The RX8 engine solves the low profile water pump problem nicely.
     For all others it is not that hard to cut down the stock  pump as in
these photos.
     Just takes a little work with a dia grinder and a tig welder.
     The stock pump seems to pump just the right amount of flow for
     the HP generated in aircraft use while drawing less than 3 HP.

What happened to the remote side mounted pump?

Sold out. Got too expensive for most people anyway.
In theory it is better to have the pump mounted down low. If the coolant
gets low then it still circulates. This apparently is not enough incentive
to
pay $300 for a water pump. IMHO long term the RX8 engine will take over.

I still have one that I would like to sell: $280 plus shipping.

BTW Jim Mederer said he was dumb founded that the more or less stock water jacket on
the Mazda rotary was still capable of cooling the rotor housings at the 300 HP per 
rotor level let alone 400 HP per rotor level. He felt it should melt the rotor housing.  
I had to agree. I must say I am impressed on what a great job Mazda engineers did
designing the cooling system.
