment.
Maybe he will chime in later.

Bill,

My installation does not have enough room to use the stock RX7 pump.  I have
a Toyota Corolla pump that can with some modification be mounted on one side
of the motor.  I had to get a Denso alternator to get an alternator to fit
along side the motor.  I found a block that permits connectionof hoses to
where the pump used to be. The reason that I am asking all of these somewhat
strange inqueries is just to get a working scenario.  My firewall is 22"
wide and this is a pusher so things get worse as you go aft.  Another item
that takes a lotof room is the exhaust augmenter.  The engine is also a P
Port. I do not believe I can get the cooling right without some additional
means.  The shape of the cowls on a canard pusher is critical to effiency so
i am trying to stay tight.

I saw a video on a RX7 discussion group that used the Stewart EWP using the
similar block connection.  Don't know if it would work in an AC.
