But first I tried using the entire Renesis front cover. I gave up on that and just cut the water pump section free of the front cover and used the Renesis WP and the 20B front cover. Saved about 6 lbs. over the cast iron 20B pump. Not sure what you're asking about bolt holes. All the holes in the Renesis WP lined up with the 20B holes. However, it does take longer studs.

I have since gone back to the stoc= k CAS, but that's another story.

Bill,
My installation does not have enough room to use the stock RX7 pump. = =A0I have
a Toyota Corolla pump that can with some modification be mounted on one sid= e
of the motor. =A0I had to get a Denso alternator to get an alternator = to fit
along side the motor. =A0I found a block that permits connectiono= f hoses to
where the pump used to be. The reason that I am asking all of these somewha= t
strange inqueries is just to get a working scenario. =A0My firewall is= 22"
wide and this is a pusher so things get worse as you go aft. = =A0Another item
that takes a lotof room is the exhaust augmenter. =A0The engine is also a P=
Port. I do not believe I can get the cooling right without some additio= nal
means. =A0The shape of the cowls on a canard pusher is critical to e= ffiency so
i am trying to stay tight.

I saw a video on a RX7 discussion group t= hat used the Stewart EWP using the
similar block connection. =A0Don'= t know if it would work in an AC.
