Perhaps its time for a new front cover. The best place for the water
  rad is
  turning out to be on the spark plug side of the engine.  Unfortunately
  that
  complicates the pluming somewhat because the water pump inlet and
  outlet are
  on the other side of the engine.  Perhaps we should take a page out of
  the
  RX8 design and make a new front cover incorporating the water pump
  housing
  with the water coming out and going in on the other side of the engine.
  Another problem is the pump should be mounted as low as possible so
  any drop
  in water level will not cause the pump to cavitate.  We built some
  remote
  pumps a few years ago that used the stock Mazda pump cartridge.  One
  other
  point is the pump would be more eff.  if the water came stright into the
  impeller.  Here are some shots of that remote pump.  I am looking for
  feed
  back here.  Does anybody else have an ideas they would like to see
  incorporated.

  What do you guys think of paying $200 for this proposed water pump
  cartridge?

  BMW High Performance Water Pump

  The BMW High Performance Water Pump is a direct replacement pump
  designed to fit a wide range of BMW engines with no modifications.
  That includes accepting the Factory Fan Clutch. The front of the BMW
  High Performance Water Pump is stock appearing giving it that classic
  BMW look while the back is all business.

      * Up to 20% increase of water flow over stock pump
      * Twice as efficient as factory pump
      * Much less parasitic drag than other pumps
      * Racing or Stock Factory Replacement applications
      * Stainless steel impeller
      * Heavy duty bearing
      * High quality water seal

  I like it as it would be easy to machine the new front cover to accept
  this pump cartridge. That is not the bottom line for the cost as one
  must start with a 60 pound block of aluminum at $3 or $4 a pound.
  Total $180 to $240 for material alone. We are not done yet as this
  does not include the price of machining.

  Is it worth it? I don't think so. Am I wasting my time here?

  One could get a RX8 front cover and cut the aluminum pump part off and
  it would fit a 13B. Or buy a 13B after market aluminum cartridge for
  $50.

  What do you guys think?

  I am for this 150%...I brought this up awhile ago............I would
  help in whatever way necessary to put this together...this is something
  sorely needed for an AC application...

  Find the right guts and we can machine components around it for our
  specific  design....

  what do you think???

  I don't know Jeff.... we are looking at least $600. A lot of aluminum
  to be hogged off and thrown away.

  I also like the Ford cartridge. What we would need for the Ford is a
  new WP housing that could be remote mounted. We would also need a
  water in and out fitting for the block.

  The cut off  RX8 pump could also be remote mounted in the same place.

  I think this would be a much cheaper way of doing the same thing.

  Of course there is nothing really wrong with the stock system and it
  works well.

 You get me or point in the direction of that impeller housing, I'll do
 the rest.......

 The Ford 4.6 L V8 cartridge shown is a high buck $150 Stewart Components
 racing version. Pep Boys probably has other makes for less than $100. Both
 will have the same dimensions. You can come straight in from the back side
 and build a radial scroll for the  output. We can test if for flow as
 function of RPM in the NC mill or lathe.

 Paul. It appears to  me after  checking  the posted pictures of mazda water
 pumps on the newsletter that this ford cartridge is of the opposite rotation
 probably due to a serpentene drive belt. The pump on my  2004 6L chev
 pickup  was like this with the  flat back side of the belt driving the
 pump.The chrysler pump used on the 361. 383. 400. 413. 426. and 440 engines
 is also a cartridge style. fairly compact and cheap. I bought some aluminum
 housing ones for $39 each for the front housing I designed for the four
 rotor. If this pump is too high a flow rating  it can be underdriven with
 the belt ratio. I don't think the BMW pump is a good candidate due to the
 installed height of such a long pump and the inlet turning 90 degrees into
 the pump, We have room for the rear center inlet and the option of reducing
 the inlet diameter to produce a higher warer outlet pressure from the pump.
