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.

If a new front cover is in the works, perhaps it would be a good time
to incorporate the alternator system too, like the AeroVee.  It would
help the up and coming one rotor crowd a lot, in terms of weight.

That is not a bad idea but I think we need a lot more power than can be
provided by a built in alternator. However perhaps a outboard motor type CD
ignition would not be too much trouble.

Paul,
You might remember that I was looking to use the EMS from a Mercury direct-injection 2-cycle to provide a alternator, ignition, and power for direct injection. The Merc also has an airpump for orbital direct injection. The pump does double duty to provide 2-stroke oil. We could use that pump to inject oil for the apex seals. I stopped my pursuit of that system because I didn't have a wholesale connection and new parts were too expensive. Are there any boat sales guys in our group? I still think this would be a good fit.
Bill Jepson

Yes so expensive one would have to make his own.
